Injection‑Molding Process Parameters
| Process Item | Suggested Range / Description | Remarks |
|---|---|---|
| Drying treatment | Generally unnecessary; dry at 80℃ for 1‑2 h if damp | PP low‑moisture‑absorption property. |
| Barrel rear zone(feed section) | 180‑200℃ | Avoid thermal degradation. |
| Barrel middle zone(compression section) | 200‑220℃ | ‑ |
| Barrel front zone(metering section) | 210‑230℃ | ‑ |
| Nozzle temperature | 210‑230℃ | ‑ |
| Mold temperature | 50‑90℃, recommended 50℃ | Crystallization depends largely on mold temperature. Low temperature: poor surface, weld‑line and flow‑mark risks; high temperature brings warpage risk. |
| Injection pressure | 70‑120 MPa(700‑1200 bar) | Higher pressure for thin‑wall or complex‑structure parts; high flowability allows appropriately 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 | High‑speed injection preferred | Reduce internal stress and deformation; not suitable for partial molds (risk of bubble and flow mark). |
| Screw speed | Medium‑to‑high speed | Avoid excessive shear heat leading to material degradation. |
