| Trouble Shooting for Product Defects |
| Production with flashing | crack when ejecting |
| reason | solution | reason | solution |
| machine | injecting pressure too high | reduce injecting pressure | plastic material is injected too much | Reduce material |
| plastic material is injected too much | reduce plastic | injecting pressure too high | reduce injecting pressure |
| ejection pressure too low | increase pressure | ejection pressure too low | increase pressure |
| mould | Mould cavity or parting line is dirty | check and clear | mould temperature is too low | increase temperature |
| Ejection chamfer is not enough | check and repair |
| ejector pin/plate is not back | check and clear |
|
|
| Ejection is unbalance | check and repair |
| ejector pin not enough or with wrong location | check and repair |
| Ejection cause mould vacuum | opening or ejection slowly, or add venting groove |
| Parting line is not fit | check and repair | Slider moving location is not fit | check and repair |
| material | material temperature too high | Reduce temperature |
