Injection‑Molding Process Parameters
- Barrel temperature: general range 180~260℃
- Feed zone：30～50℃
- Zone1：160～250℃
- Zone2：200～300℃
- Zone3：220～300℃
- Zone4：220～300℃
- Zone5：220～300℃
- Nozzle：220～300℃
- Melt temperature：220～280℃
- Mold temperature：20‑70℃. Higher mold temperature improves surface gloss and dimensional stability; proper mold temperature reduces internal stress and enhances transparency for transparent articles.
- Injection pressure：80‑140 MPa（800‑1400 bar）, avoid excessive pressure; up to 180 MPa（1800 bar） for thin‑wall packaging containers.
- Holding pressure：30%‑60% of injection pressure; sufficient holding time is required to reduce shrinkage.
- Back pressure：5‑20 MPa（50‑200 bar）.
- Injection speed：medium‑high speed. High‑speed injection replicates mold surface for good gloss; multi‑stage injection speed is recommended for complex or thin‑wall parts to avoid bubbles and excessive shear.
- Screw speed：high rotational speed with linear velocity up to 1.3 m/s is permitted, ensure plasticization finished before cooling cycle ends.
- Drying treatment：pre‑drying unnecessary under good storage; dry at 80℃ for 1 h under poor storage condition.
