Plastic washers are discs with a center hole similar to metal washers and are used largely to spread the load of a fastener. Plastic washers prevent sparks due to their nonmetal nature, making the workplace safer and more dependable. In addition, plastic washers reduce maintenance downtime, which further streamlines manufacturing. Read More…

Plastic Washer Material
There are numerous materials available for plastic washers. The ideal material relies on the particular requirements of an application. Here are some typical materials of plastic washers:
Nylon Washers
Available in a variety of varieties, nylon is a highly elastic synthetic material that offers elasticity, resistance to abrasion, chemical inertness, and machinability. Due to its superior absorption and insulating qualities, this material is preferred for chemical and electrical applications. When weight is an issue, nylon washers offer a strong, portable alternative to metal washers.
Teflon Washers
Also referred to as PTFE, Teflon is well known for having a very low friction coefficient and being impervious to water and oil. Teflon offers exceptionally high thermal and chemical resistance properties compared to other washer materials. These washers have low friction, making them perfect for plumbing, HVAC, and automotive applications.
Delrin Washers
Delrin is a proprietary homopolymer that delivers dimensional accuracy, hardness, and endurance in heavy-duty applications. In addition, it has a stable crystalline structure. Delrin washers are perfect for applications ranging from residential items to military equipment because the material is also impact- and temperature-resistant from -58 °F to 194 °F (-50 °C to 90 °C).
Polyethylene Plastic Washers
These are washers made of high-density polyethylene (HDPE) and low-density polyethylene (LDPE). The adaptability of LDPE washers makes them perfect for applications requiring water resistance in drains, water infrastructure, and liquid feeds. HDPE (high-density polyethylene) washers are more suitable for industrial and mechanical applications that value abrasion and crush resistance because they are tougher and less flexible.
Manufacturing Plastic Washers
Non-metallic stamping and injection molding are the two most widely used processes for obtaining and producing nylon washers. Non-metallic stamping has become a popular, low-cost substitute for injection molding because of its outstanding quality. The non-metallic stamping method may cut sheets of plastic and other thin non-metallic materials at extremely high rates using standard or high-speed punch presses and various dies.
Stamping Process
The stamping procedure produces massive volumes of plastic washers using a strong and high-production mechanical press. Washers can be produced in standard sizes or to special requirements. New combinations are less frequent since plastic stamping plants that manufacture washers frequently have a large library of old dies to choose from. Most washers are flat, and thick sheets of plastic are used in their construction.
A frame, bolster plate, and ram make up the three primary parts of a stamping press. Hundreds of washers can be made quickly and easily using this straightforward procedure. The finished frame is firmly clamped to the plate before the steel die is fastened to the ram. The heavy ram then exerts enormous power against the plastic sheet to carve out the washer pattern.
Injection Molding
Non-metallic stamping has become a popular, low-cost substitute for popular injection molding because of its outstanding quality. The non-metallic stamping method may slice strips of plastic and other light non-metallic materials at extremely high rates using standard or high-speed punching presses and various dies.
A plastic injection molding production technique is made for making big or medium-sized batches of identical items. It typically begins to have the edge over other approaches from just a few hundred pieces. Additionally, it is the technique that the plastics sector uses the most.
Advantages of Plastic Washers
- Impact Resistance: Impact-resistance glass and shields are made of materials like polycarbonate. Nylon or Polyurethane will isolate stress points and absorb impact shock to safeguard adjacent components. They can withstand the environment, particularly water.
- Fire Resistance: There are flame-safe and flame-retardant grades of several plastics. The price of previously required fire-suppression systems has decreased thanks to these goods, and in some circumstances, insurance rates in high-liability applications have also decreased. They are non-flammable and able to resist high temperatures.
- Vibration Resistance: Plastic washers can withstand vibration.
- Light Weight: Plastic washers are a logical substitute to reduce the weight of vehicles, aircraft, and other products.
- Insulating Properties: For electricity or temperature applications, non-metallic washers are a great alternative that doesn't throw off sparks.
- Food and Medical Usage: A wide variety of plastics, including those suitable for food applications, heart pump valves, and endoscopic equipment, have been certified for use in clinical uses.
- Low Cost: Plastic is less expensive than metal.
