Explore the Structural Foam Molding Process From Design to Warehousing

Structural foam molding is a manufacturing process that is used to produce large-tonnage products. This process provides companies with numerous benefits, including its cost-effectiveness for the production of large parts, high moldability, and high durability. In this blog, we will walk you through the entire structural foam molding process, from design to warehousing.

How Does the Structural Foam Molding Process Work?

Design

The first process you must complete is the part design. During this process, our plastics engineers will help you design your part for manufacturability and decide on the right materials. Design for Manufacturability, or DFM, is the process of designing parts for easy manufacturing, saving you time and money during the process.

Next, you will need to design your structural foam mold. Again, our engineers will work with you to help determine the best mold design for your product. They take into consideration the specifications of your product, your product’s application, and the material you are using.

Production

The structural foam production process starts by mixing a melted polymer with nitrogen gas and/or a chemical blowing agent. This mixture is then injected into your structural foam mold under low pressure. The polymer then cools as it touches the walls of the mold. Forming a solid exterior with a honeycomb interior leads to a lightweight product compared to straight injection molding.

Secondary Operations

Secondary operations are done after the manufacturing process in order to make sure your products live up to your standards. This process includes assembly, decorating, and fabrication. Some of the most common services include drilling holes, kitting your products, and decorating them through pad printing, heat transfer, and hot stamping. This allows your products to perfectly meet your needs and your application as soon as they get to their final destination.

Warehousing

Finding a place to store your products after production can be difficult. Luckily, at Port Erie, we offer warehousing services for your products. We take your product directly from the production floor to one of our various warehouses or storage facilities. In providing you with warehousing services, you don’t have to worry about finding another partner or paying for transportation, saving you valuable time and money.

Structural Foam Molding Troubleshooting: Common Problems and Their Solutions

Structural Foam Molding Troubleshooting: Common Problems and Their Solutions

While structural foam molding is a very popular manufacturing process, some common issues can pop up during production. Fortunately, an experienced structural foam molding partner will be able to easily overcome and resolve these issues. So, what does structural foam molding troubleshooting look like? Let’s explore the most common issues and how you can fix them.

Structural Foam Molding Troubleshooting Common Problems

Sink Marks

When one region of the product cools more slowly than others, thicker regions may result, known as sink marks. This commonly occurs when the inner core of the product cools too rapidly, leading to depressions on the part surface, however, it can also be a result of inadequate venting during the production process.

Warping

Warping refers to part deformation caused by non-uniform cooling. This common issue can pose large issues for companies, as it makes the part unsuitable for its intended purpose. Warping is typically caused by an improper cooling rate and poor mold design.

Issues with Part Filling

When the mold is not filled all the way, the part filling will not form as intended. This causes the part to miss sections, making the product impossible to use. Generally, issues with part filling are caused by improper ventilation and inadequate material flow during the production process.

Fixing Common Structural Foam Molding Issues

Sink Marks

In order to prevent sink marks, you will need to re-evaluate parts of your manufacturing process. The best way to fix these issues is to adjust the cooling process so each area of the product cools at the same rate. This can be accomplished by implementing cooling channels and ensuring your mold is designed properly and contains adequate venting channels.

Warping

Since warping is also caused by improper and non-uniform cooling, you will need to adjust your manufacturing process to ensure the cooling process is ideal. This includes managing the cooling temperatures, implementing strategic cooling channel placements, and employing support structures to prevent the material from sinking.

Issues with Part Filling

To resolve issues with part filling, it is important to pay close attention to the design of your molds. Ensuring proper gate design and location and improving the ventilation of the mold will help prevent the mold from filling improperly.

Exploring the Wide Variety of Structural Foam Products

Exploring the Wide Variety of Structural Foam Products

Due to the nature of the plastics used and the manufacturing process itself, structural foam products have many benefits. The structural foam molding process is a popular manufacturing method used to create large-tonnage products because it is a low-pressure process. It puts far less stress on the product being produced and reduces the risk of warpage and damage from the manufacturing process.

Due to the many advantages of this process, structural foam molding is used to create a wide range of products. From garden and lawn equipment to construction products, structural foam products are found everywhere.

Common Types of Structural Foam Products

Large-Tonnage Products

Due to the low-pressure process, large molds can easily be made with aluminum rather than steel since they do not need to be durable enough to withstand the high-pressure process of injection molding. Additionally, this process allows for the large-tonnage product to be created in a single mold run while also preventing damage.

Complex Designs

Again, the low-pressure structural foam molding process is beneficial, allowing for complex products to be produced with ease. The structural foam can reach every corner of the mold while being manufactured, allowing you to design complex parts without the worry that they won’t have the right amount of detail.

Some of Port Erie’s Structural Foam Products

HDPE Trench Drain

A client came to our team at Port Erie with a project for the construction industry. They were using straight injection molding to create large trench drains. Unfortunately, the injection-molded trench drains had long cycle times and had issues with warp.

Our engineering team worked to redesign the product to be created through structural foam molding. This led to a 20% part weight reduction, 40% cycle time reduction, and less warpage. If you are interested in learning more about this project, read our case study. 

Garden Carts and Lawn Equipment

Our team worked to create a large lawn cart through structural foam molding. Since lawn and garden equipment need to be durable enough to withstand chemicals, the elements, temperature variations, and the sun, the properties of structural foam molding were necessary for this project.

Pallets

Choosing to use structural foam in pallets creates a durable, water-resistant, impact-resistant product. We have created plastic pallets for a number of companies using this manufacturing method. These structural foam molded plastics are durable and can be used for repeated use, however, they are also affordable.

What Are the Most Common Structural Foam Plastics?

What Are the Most Common Structural Foam Plastics?

As a popular manufacturing process, structural foam molding has become increasingly popular for creating large-tonnage plastic products. Structural foam plastic offers many benefits including design flexibility, high moldability, and durability. 

There are two common types of structural foam plastic used in this manufacturing process, each of which exhibits its own properties and benefits. Typically, customers choose from structural foam polyethylene or structural foam polypropylene depending on what characteristics they desire and need in their products. In this blog, we will explore each of these plastics and what they are best used for. 

Structural Foam Polyethylene

Polyethylene is the most commonly produced plastic. It is a durable, lightweight, closed-cell material that is found in many everyday household items as well as demanding applications.

Properties of Polyethylene

As a commonly produced plastic, polyethylene has many beneficial properties. This polymer exhibits good chemical, wear, and water resistance, as well as electrical insulation, good load bearing, and shock absorption. 

If you are interested in learning more about structural foam polyethylene in detail, check out our blog. 

Low-Density Polyethylene (LDPE) Versus High-Density Polyethylene (HDPE)

There are two common types of polyethylene, low-density polyethylene (LDPE) and high-density polyethylene (HDPE). Each has its own applications and advantages, however, HDPE is typically what is used in structural foam molding. 

LDPE

Low-density polyethylene exhibits low-temperature flexibility, toughness, and corrosion resistance. However, due to its low melting point, LDPE is not suitable for applications where temperature resistance and strength are required. LDPE is not suitable for structural foam molding due to its lack of strength. 

HDPE

High-density polyethylene has a high melting point, high strength, good chemical resistance, and good crack resistance. Since this polymer exhibits such good physical properties, HDPE is ideal for applications where strength and durability are required, thus making it suitable for use in structural foam molding. 

Structural Foam Polypropylene

Polypropylene is a rigid, lightweight, closed-cell polymer that is commonly used in various industries, including consumer goods, automotive, medical, and more. This polymer is commonly used in structural foam molding because of its numerous beneficial properties. These benefits include toughness, flexibility, fatigue resistance, chemical resistance, high-temperature resistance, good electrical insulation, compression resistance, impact resistance, and moisture resistance.  

These properties allow for structural foam molded products made from polypropylene to be used in critical and demanding applications. These include applications that are primarily outside, under UV light, exposed to chemicals and weather, or in varying temperatures. 

If You Are Looking for Structural Foam Plastics, Turn to Port Erie

Since 1953 Port Erie has been creating high-quality structural foam plastics. We primarily work with HDPE and polypropylene to manufacture durable, cost-effective structural foam molded products.

Structural Foam Polyethylene: Properties and Products

Structural Foam Polyethylene: Properties and Products

Polyethylene is a polymer commonly used in structural foam molding due to its various beneficial properties. Due to its affordability, easy availability, and numerous beneficial properties, this polymer is the most common type of consumer plastic and is used in everyday materials and products.

Properties of Structural Foam Polyethylene

Chemical Resistance

Polyethylene is resistant to many different chemical solvents, making it good for use in chemical, medical, automotive, and many other applications. This polymer is not affected by aqueous solutions of salts, acids, or alkalis.

Wear Resistance

Structural foam polyethylene is an extremely durable, high strength polymer, giving it the ability to be used in many applications in harsh environments. It is able to withstand harsh temperatures or applications in which the product may be subjected to physical stress.

Water Resistance

Since its molecules are so close together, polyethylene is very resistant to water. The material hardly absorbs any water, making it good for use in the food and beverage industry.

Electrical Insulation

Structural foam polyethylene does not conduct electricity well, making it a good insulator. So, if a durable plastic is needed for an application where conductivity is not required nor needed, polyethylene is a great option.

Good Physical Properties

In addition to all of its other great properties, polyethylene also has good load-bearing and shock absorption. These properties eliminate the impacts of friction and vibration on your product.

High-Density Polyethylene Also Offers Many Benefits

In addition to traditional polyethylene, you can also opt for High-Density Polyethylene, or HDPE. When compared to traditional polyethylene, HDPE is more flexible, but offers many of the same benefits, including:

• Weatherproof
• Affordable
• Chemical resistance
• Low moisture absorption
• Corrosion resistance
• Easy to fabricate and machine

Products That Are Created Using Structural Foam Polyethylene

Automotive Applications

With its corrosion resistance, wear resistance, shock absorption, and good load-bearing, polyethylene and HDPE are commonly used in the automotive industry. Common applications include bumpers and instrument panels.

Drain Pipes and Trench Drains

Drain pipes are responsible for facilitating the transfer of water from one place to another. This includes disposing of wastewater from buildings. Trench drains function in a similar way, however, they are responsible for the removal of excess surface water. Both drain pipes and trench drains can be created from HDPE and polyethylene.

At Port Erie, we helped one of our customers improve the manufacturing process for their trench drains. While they were previously using straight injection molding, they realized the process was taking too long and was yielding products with significant warp. When they brought their project to use, we decided to use structural foam HDPE to create a high-quality product that met all of their needs. Read more in our case study.

Flooring

Certain flooring options can be created using structural foam polyethylene or HDPE, including the DuraTrac Floors. These temporary outdoor flooring solutions need to be durable, weatherproof, and have good wear resistance.

Lawn and Garden Carts and Equipment

Garden and lawn carts and equipment need to be durable, able to withstand the elements, and be resistant to certain chemicals found in plant food, weed killer, or pesticides. Luckily, polyethylene and HDPE are able to withstand the outdoor environment.

Pallets and Large Totes

Many pallets and large totes are created from plastic in order to be durable, easy to clean, and able to be reused. Polyethylene and HDPE are common choices here since these materials are so durable, water resistant, chemical resistant, and have good physical properties.

At Port Erie, we have created durable plastic pallets that are able to be used repeatedly. Our pallets weigh less than 16 lbs, are 9 legged, and can handle up to 2,000 lbs.

Advantages of Structural Foam Molding You Should Consider

Advantages of Structural Foam Molding You Should Consider

Structural foam molding is a plastic manufacturing method that is used to create cost-effective, large-tonnage plastic products. During this process, nitrogen gas or a chemical blowing agent is mixed in with a melting polymer. This polymer mixture is then injected into a mold under low pressure. As the plastic touches the walls of the mold, it cools and solidifies, creating a product with a solid outer layer and a honeycomb-like interior.

The process of structural foam molding yields many benefits to both the manufacturer and the customer, including saving time and money on the process. Read on to explore many of the benefits this manufacturing process can offer if you need a large-tonnage plastic product.

What are the Advantages of Structural Foam Molding?

Easily Create Large Parts

If you have a large-tonnage plastic part or product that needs to be manufactured, the structural foam molding process may be the best option for you. Since the process is a low-pressure process, it requires less clamping force, allowing you to create tooling and molds from more cost-effective materials, such as aluminum. Additionally, the low-pressure process leads to less damage, meaning you don’t have to spend more time or money on rerunning machines.

Design Flexibility and Less Warpage

The low-pressure characteristic of the process makes the structural foam very easy to mold. Structural foam molding puts less stress on the product during its production, so it experiences significantly less damage than parts created through straight injection molding. With the reduced risk of damage, you can easily design and create a more complex mold that will maintain the desired shape of the finished product.

The low-pressure process also prevents warpage. There is less stress on the product during the production process, so it is less likely to warp or become damaged while being manufactured.

Multiple Molds Can Run at the Same Time

In addition to its ability to produce very large parts with ease, it is also possible to run multiple molds at the same time on the same machine with structural foam molding. Since it is a low-pressure process, these molds can run simultaneously without putting too much stress on the machines or the molds. Being able to run multiple molds at one time can save you both time and money on your manufacturing process.

Advantageous Physical Properties

Structural foam molded products have many desirable physical properties that make them ideal for use in many industries. These products have a high-strength-to-weight ratio, meaning they are lighter weight than straight injection molded, solid plastic products while still maintaining their strength and durability. They also exhibit good thermal stability and are able to withstand thermal expansion so they will not warp or lose their properties when exposed to extreme temperatures, making them ideal for hot and cold environments.

Structural Foam Molding vs Injection Molding: Which is Right for You?

Structural Foam Molding vs Injection Molding: Which is Right for You?

When designing your plastic project, it is important to choose the right manufacturing process. Ensuring you take your product’s application, size, and material into consideration before starting the manufacturing process will save you time and money while yielding a higher-quality product. Deciding on what process is best for your application can be tricky, so if you are wondering which is better for you — structural foam molding vs injection molding — we have outlined each below.

Structural Foam Molding

Structural foam molding is done by mixing a melted polymer with nitrogen gas and/or a chemical blowing agent. This mixture is then injected into a mold under low pressure and, as the polymer mixture touches the walls of the mold, it cools, forming a solid outer layer with a honeycomb interior.

The Benefits of Structural Foam Molding

Cost-Effective for Large Parts and Products

Since structural foam molding is a low-pressure process the materials used to create the tooling and molds do not need to be as durable as those for injection molding. This lowers the cost of your tooling production. Additionally, less raw materials are used in the process since the product isn’t entirely solid resin.

Highly Moldable

The low-pressure process of structural foam molding puts significantly less stress on the parts during the molding process. This leads to less warping and damage during manufacturing, which saves you time and money.

Weight Reduction

The honeycomb-like interior of structural foam molded products reduces their weight when compared to their injection-molded counterparts, allowing them to be used in a wide range of industries and applications.

What is Structural Foam Molding Used For 

Large Tonnage Parts and Products

Structural foam molding is the ideal manufacturing process for creating large, thick-walled parts and products. The low-pressure process allows these large parts to be created in a single cycle and prevents damage and warpage during the process.

Durable Parts and Products

The solid exterior of the product gives it durability and strength while the honeycomb interior makes these products more lightweight than their injection molded counterparts. This is especially advantageous for large parts.

Injection Molding

During the injection molding process, a polymer is melted inside the injection molding machine’s heated barrel. The machine is then closed and the mold halves close together and are held together under high clamp pressure. The screw in the barrel then pushes the molten polymer under very high pressure into the mold. Once all material is in the mold, the screw pulls back and starts cooling. When it is cooled entirely, the product is released from the mold.

Benefits of Injection Molding

Efficient Production

Injection molding is one of the fastest plastic manufacturing processes available. It is possible to create many parts in a short period of time through the injection molding process, allowing the manufacturing process to be completed faster.

Strength and Durability

Because injection molded parts are completely solid they are very durable. This also gives them uniform strength throughout the product.

Little Post-Injection Molding Processing 

Many times parts come out of the injection mold with good aesthetics and will require little to no finishing. Since you won’t need hardly any finishing services, you will save money on your manufacturing costs.

What is Injection Molding Used For? 

Complex Parts and Products

The injection molding process is high-pressure which allows the molten polymer to get into all of the nooks of the mold. This pressure allows for the creation of products with highly detailed and complex designs.

Exploring Structural Foam Properties

Exploring Structural Foam Properties

Structural foam molding is a great plastic manufacturing method for large objects and the inherent structural foam properties are beneficial to both the manufacturer and the customer. This allows manufacturers to easily create large plastic parts and products that are durable.

Structural foam molding begins when nitrogen gas or a chemical blowing agent is mixed with a melting polymer. This polymer mixture is then injected into a mold under low pressure. As the plastic touches the walls of the mold, it cools and solidifies, creating a solid outer layer with a honeycomb interior.

Structural Foam Properties You Should Consider

Weight Reduction

There is a considerable weight reduction between large injection molded products and large structural foam molded products. Due to the honeycomb interior, structural foam products are lighter than if the same part was made with straight injection molding. This allows these products to be used in a wide range of industries and in applications where injection-molded parts are simply too heavy.

Strong and Durable

The plastics that are used for the structural foam molding process have a higher rigidity than the plastics that are used in injection molding. This structural foam property results in a strong and durable plastic product.

Highly Moldable

Since the process is low-pressure, structural foam is highly moldable. It experiences less stress during the low-pressure molding process which reduces the risk of warping or deformities. This reduces the amount of products that are damaged during the manufacturing process, keeping it moving smoothly and saving you valuable time and money.

Reduced Resource Use and Waste

The process of structural foam molding uses fewer raw materials and less energy during production. Additionally, post-industrial scrap plastic is often used as a primary feedstock. This allows products to be manufactured in a more sustainable manner which is becoming increasingly important to consumers.

Cost-Effective Manufacturing Solution for Very Large Parts

Structural foam molding is a cost-effective manufacturing process for creating very large, thick parts, and very specific parts. This is because it is a low-pressure process, requiring less clamping force during the injection and curing processes. Because the clamping force is lesser, tooling and molds can be made from less expensive materials, such as aluminum. Producing very large parts and products can be costly, so saving money with structural foam molding can increase your profit margins.

Secondary Operations: Plastic Injection Molding Assembly and Finishing

Secondary Operations: Plastic Injection Molding Assembly and Finishing

Secondary operations are the processes of plastic injection molding assembly and finishing that occur after a part has been molded. These processes complete the production of plastic parts and add value to your products.

Assembly

At Port Erie Plastics, we have extensive experience with assembly, including having the ability to tackle complex assemblies. This includes multiple molded parts being assembled using purchased components such as latches, springs, rods, aluminum extrusions, and more.

In-Line and Off-Line Assembly

In-line assembly occurs during the production process. Workers are assigned a specific task and complete it before sending the product further down the assembly line.  On the other hand, off-line assembly occurs after the production of the individual parts has been completed.

Off-line assembly does have constraints and can be difficult work.  At Port Erie, we combine engineering and automation in order to complete as many processes as possible at the injection molding machine—saving time by consolidating and streamlining the production process.

Decorating

Pad Printing

This decorating technique transfers a 2D image onto a 3D plastic part using an etched plate. Pad printing allows for the printing of multiple colors on complex surfaces, such as concave or convex parts.

Heat Transfer

The process of heat transferring bonds high-quality digitally printed or screen-printed images to the plastic part or product using heat and pressure. Heat transfer allows for full-color printing and requires no cure time, so it is ready to ship right away.

Hot Stamping

Hot stamping combines heat and pressure to transfer pre-dried ink or foil to a plastic part. The process yields a reflective or high gloss color to raised areas. It is a durable printing process and can be paired with all thermoplastics.

In-Mold Decorating

In-mold decorating allows for the high-precision machining of plastic parts with specific colors and a high-quality appearance. During the process, a premade applique is placed into the mold before the injection molding process begins. The molding then takes place around the applique.

Port Erie Plastics can decorate both at the injection molding machine and in a dedicated, climate-controlled room depending on the process you select.

Fabrication

Drilling

Using a 6-axis robot, we are able to drill holes in plastic products for inserts or other hardware. This careful process creates clean holes and slots in the plastic without causing damage such as cracking or warping.

Welding

We are able to join two plastic pieces or parts together using ultrasonic welding techniques. Ultrasonic welding works by sending a high-frequency vibration through the pieces until they are held together.

Fastening

The process of fastening joins plastic parts together with fastening elements such as hinges, latches, screws, rivets, pins, and more. Fastening does not require any heat or welding in order to join pieces together.

Heat Staking

Combining heat and pressure, heat staking is used to join plastic parts together. Localized heating and cooling of the plastics all the material to be reformed and joined.

CNC Trimming

CNC trimming utilizes a pre-programmed route to remove excess material from a plastic part. This brings the piece to its desired shape and size so it is ready for use.

The Benefits of a Manufacturer With Plastic Injection Mold Building Capabilities

The Benefits of a Manufacturer With Plastic Injection Mold Building Capabilities

Businesses are always looking for ways to lower manufacturing costs and shorten turnaround times. One way they can accomplish these savings is by partnering with a manufacturer that can perform plastic injection mold building.

There are many ways in which in-house plastic injection mold building can benefit customers. From reducing transit times to offering higher quality products, let’s explore each of these advantages.

Shortened Turnaround Times

When manufacturers do not have in-house tooling or mold building capabilities, they have to outsource these services, making turnaround times significantly longer. Between additional transit times, manufacturing, and the potential for errors, outsourcing is costly in many ways.

Manufacturers that invest in their in-house tooling and plastic injection mold building can offer their clients lower costs and shorter turnaround times. There are no extra transit costs and customers can work closely with their manufacturer to ensure the mold comes out just right.

Lower Costs

It can be tempting to outsource your tooling and mold builds to low-cost countries to save money on manufacturing costs. However, it can be more expensive in the long run than working with a trusted domestic manufacturer. You will be spending a significant amount of money on transit and you risk receiving a low-quality product. With so much distance between you and your manufacturer, it is easy for important details to be overlooked, and quality control simply is not as good.

Transportation isn’t the only hidden cost with offshore tooling. Molds that are created overseas can be extremely difficult to run, making the manufacturing process much more expensive. Repairs on these molds are also very challenging, making it very expensive.

A domestic manufacturer with in-house tooling and plastic injection mold building ensures that you have regular communication about the status of your product. And, without worrying about international shipping, you can rest assured that you will receive a quality product at a lower price.

Your Manufacturer Will Own the Process

When your manufacturer builds your molds, they own the entire process. This simplifies the debugging of a new project, allowing for any necessary modifications to the mold design and any necessary repairs.

Quality Products

Working with a manufacturer with in-house tooling capabilities allows you to work closely with their team to ensure your products meet all of your standards. For example, when partnering with Port Erie Plastics, you will work with one of our engineers for any project you may have. We can source alternative resins for you, or rework your designs to make them easier to manufacture. This way, you have the peace of mind that your product will be of the highest quality and produced in the most efficient way possible.

Flexibility

In-house plastic injection mold building allows consumers to work closely with engineers to make changes and improvements to their molds and tooling easily. These changes can take place immediately, without the need to wait for delayed communication to occur, transit times, or extra costs.
