Injection‑Molding Process Parameters
| Process Item | Suggested Range / Description | Remarks |
|---|---|---|
| Drying treatment | Generally not required; dry at 80℃ for 1‑2 h under damp storage condition | PP features low moisture‑absorption. |
| Barrel melting temperature | 220‑275℃ | Do not exceed 275℃ to avoid degradation. |
| Mold temperature | 40‑80℃, recommended 50℃ | Crystallization degree depends largely on mold temperature. Low temperature: poor surface quality, weld‑line and flow‑mark risks; temperature above 90℃ will cause warpage easily. |
| Injection pressure | Maximum up to 1800 bar | ‑ |
| Injection speed | High‑speed injection to minimize internal pressure; adopt low‑speed injection under higher melt temperature for surface defects. | ‑ |
| Runner & gate | Cold‑runner diameter:4‑7 mm. All gate types are available; typical gate diameter 1‑1.5 mm. For edge gate: minimum depth ≥ half of wall‑thickness, minimum width ≥ twice wall‑thickness. Hot‑runner system is fully compatible with PP. | ‑ |
