Processing Parameters
| Process Parameter | Recommended Range | Key Control Points |
|---|---|---|
| Drying Condition | 100‑110℃ × 4‑6 h | Moisture content ≤0.02% (prevent hydrolysis degradation) |
| Injection Molding Temperature | 230‑260℃ | Gradient temperature rise for rear‑middle‑front barrel sections |
| Mold Temperature | 60‑80℃ | Temperature above 70℃ improves surface gloss |
| Injection Pressure | 60‑100 MPa | High‑speed injection reduces flow marks |
| Holding Pressure | 40‑60 % of injection pressure | Excessively long holding‑pressure time may cause stress cracking |
| Screw Speed | 40‑70 rpm | High screw speed shall be avoided to prevent thermal decomposition by shear heat |
| Recycled Material Ratio | ≤20 % | Repeatedly recycled material may degrade flame‑retardant performance |
