When designing a part that needs to have low friction and/or chemical resistance, consider nylon. We can help you produce toothbrushes, gears, or other custom plastic parts. Our custom plastic injection molds can last over 1,000,000 cycles. ICOMold’s experts can work with you to determine if nylon is the best match for your injection molding project.

Nylon (PA) or Nylon Polyamide is a common synthetic thermoplastic polymer that is popular due to its high melting temperature, tensile strength, low friction and resistance to chemicals. It is both durable and flexible. Nylon can be combined with other thermoplastics to achieve increased strength. Nylon can be combined with many additives to create different variants and material properties. Its overall versatility is just one of its many advantages.

Advantages of Injection Molding Nylon

Nylon’s wide variety of applications combined with the efficiency of injection molding leads to numerous advantages. Some of these primary benefits of using nylon for an injection molding project include:

  • High melting temperature
  • Low friction
  • Recyclable
  • High tensile strength
  • Chemical resistance
  • Chemical compatibility
  • Abrasion resistance
  • Temperature resilience

It is important to note that there are some limitations to nylon. First, it is flammable and will burn when exposed to an open flame. To counteract its flammability, flame retardants may be added. It is also sensitive to UV exposure. UV stabilizers may be added to nylon.

Injection Molding Nylon Specifications

Nylon (PA) is made of a combination of different monomer types. It is produced through the distillation of crude oil or from biomass. Nylon is classified as a thermoplastic because of the way it responds to heat. Like other thermoplastics, nylon can be heated, cooled and heated again without degradation. Its ability to be liquified is what makes it ideal for the injection molding process. Nylon’s properties:

  • Melting Point (°F): 428 ◦F
  • Tensile Strength: ~11,000 psi
  • Impact Strength: ~0.6 fit-lb/in notched Izod
  • Hardness Level: R115
  • Flexural Modulus: ~16,000 psi

Injection Molding Nylon Process

Nylon is often first filled with glass fibers to increase its strength. During the injection molding process, nylon is heated into a liquid form. Using pressure, nylon is injected into the cavity of a double-sided mold to create the desired shape. Once the custom part has cooled, it is released into a bin and then moved into post-processing for finishing touches. The advantage of using injection molding for your nylon parts is that once the custom mold has been made, it can be used over and over again, resulting in a large volume of high-quality nylon products.

Applications of Injection Molding Nylon

Nylon is commonly used as an alternative to rubber, latex, silk and low strength metals. Its strength, abrasion resistance and elasticity make it ideal for both consumer and commercial goods. Some common uses of nylon in injection molding include:

  • Toothbrushes
  • Food containers
  • Plastic fasteners
  • Clothing
  • Reinforcement for rubber tires
  • Automotive parts
  • Engine components
  • Mechanical equipment
  • Cookware
  • Rope
  • Thread
  • Fabric
  • Gears
  • Bushings
  • Plastic bearings
