Plastic components have become an important element in modern-day plane construction. Since World War II, plastic aviation components have been making planes lighter, more durable, and more fuel-efficient by replacing critical rubber parts. Nylon washers, in particular, work to evenly distribute pressure from a nut or bolt, protecting the surface and reducing the risk of vibration-related damage and loosened fasteners. These abilities make Nylon washers a popular choice in many industries, especially aerospace.
What Are the Various Types of Nylon Used and Why?
Nylon washers are composed of several types of Nylon, including Nylon 6, Nylon 6/6, Nylon MDS, and Nylatron, each of which have beneficial characteristics that aid in the reliable operation of aerospace equipment. These characteristics include chemical resistance, non-flammability, durability, and abrasion resistance.
Nylatron and Nylon 6/6 are popularly used due to their self-lubricating characteristics, which make installation and maintenance simple. They are also highly resistant to heat-related damage, which makes them ideal for use in extreme environments or near engines.
Compared to other materials, these high-performance engineering plastics are low-density and have a light enough weight to make them valuable additions to flying equipment and vehicles. Depending on the exact materials used, product engineers can expect nylon washers to have half the density of comparable glass or aluminum pieces and 1/6th the density of steel.
What Are the Key Aerospace Applications for Nylon Washers?
Plastics have replaced many metal components in aerospace applications. Engineers and designers can replace virtually any small metal piece with plastic alternatives. Plastic parts reduce the overall weight of equipment and provide greater design flexibility, as they can be produced through a wide variety of fabrication methods and don’t have the same design constraints as metal or rubber workpieces. Plastics are also easier to assemble and install, which further reduces labor costs and assembly errors.
Some of the most popular applications for Nylon components include light covers, piping systems, tubing, trolleys, and support handles. Nylon washers, in particular, are commonly found in the following aerospace applications:
Flight control systems
And other aeronautic assemblies

The 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.
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.
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.
Retaining washers can perform a vast array of tasks ranging from the very simple, such as those of the basic screw and washer, to the more complex, like what wire guides and quarter-turn fastener assemblies do.
New Process has a large array of options to meet your Specialty Washer designs. We possess an in-house capability to create any non-metallic washer needed for the job. With provided specs for inner dimension, outer dimension and thickness, we can create just about anything you need.
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 6/6is 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

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.
Common plastic stamping materials include:
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.

Nylon and acetal are commonly used in a wide range of manufacturing applications. As both materials are a semi-crystalline thermoplastic, some of their characteristics overlap, such as their fatigue resistance, chemical resistance, and wear resistance with a sharp melting point. Additionally, both are appropriate material choices for the creation of small components such as washers, discs, and spacers. However, while there are some similarities in properties and use cases, the two materials remain distinctly different and are not entirely interchangeable.
One of the most obvious differences between nylon and acetal lies is aesthetics; acetal is shiny, while nylon appears dull in comparison. They also vary in regard to performance. For example:
Compared to acetal, nylon offers superior tensile strength and bending stiffness. It can also handle higher loads and higher temperatures. However, it is susceptible to damage from UV radiation unless special additives are incorporated into its formula and reacts poorly to changes in humidity, which cause it to swell and lose tensile strength.
Compared to nylon, acetal provides higher impact resistance and cold resistance. It is suitable for moderate loads.
In the following article, we provide an overview of acetal and nylon—outlining what they are, their properties, their key benefits, and typical industry applications—to facilitate material selection.
What Is Acetal Plastic?
Acetal—also known as polyoxymethylene (POM)—is a synthetic polymer commonly used in precision engineering. Similar to other semi-crystalline thermoplastics, it has good chemical resistance and fatigue resistance. It also demonstrates excellent tensile strength, good dimensional stability and machinability, and low material weight and frictional properties. It is often used for the manufacture of stiff, dimensionally stable components that need low surface friction.
What Is Nylon Plastic?
Nylon is also a synthetic polymer, as well as one of the most commonly employed engineering thermoplastics in the industry. It is highly durable, demonstrating resistance to damage from abrasion, chemicals (such as alcohols, oils, and solvents), and tearing. These qualities, combined with the material’s low cost, make nylon a suitable option for all manner of industrial and commercial applications.
Properties of Acetal Plastic
As indicated above, acetal plastic is valued for its machinability and many advantageous physical characteristics. Some of the key attributes of acetal include:
Chemical resistance: excellent
Coefficient of friction: low
Dimensional stability: excellent
Electrical properties: good
Porosity and moisture absorption: low
Tensile strength and stiffness: excellent
Wear resistance: excellent
Availability in FDA and USDA-compliant grades: yes
Properties of Nylon Plastics
The properties of nylon somewhat overlap with acetal, including regard to the following:
Chemical resistance: excellent
Coefficient of friction: low
Wear resistance: excellent
Availability in FDA and USDA-compliant grades: yes
However, the material also offers better thermal resistance, durability, and performance for the given price point.
Benefits of Acetal Plastic
Both nylon and acetal are suitable for use in applications that call for general-purpose engineering plastics. However, there are a few reasons why you may choose acetal over nylon. For example:
When manufacturing parts that require high dimensional stability
When the finished part or product will be regularly exposed to humidity or moisture
When the chemical and wear resistance of the material is critical
Benefits of Nylon Plastic
As a self-lubricating material, nylon is increasingly popular as a replacement for metal components that require external lubrication. Compared to parts made from metal, parts made from nylon are also much lighter, produce less noise during operations, and have longer service lives.
Nylon also offers advantages over other thermoplastics. For example:
Compared to acetal, it has higher temperature resistance, tensile strength, and stiffness, as well as lower material cost.
Compared to all other semi-crystalline thermoplastics, it offers the highest dielectric strength (in 6 cast formulas).
Industry Applications for Acetal and Nylon
As both acetal and nylon are highly versatile, it would be difficult to list all possible industry applications for either material. Additionally, since both materials are semi-crystalline thermoplastics, their similar material properties make them suited for similar use cases.
Common Acetal Plastic Applications
Acetal is used for the manufacture of a wide range of parts and products, including the following:
Electrical parts and padding
Wear strips and padding
These components might end up in medical devices, conveyor systems, or other similarly complex assemblies.

However, beyond its use in clothing and other commercial goods, it also finds application in many industrial parts and products. Similar to acetal, it is regularly used for the production of the following components:
As with acetal, these components are highly versatile and may be used in any number of industries. For example, nylon parts are often found in medical instruments, plumbing systems, and sprinkler systems. They also serve as alternatives to metal, wood, and rubber components in many engineering applications.
Nylon & Acetal Washers
Although washers are often thought of as made exclusively made from metal or rubber, thermoplastic washers have grown in popularity over the years. The main function of washers is to distribute the pressure experienced by a fastener across a larger surface area while also protecting the fastener and attachment surface. They can also help disperse vibrations produced during operations to minimize the risk of the fasteners loosening over time.

Excellent thermal insulation and chemical resistance properties make polytetrafluoroethylene (PTFE) suitable for many commercial and industrial applications. PTFE—more commonly known by DuPont’s brand name, Teflon™—is widely used to create solutions for the plumbing sector, such as washers and plumber’s tape.
Benefits of Teflon
PTFE is a good raw material for fabricating industrial parts due to its many beneficial properties. Some of these include:
Better heat resistance than Nylon, making Teflon washers ideal for use in heat-generating electrical equipment.
Exceptional thermal and electrical insulative properties—PTFE can withstand up to 500 volts per mil and up to 600° F.
High resistances to most common chemicals.
Poor water absorption, making Teflon suitable for use in wet environments.
The lowest coefficient of friction among all plastics, so it doesn’t typically require any sort of lubrication.
Excellent dimensional stability and creep resistance, despite high compressibility.
With these properties, Teflon parts provide consistent performance over a long service life. This makes PTFE a more cost-effective raw material than other plastics in many applications, including plumbing.
Common Plumbing Applications for Teflon
Teflon’s chemical inertness and hydrophobic properties make it a widely used material in the plumbing industry. Common plumbing applications include:
Washers used in plumbing are almost exclusively made from PTFE. Teflon also repels oil, so these washers are useful in piping or process systems that move oil or oil-containing fluids.

Choosing the right plastic is essential to the success of every manufacturing and packaging project. Most plastics are formed from any of six different popular plastics or a plastic mixture with concentrations of different resins.
Short-term storage containers, such as bottles and jugs, are usually made from high-density polyethylene (HDPE). This is a versatile and robust plastic. HDPE plastic containers are identifiable by the numeral “2” printed inside the container’s recycling symbol.
An Overview of HDPE
High-density polyethylene is produced from petroleum. It is a thermoplastic polymer—a polymer that melts into a liquid for easy forming and shaping. Manufacturers can easily create strong, customized containers by melting and treating HDPE.
The material is also ideal for custom printing and coloring, making it one of the most common materials for packaging. HDPE can also be made food-safe and it withstands caustic chemicals.
Given this versatility, it is used to make a variety of common containers such as:
One of HDPE’s most essential characteristics is its strength. The plastic has a high degree of tensile strength, so it is resistant to breakage from tension and impact damage. HDPE also has a high melting point, so it won’t degrade from heat under general, non-factory conditions. These features make the material ideal for producing reliable containers for consumer products and materials being transported.
Other benefits of using HDPE include:
Resistant to corrosion, even when holding liquid
Can be melted and reshaped
High strength-to-density ratio, making it cost-effective for transporting materials and products
Differences Between HDPE and LDPE
High-density polyethylene is just one type of polyethylene. Low-density polyethylene is lighter and more flexible.
During fabrication, HDPE’s polymer chains endure minimal branching. This keeps the polymer’s linear molecules closely knit together. The chains crystallize in a tight formation, which gives HDPE its rigid and relatively dense structure. It can hold a firm shape, even under pressure.
Conversely, the polymer chains of LDPE undergo significant branching and spreading. The polymer chains are more diffuse and scattered, giving them much less structure. This makes the material lighter, more flexible, and more susceptible to damage.
As such, HDPE is preferred for most manufacturing and packaging purposes. It can form reliable, structured products such as toys, garbage cans, storage containers, jugs, and pipes. Recently, HDPE has also begun to replace cardboard as the preferred material for fireworks tubes. The plastic material is less likely to shatter during malfunctions and can be recycled once the firework has been used.
Low-density polyethylene is used to produce cling wrap, plastic bags, and other unstructured products.

Lexan has low flammability, high polish, and glass-like clarity. However, for applications like eyeglasses, it requires a scratch-resistant coating since its surface can be easily scratched.
It’s flexible and can be molded without cracking. Lexan can be repeatedly heated and cooled without any deterioration in its properties.
It holds up well to high temperatures and corrosive chemicals.
Where Is Lexan Used?
Common Lexan applications touch every part of our lives. Industries that often use Lexan include:
Aerospace and automotive: These industries use Lexan to make strong but light windshields for planes, trains, and automobiles. This material is also used to build bullet-resistant windows for automobiles and isolation walls for bank counters.
Defense: Military manufacturers value Lexan for its light weight and high strength. This material is used to build components for military vehicles and jet fighters. Several accessories carried by soldiers are also made with Lexan to reduce the total weight that they carry.
Technology: The technology industry, especially electronic component manufacturing, uses Lexan because it insulates well against electricity and resists heat and corrosive chemicals. Lexan is used in large quantities to make CDs, DVDs, and Blu-Ray discs as well as computer and television screens. Lexan’s low weight and high impact resistance also make it suitable for use as laptop and cell phone cases along with video game controllers.
Environmentally friendly products: Eco-conscious products are composed of Lexan because this material is highly recyclable. Reusable water bottles, food containers, canteens, and glasses are made with Lexan. Lexan is far better than glass for these applications since it resists fractures while retaining the transparency of glass.
Why Is Lexan So Widely Used?
Lexan is so widely used because its properties make it an attractive raw material for industrial manufacturing. It has the good characteristics of similar materials like glass and acrylic without any of their weaker properties. Furthermore, Lexan’s undesirable qualities like poor scratch resistance and susceptibility to yellowing by UV rays can be easily addressed with protective coatings.
The main reason for Lexan’s large-scale use in manufacturing is its high impact resistance. It’s 200 times more impact resistant than glass, whereas acrylic’s impact resistance is only 8 times that of glass.
Additionally, Lexan can be fabricated in layers to make it bullet resistant. It’s also used to make containment-grade sheets to protect against forced entry with sledgehammers and similar tools. Bullet-resistant and containment-grade Lexan is much more cost effective than glass during fabrication and shipping.
Components made with Lexan are suitable for use in harsh environments because of Lexan’s resistance to high temperatures and harmful chemicals like acids. Despite its toughness and strength, Lexan is light and flexible, which makes it suitable for making eyeglasses, computer screens, and TV monitors.
