PDI Molding is a premier provider of plastic injection molding services. Our advanced high-tonnage injection molding equipment works well with nearly all common polymers and plastics used in injection molding. Our comprehensive job shop gives us additional value-added capabilities that enable us to handle orders in any volume.

For injection-molded parts that require exceptional rigidity and strength, we offer glass-filled nylon as a material option. While this material can sometimes be challenging to work with, PDI Molding has developed and sustained excellent technical competency with glass-filled nylon for injection molding.

 

Properties of Glass Filled Nylon

Pure nylon fails to withstand heat and UV light, so it is often modified in various ways to improve specific properties. Adding glass fibers to the nylon produces beneficial properties such as:

  • Increased rigidity
  • Improved hardness
  • Superior tensile strength
  • Increased creep strength
  • Greater dimensional stability
  • High mechanical damping

When Should You Use Glass Filled Nylon in Injection Molding?

Glass-filled nylon is used when the final product must withstand heat, chemicals, stress, or other harsh operating conditions. Some of the advantages of glass-filled nylon include:

  • Stiffness. Glass-filled nylon features stiffness up to 80% more than regular nylon materials.
  • Thermal tolerance. The thermal expansion rate of glass-filled nylon is only about half of standard nylon materials, which means it won’t deform easily due to abrupt changes in operating temperature.
  • Durability. Glass-filled nylon features up to 70% more tensile strength than unfilled nylon, which means components made from this material can handle significant stress without bending or breaking.

While glass-filled nylon has a number of advantages, it also has some properties which will need consideration in the design process:

  • Rigidity. Glass-filled nylon requires a higher level of part analysis to accurately determine molded in stress.
  • Abrasive. The abrasive nature of glass-filled nylon causes wear on tooling and mated parts.
  • Weight. Glass-filled nylon may be up to 15% heavier than comparable unfilled nylon.

Experience Molding Glass Filled Nylon Components

Plastics Design International has the skills and equipment required to undertake complex glass-filled nylon injection molding projects. Our capabilities, skilled team, and advanced equipment allow us to adhere to extremely tight weight and dimensional tolerances. We can handle injection molding projects of nearly any complexity, including designs that call for nylon and glass-filled nylon materials.

Glass-filled nylon injection molding is often an ideal choice when the required component must be strong, stable, and resistant to chemicals and oils. For more information about glass-filled nylon for injection molding for your project, please don’t hesitate to request a quote.
