Injection‑Molding Process Parameters

Process Item	Suggested Range / Description	Remarks
Drying treatment	Generally unnecessary; dry at 80℃ for 1‑2 h if damp under poor storage condition	PP low‑moisture‑absorption feature.
Barrel rear zone(feed section)	180‑200℃	Prevent thermal degradation.
Barrel middle zone(compression section)	200‑220℃	‑
Barrel front zone(metering section)	210‑230℃	‑
Nozzle temperature	210‑230℃	‑
Mold temperature	40‑80℃, recommended 50‑70℃	Crystallization mainly determined by mold temperature. Low temperature: poor surface, weld‑line and flow‑mark risks; high temperature will cause warpage.
Injection pressure	70‑120 MPa	Higher pressure for thin‑wall or complex‑structure parts; high flowability allows properly lower injection pressure.
Holding pressure	40%‑60% of injection pressure	Prevent sink mark and excessive shrinkage; holding time accounts for ~30% of cycle time.
Injection speed	Medium‑high speed	High flowability supports fast injection for good filling performance.
Screw speed	Medium‑high screw speed	Avoid excessive shear heat leading to material degradation.
