To ensure production efficiency and part quality, we recommend the following parameters for WY-111BR PC resin.
Temperature: 120-140℃
Time: 4-6 hours (Dehumidifying dryer recommended)
Moisture Content: Must be ≤ 0.02% to avoid bubbles or silver streaks.
| Stage | Recommended Range | Notes |
| Barrel Temp (Front) | 260-280℃ |
Use higher end for thin-walled parts.
|
| Barrel Temp (Middle) | 270-290℃ |
Critical plasticization stage; keep stable.
|
| Barrel Temp (Rear) | 250-270℃ |
Avoid early material degradation.
|
| Nozzle Temp | 280-290℃ |
Prevent nozzle clogging.
|
| Mold Temp | 80-100℃ |
Improves gloss and reduces internal stress.
|
| Injection Pressure | 80-120 MPa |
Increase for thin-wall parts to avoid short shots.
|
| Holding Pressure | 40-60 MPa |
Hold for 5-10s to prevent shrinkage.
|
| Injection Speed | Medium (30-50mm/s) |
Avoid bubbles (too fast) or weld lines (too slow).
