Wax injection has a cape and injection is not enough

Cause of wax injection with cloak and injection is not enough:

Hello, glad to answer your injection molding industry questions.

This problem you mentioned is also a common problem in the injection molding process. There are many reasons for this problem. I don't know how long you call a short shutdown. For example, the chiller is very effective, if your cold runner mold stops, then the temperature drops very quickly, and the material shot in will affect the fluidity very much. The same goes for hot runner molds. For example, if you use a material like ABS, if your process is just at the molding threshold, then the problem will occur if you shut down for a while. Another example is that the mold doesn't vent very well, and after a shutdown, the mold will also not be hitting the surface when it's cold. Finally, it is recommended that you exit the injection table, manual injection, experience to see whether the injection nozzle mouth is normal and so on. So, we usually injection molding process is adjusted, the normal playing products, injection pressure is relatively molding critical value of a little higher, but to ensure that there is no flying edge, cloak. I hope to be able to help you. More injection molding problems, please ask questions. Buy injection molding machine, please consult!
