Injection Molding Processing Parameters
| Processing Stage | Parameter Item | Suggested Range / Operation Notes | Unit / Remarks |
|---|---|---|---|
| Pre‑drying | Drying Temperature | 110‑120 | °C |
| Drying Time | 8‑12 (or at least over 4 hours until moisture ＜0.02%) | h (dehumidifying dryer recommended) | |
| Allowable Moisture Content | ＜ 0.02% (0.015‑0.02%) | Critical requirement | |
| Injection Temperature | Rear Barrel Temperature | 220‑230 | °C |
| Middle Barrel Temperature | 260‑280 | °C | |
| Front Barrel Temperature | 240‑260 | °C | |
| Nozzle Temperature | Slightly lower than front‑barrel temperature (e.g. 5‑10 °C lower) | °C | |
| Melt Temperature | 270‑320 (do not exceed 310 °C to avoid degradation) | °C (actual melt temperature shall be confirmed by air‑shot test) | |
| Mold Temperature | 80‑100 | °C (higher mold temperature reduces internal stress, improves filling and surface appearance) | |
| Injection Settings | Injection Pressure (screw‑type) | 80‑130 (or approx. 850‑1400 kgf/cm², max. up to 2400 kgf/cm²) | MPa (or kgf/cm²) |
| Holding Pressure | 40%‑60% of injection pressure | MPa | |
| Back Pressure | 3‑14 (or ~10 bar, approx.1 MPa; may decrease if no silver streaks or color‑mixing defects) | kgf/cm² or bar | |
| Screw Speed | 40‑70 | rpm | |
| Others | Injection Speed | Relatively fast injection speed commonly adopted (e.g. electrical switch parts); slow‑to‑fast injection profile is typical | Avoid melt fracture or poor venting caused by excessive speed |
