Comprehensive Guide to PA6 Injection Molding

2025-11-24

Polyamide 6 (PA6) represents a widely utilized engineering plastic celebrated for its outstanding mechanical properties, wear resistance, and self-lubricating characteristics. Successful injection molding requires precise control of multiple process parameters.

Temperature management proves critical throughout the process:

Barrel temperature: 220-260°C

Nozzle temperature: Slightly below barrel temperature

Mold temperature: 70-90°C (enhances flow and reduces stress)

Pressure parameters must be carefully balanced:

Injection pressure: Adjusted according to part complexity

Screw speed: Moderate to prevent excessive shear heating

Additional critical factors include:

Cooling time: Optimized for complete solidification

Ejection force: Controlled to prevent surface damage

Material drying: 4+ hours at 80-100°C (<0.3% moisture content)

Through meticulous parameter control, manufacturers can fully leverage PA6's material advantages to produce high-quality components meeting stringent design requirements.
