In the process of using the die-casting mold, we need to understand the surface condition of the die-casting mold, which has a great influence on the use of the die-casting mold, so what is the specific situation?
1. The surface defects of most products, especially those close to the gate, are caused by the injection speed.
2. Multi-stage injection can only be used when one injection cannot meet the technological requirements, especially in the experimental stage.
3. When the mold is in good condition, the inflection point is set correctly, and the injection speed is sufficient, the injection speed has no direct relationship with flash.
