Injection Molding Parameters
| Processing Item | Recommended Range / Operating Points | Notes & Explanations |
|---|---|---|
| Pre‑drying | Mandatory drying. Dry at 100‑120 °C for 6‑8 h. | Moisture content shall be controlled below 0.1%, to prevent molecular‑weight reduction and product defects caused by hydrolysis. |
| Barrel Temperature | Rear zone：280‑320℃；Middle zone：300‑320℃；Front zone：300‑320℃ | Melt temperature normally controlled at 310‑320℃. Temperature shall never exceed 330℃ to avoid material degradation. |
| Mold Temperature | 80‑120 °C. | Higher mold‑temperature reduces internal stress, improves surface gloss and dimensional stability. |
| Injection Pressure | Adjust according to product structure and wall‑thickness; medium‑high pressure is suggested. | Ensure complete mold filling. |
| Injection Speed | Medium speed. | Excessively high speed causes jetting marks; too‑low speed leads to insufficient filling. |
| Back Pressure | 2‑10 bar. | Promotes melt homogenization. |
| Screw Speed | Medium speed, 100‑200 RPM recommended. | Avoid excessive shear force which may break glass‑fiber and cause material degradation. |
