Injection Molding Parameters
| Process Parameter | Unit | Recommended Range | Key Notes |
|---|---|---|---|
| Drying Condition | ‑ | ‑ | Strict drying is mandatory! |
| Drying Temperature | °C | 100‑120 | Avoid high‑temperature caking |
| Drying Time | h | ≥4 | Moisture content shall be ＜0.02 % |
| Barrel Temperature | ‑ | ‑ | Segmented control to prevent thermal degradation |
| Rear Section (Feed Zone) | °C | 260‑280 | Too low temperature causes poor glass‑fiber dispersion |
| Middle Section (Plasticizing Zone) | °C | 280‑300 | |
| Front Section (Nozzle) | °C | 290‑310 | Avoid excessive residence time |
| Mold Temperature | °C | 80‑100 | Affects surface gloss and internal stress |
| Injection Pressure | MPa | 70‑120 | Medium‑to‑high pressure required for high glass‑fiber content |
| Holding Pressure | % | 50‑70 % of injection pressure | Reduce sink marks; excessive pressure causes flash |
| Screw Speed | rpm | 40‑80 | Low speed to prevent excessive shear fracture of glass fibers |
| Back Pressure | MPa | 0.3‑0.7 | Stabilize plasticizing; prevent air entrapment |
