Plastic Extrusion Guide

Plastic extrusion is a highly customizable fabrication process that uses thermoplastic resins and a pre-shaped die to create components at high volumes. This manufacturing method can utilize different extrusion techniques based on the needs of the end application.


Polyethylene plastics are some of the most commonly used plastics on the market today. They are found in products you use every day, from water bottles to sandwich bags to garbage cans. Polyethylene plastics can be further broken down into High-Density Plastics (HDPE) or Low-Density Plastics (LDPE).

Polyethylene plastic is created through the polymerization of petroleum. Although HDPE and LDPE are both polyethylene plastics, they have visible differences. This is due to the differences in the manufacturing process. LDPE has an amorphous structure that isn’t organized, while HDPE has either a partially or completely crystalline structure, making it stronger and more durable.

High-Density vs. Low-Density Polyethylene

HDPE WashersHigh-density polyethylene is a petroleum product. This polymer is melted into liquid form for easy molding and shaping. This allows manufacturers to create custom-shaped, durable containers. During manufacturing, HDPE experiences very little polymer branching, keeping the molecular structure very tight. The resulting material is strong and more rigid with the ability to retain its shape under pressure.

HDPE is ideal for projects that require custom printing or coloring. Since it’s both easy to manufacture and incredibly strong, it’s a preferred material for packaging. HDPE can also be made food-safe and it is capable of withstanding caustic chemicals.

LDPE is a lighter and more flexible plastic. LDPE polymer chains experience a considerable amount of branching and spreading. Since the chains are separated or scattered, the plastic has far less structure. The resulting plastic is lighter and more flexible. Its softness, however, means it is prone to damage.

Similarities Between HDPE vs. LDPE

There are numerous similarities between the two polyethylene plastics. Both plastics have a low material weight, are highly recyclable and have a high impact strength, and can be resistant to water vapor, weathering, and even chemicals. The tensile strength of both plastics ranges from 0.02 to 0.40 N/mm2 and are cost-effective to manufacture. Polyethylene is naturally inert, which provides both HDPE and LDPE with excellent mechanical and electrical properties.

Differences between HDPE & LDPE

The different production methods of the two substrates give them very distinct properties. These include:

  • Physical Characteristics: HDPE is much sturdier than LDPE. LDPE has a lower melting point and the products are usually more transparent than HDPE products. LDPE is slightly abrasion-resistant but is the more fragile of the two plastics. HDPE is more rigid. This durability makes it more resistant to chemicals. It has a higher melting point, which means it can withstand greater temperatures. Unlike LDPE, it’s much less transparent. HDPE is fully abrasion-resistant.
  • Recyclability: Both plastics can be recycled, but have different recycling requirements. LDPE is a recycling number 4 product and is more difficult to recycle due to its softness, increasing the risk of binding or clogging recycling machinery. HDPE is a recycling number 2 product and is easier to process through the recycling equipment.
  • Production Methods: HDPE is manufactured by heating petroleum to an extreme temperature. This releases ethylene gas monomers, which combine to form the polymer chains. LDPE is created by compressing the monomer ethylene gas within a tubular reactor, or autoclave, to facilitate linking monomers, creating the polymer chain.

Applications of HDPE vs. LDPE

LDPE washersHDPE and LDPE are often used in the same industries, but for different purposes. These industries include:

  • Hydraulics and pneumatics
  • Automotive
  • Packaging
  • Pipe and Piping
  • Electrical

HDPE plastics are used in applications such as:

  • Food processing
  • Chemical and petroleum manufacturing
  • Pharmaceutical processing

LDPE plastics are used for applications such as:

  • Food processing
  • Paper processing
  • In the marine market

Types of Thermoplastic Extrusion

Plastic extrusion involves a top-mounted hopper system that feeds thermoplastic resin through an extruder barrel. With the help of heat and pressure, the plastic takes the shape of the mold. Manufacturers can incorporate additives like colorants and UV inhibitors to enhance the appearance or performance of the final product.  

Extrusion works with a variety of thermoplastic materials, including:

  • extrusionTeflon PTFE
  • Nylon (6, 6/6, MDS)
  • Polypropylene (PP)
  • Low-density polyethylene (LDPE)
  • High-density polyethylene (HDPE)
  • High-impact polystyrene (HIPS)
  • Flexible polyvinyl chloride (PVC)
  • Acrylonitrile butadiene styrene (ABS)
  • Thermoplastic elastomers (Santoprene®)
  • Polyethylene terephthalate glycol (PETG or Codar®)

There are five main types of plastic extrusion methods that use different types of extrusion dies. We will describe the benefits and applications of each type of extrusion to help you determine the ideal method for your application.

Sheet Extrusion

Sheet extrusion works by extruding a molten plastic material in powder, flake, granule, or pellet form through a die into a flat shape. Rollers cool the sheets, which can be between 0.2 and 15 mm. Thin sheets are ideal for consumer products, while thicker sheets are best for industrial or commercial applications. The following are examples of applications for these extruded flat sheets:

  • Washers
  • Spacers

new process washersThe Various Types of Non-Metallic Washers

Washers comes in different shapes and sizes depending on their specific application, but are generally hardware components that are used to distribute force, prevent leaks, space out other components, and alleviate friction. A few examples of our most popular washers are plain/flat washers, self-retaining washers and our specialty shapes category.

Plain Washers

While there are a variety of washers on the market, perhaps what most individuals are familiar with are our flat washers that primarily distribute force and protect the object to which the fastener is being anchored. They are available in an array of materials, also coming in custom inner dimensions, outer dimensions and thickness. In situations with pre-drilled holes, plain washers can be used to rectify improperly sized holes that are too big for the fastener.

The following plain washers are some of the more commonly seen and are each used for different applications:

  • Flat washers are multi-purpose washers that can adequately perform in most standard situations.
  • Shoulder washers are typically used to insulate screws and wires.
  • Fender washers see broad usage in automobiles, plumbing operations, and electrical systems.
  • Torque washers are used to prevent nuts from spinning.
  • C-washers are slotted washers that are designed to be easily maneuvered and readjusted.

 Self-Retaining Washers

At New Process Fibre we have extensive experience with stamping a variety of washers to meet the needs of our customers in a variety of applications. When manufacturing our non-metallic washers, one particular specialty is our self-retaining washers, which we stamp flat with protrusions coming out of the inside diameter to easily grip the screw. Typically, we stamp these tabs with triangles or stars, but we can accommodate other designs as well and we can offer hex IDs as well as slit IDs that can offer a bit of give.

  • In the automotive industry, it’s common to work with upright screws. Retaining washers are preferred for this scenario because they remain affixed as they’re screwed in.

A couple of our most popular specialty designs tend to be “C” shaped and “D” Shaped washers

  • C Washers are especially important due to their ability to be placed in hard to reach spots without taking pieces apart. The washer’s actual “C” shape opening allows for it to be latched on easily.
  • D Washers are specially cut in order to be used in substitute of flat washers due to space limitations. The D washer’s special cut and dimensions allow for this unique fit.
  • In addition to our special shapes, another key benefit of these washers is that they are PSA (Pressure Sensitive Adhesive) and can be placed into the spots they need to be while the job is being worked on. This allows for a worker to freely use both hands on the job.

Types of Non-Metallic Materials

Non-metallic washers are made from synthetic materials, polymers, and plastics in a variety of different colors. Frequently used materials include:

  • Acetal Copolymer. Acetal copolymer is a stiff synthetic material that has excellent strength, durability, and dimensional stability, which helps prevent Acetal copolymer washers from deforming during manufacture and use.
  • Stiff, strong, and highly resistant to impact damage, Delrin homopolymer is a common alternative to the traditional plastics used to create non-metallic washers.
  • Washers composed of Nylon are lightweight, non-toxic, and feature high resistances to friction, fire, and corrosion.
    Nylon 6 and Nylon 6/6: Nylon 6is the same material found in fabric, but we use it as a replacement for brass, steel, aluminum, and other metals. Its high strength makes it suitable for gears, spacers, washers, and plumbing parts. Nylon 6/6 is a high viscosity Nylon with exceptional strength and temperature resistance. It is often used in chemical and electrical applications.
  • Suitable for wet or submerged applications, Mylar washers resist shrinkage, do not absorb a lot of moisture, and won’t change shape from moisture absorption.
  • Teflon â Teflon ÒPFTE is a pseudo-invulnerable synthetic material that easily withstands physical force and chemical damage.
  • High/Low Density Polyethylene. Low density polyethylene washers are valued for their flexibility, which makes them useful in applications that require a tight seal on geometrically unusual joints. High-density polyethylene washers are stronger than LDPE, but less flexible.
  • Vulcanized Fibre. Comprised of wood pulp, paper, and rag material, vulcanized fibre outperforms many standard materials with its light, stiff, and tough qualities.
  • Lexan has high impact resistance and a high strength-to-weight ratio. It is 200 times more impact resistant than glass while being 5–6 times lighter.
  • Ultra-High Molecular Weight Polyethylene. Perfect for applications that require a leak-free seal, ultra-high molecular weight polyethylene washers have a low-friction surface while also resisting abrasion, chemical damage, impact damage, and moisture

Why Choose Plastic Stamping?

Plastic stamping offers an ideal plastic forming method for the affordable production of simple plastic goods in virtually any volume. When compared to machining, plastic stamping offers lower material costs, better repeatability, and faster production speeds when creating custom plastic components.

An essential process for many industries that create plastic and polymer parts, successful plastic stamping requires experienced personnel and state-of-the-art equipment to ensure success. This blog will explore the plastic stamping process, it’s benefits, and some of the available options it provides.

What are the Major Benefits of Plastic Stamping?

Plastic components are prized for their low weight, varying levels of hardness, and resistances to chemicals, heat, friction, and deterioration. Beyond this versatile range of physical properties, plastic stamping process offers a variety of other benefits, such as:


Plastic stamping machinery creates precisely manufactured components. Using durable dies to cut plastic parts from stock material, plastic stamping equipment offers excellent repeatability between parts within very tight tolerances. As long as the plastic stamping die stays in good condition, accurate and dimensionally consistent parts can be produced in virtually any volume.

Aesthetic Component Appearance

Plastic stamped components are blanked in a single operation, drastically lowering the likelihood of error. Components created via plastic stamping have crisp, uniform edges and an overall high level of uniformity that contribute to their aesthetic appeal. This single-operation process often minimizes or mitigates the need for secondary finishing processes.

Speed and Cost Efficiency

The speed at which identical components can be produced is often considered the ultimate benefit of plastic stamping. Some manufacturing facilities contain high-speed punches that are capable of cycling at speeds as fast as 400 strokes per minute while still producing highly precise components. Large-volume orders are extremely cost-effective, and the speed at which plastic stamping machines operate provides additional economies of scale on larger orders.

What are the Key Material Options fo Plastic Stamping?

Plastic stamping materials have variable characteristics in terms of appearance, elasticity, plasticity, strength, hardness, brittleness, and more. While a standard material is available to suit most applications, plastic materials can be formulated with specific physical characteristics in mind. Plastic materials also typically come in a variety of colors and can be easily color-matched when necessary. This makes it relatively straightforward to tailor the material to the part’s intended application. vulcanized fibre parts

Common plastic stamping materials include:

  • Film
  • Foam
  • Laminate
  • Phenolic compounds
  • Plastic compounds
  • Rubber compounds
  • Vulcanized fiber (fish paper)

When deciding upon a material to use, the material’s brittleness plays a key role in the selection process. Hardness and brittleness tend to cohere, making it vital to select a material for the intended component that is hard enough to withstand the rigors of the intended use case without sacrificing formability.

Is Plastic Stamping Ideal and Affordable?

The plastic stamping process relies on a punch press and an associated set of stamping dies that punch an extruded plastic stock sheet or coil stock into the form specified by the design. As the stock material moves through the machine, pressure is applied to a single die or multiple dies in succession to cut the part from away from the stock. This method is ideal for the high-volume production of simple, flat items such as gaskets, seals, washers, laminations, and more.
