Injection‑Molding Process Parameters

Process Item	Suggested Range / Description	Remarks
Drying treatment	Generally not required; dry at 80℃ for 1‑2 h if damp	PP low‑moisture‑absorption characteristic.
Barrel rear zone(feed section)	160‑200℃	Avoid thermal degradation.
Barrel middle zone(compression section)	180‑220℃	‑
Barrel front zone(metering section)	200‑240℃	‑
Nozzle temperature	200‑240℃	‑
Mold temperature	30‑50℃ / 40‑80℃，recommended 50℃	Crystallization depends largely on mold temperature. Low temp: poor surface, weld‑line and flow‑mark risk; High temp: warpage tendency.
Injection pressure	80‑140 MPa(800‑1400 bar), max 1500‑1800 bar	Raise pressure for thin‑wall or complex parts.
Holding pressure	30%‑60% or 80% of injection pressure	Prevent sink mark and excessive shrinkage; holding time accounts for ~30% of cycle time.
Injection speed	High‑speed injection minimizes internal pressure; adopt low‑speed under higher melt temperature for surface defects.	‑
Screw speed	Permitted high screw speed (linear velocity 1.3 m/s)	Complete plasticization before cooling phase ends.
Runner & gate	Runner diameter:4‑7 mm. Pin‑point gate:length 1‑1.5 mm, min diameter 0.7 mm. Edge gate:short length (~0.7 mm), depth=1/2 wall‑thickness, width=2×wall‑thickness. Mold venting: vent depth 0.025‑0.038 mm, width 1.5 mm for good exhaust.	‑
