Nylon Injection Molding

Nylon Injection Molding Process Overview

Drying

Nylon is thoroughly dried to remove moisture and prevent degradation during molding.

Injection

Molten nylon is injected into a precision steel or aluminum mold under high pressure.

Cooling & Solidification

The nylon cools and solidifies, taking the exact shape of the mold cavity.

Ejection

The finished part is ejected from the mold, ready for use or further processing.

Advantages of Nylon Injection Molding

  • High strength and stiffness for structural parts
  • Excellent wear and abrasion resistance
  • Good heat and chemical resistance
  • Cost-effective for high-volume production
  • Supports complex, detailed designs
  • Can be reinforced with glass or carbon fiber

Disadvantages of Nylon Injection Molding

  • Absorbs moisture, affecting dimensions and properties
  • High shrinkage during cooling
  • Flammable and may emit toxic gases when burned
  • Some grades are more expensive than other plastics
