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)	160‑200℃	Prevent thermal degradation.
Barrel middle zone(compression section)	180‑220℃	‑
Barrel front zone(metering section)	200‑240℃	‑
Nozzle temperature	200‑240℃	‑
Melt temperature	‑	220‑280℃
Mold temperature	20‑70℃, recommended 40‑60℃	Crystallization mainly determined by mold temperature. Low temperature: poor surface, weld‑line and flow‑mark risks; high temperature will cause warpage.
Injection pressure	80‑140 MPa(800‑1400 bar)	Higher pressure for thin‑wall or complex‑structure parts.
Holding pressure	30%‑60% of injection pressure	Prevent sink mark and excessive shrinkage; holding time accounts for ~30% of cycle time.
Back pressure	5‑20 MPa(50‑200 bar)	‑
Injection speed	Medium speed; high‑speed injection required for thin‑wall packaging containers.	‑
Screw speed	High screw speed(linear velocity 1.3 m/s) is permitted	Complete plasticization before cooling phase finishes.
Runner & Gate	Pin‑point gate or multi‑point gate; hot‑runner system(heated / insulated type). Gate shall be set at thick‑wall position of product, otherwise shrinkage defect easily occurs.	Mold‑design suggestion.
