1、Wax mould surface is not smooth
Reason | Solution |
Wax temperature too low | Change the wax temperature and increase the wax temperature appropriately |
Wax injection pressure is too low | Increase wax injection pressure |
Mold temperature is too low | Reduce the amount of cooling ice |
Insufficient wax flow rate | Increase the flow rate of wax during wax injection |
| The mould surface is too rough | Make the mould surface as smooth as possible |
| Too much mold release | Reduce the use of release agents |
2、Wax mould burst
| Reasons for the formation | Improvement method and description |
| Hold time is too long | Reduce the holding time, before the wax has been cold set, still toughness but not hard brittle, remove the wax from the self-mold. |
| Improper mold opening and wax removal | The mold should be opened in sequence, and the wax embryo should be taken with care, not too much force. |
