What is Nylon (Polyamide) Plastic?

Nylon, also called polyamide (PA), is a semi-crystalline thermoplastic commonly used in injection molding. Lightweight density, thermal stability, low friction performance and chemical resistance make nylon injection molding a standard choice for mechanical and industrial parts. The material takes dye well, liquefies when melted for recycling and maintains safety performance under high-friction and elevated-temperature applications.

Why Nylon (PA) Is a Standard for Injection Molding

Nylon PA is one of the most commonly molded plastics across industrial and mechanical markets. Low friction, chemical resistance, abrasion durability and thermal stability make nylon injection molding a standard for gears, fasteners, bearings and high-friction mechanical parts. Industries often shift to nylon polyamide as an accessible alternative to plastics, wood, rubber and metal.

High-Quality Characteristics for Nylon Injection Molding

Nylon is a synthetic thermoplastic polymer widely used for injection molding. Common benefits include:

High melting temperature
Low-friction surface behavior
Strong tensile performance
Resistance to chemicals and abrasion
Reliable heat soak tolerance in friction-heavy mechanical parts

Retlaw Industries also molds glass-filled nylon polyamide into rigid, high-strength components requiring reduced flex behavior and elevated structural stability.

Challenges with Nylon Injection Molding

Nylon injection molding material behaviors include:

Gassing: Excess gas can impact surface appearance and part stability. Temperature tuning and controlled venting reduce gas-related molding effects.
Moisture: Nylon PA takes in moisture when left in loaders and lines. Barrel heat soak and material line clearing support stable melt flow during nylon injection molding cycles.
Shrinkage: Nylon shrinkage can occur during molding. Heat profiling, mold temperature control and cooling cadence reduce shrink-related effects.
