Custom Nylon Molding Solution

Zhongren specializes in custom nylon injection molding services for applications that require high strength, wear resistance, and thermal stability. Our experience in nylon molding allows us to produce precision parts with excellent dimensional accuracy, chemical resistance, and load-bearing capability. Nylon injection molding is widely used in demanding engineering environments where metal replacement, long service life, and mechanical strength are critical.

How Are Nylon Parts Manufactured?

We offer full-service polyamide injection molding, combining optimized tooling, material selection, and process control to meet your technical requirements.

  • Nylon Injection Molding
  • Nylon Overmolding
  • Nylon CNC Machining
  • Insert Molding with Nylon
  • Nylon Extrusion Molding

Proper mold design and moisture conditioning are critical to avoid warping, shrinkage, or poor surface finish in injection molded nylon parts.

Common Applications of Nylon Molding

Due to its strength, wear resistance, and thermal durability, nylon molding is ideal for:

  • Gears, bushings, and bearings
  • Automotive under-the-hood components
  • Industrial mechanical parts
  • Electrical housings and connectors
  • Consumer appliance internals
  • Structural components replacing metal

Our Valued-Added Services

Advantages of Nylon Injection Molding

  • Excellent strength-to-weight ratio
  • High wear and abrasion resistance
  • Stable mechanical properties at elevated temperatures
  • Good chemical resistance to oils, fuels, and solvents
  • Glass-filled and flame-retardant grades available

Disadvantages of Nylon Molding

  • Absorbs moisture, affecting dimensional stability
  • Prone to shrinkage if not properly dried
  • Can warp without proper tooling and processing control
  • Limited UV resistance without additives

FAQ of Nylon Injection Molding

Why choose nylon for injection molding?

Nylon injection molding is ideal for producing durable, high-load components that must maintain structural integrity over time. It’s commonly used to replace metal in applications needing strength and reduced weight.

Moisture absorption is a key concern, pre-drying is essential. Improper tool design or insufficient drying can lead to warping, voids, or inconsistent dimensions.

Yes. Nylon overmolding is often used with metals or glass-filled materials for added strength, but careful attention is needed to ensure proper adhesion and shrinkage control.

Yes. We work with a wide range of polyamide injection molding grades including glass-reinforced, flame-retardant, and lubricated nylons to meet various mechanical and regulatory requirements.

Nylon 6/6 and other reinforced grades can withstand continuous use up to 120°C–150°C, making them suitable for automotive, electrical, and industrial uses.

Standard tooling takes 2–4 weeks. Once validated, production can begin quickly depending on part complexity and order volume.
