How to deal with the non-sticking of bubble gum mold

Foam mold refers to the mold used to produce various foam products. Similar to other mold processes, the phenomenon of adhesion will also be encountered in the foam mold process, and this phenomenon occurs more frequently due to the nature of foam. Therefore, if these situations occur, how to deal with and ensure that the incidence of this situation is reduced? Here is a brief introduction to Bian Xiao, a manufacturer of EPC foam machine in Hangzhou.

1. Check whether the ratio of release agent is abnormal, try to replace the release agent, and adjust the spraying position and quantity;

2. Modify the mold cooling system, adjust the die casting process parameters, appropriately reduce the injection speed and shorten the two-speed stroke;

3. Polishing the surface of the die-casting mold and carefully polishing the nitriding mold to prevent the surface nitriding layer from being damaged and sticking more and more;

4. Check whether the mold temperature is normal, and appropriately reduce the pouring temperature of alloy liquid and mold temperature;

5. Improve the design structure of the gating system to avoid the continuous erosion of the cavity wall or core by the alloy liquid;

6. Try to grind several transverse grooves on the moving die, 0.2-0.3mm is enough, and the die casting will show that it is very bright and will not be damaged. This can increase the clamping force on the side of the moving die and bring the die casting to the moving die.

The above is what Hangzhou EPC molding machine factory brings to you.
