What are the methods to improve die-casting sticking mold?
Sticking mold is a common defect in the production of die casting products, which will cause many quality issues on the product, so when we meet this defect, how to solve this problem?
1. Adjust the die casting process parameters
The setting of parameters has a great influence on the sticking mold issue, such as injection pressure, injection speed, mold temperature, etc. and reasonable process parameter of the die casting machine can be set according to the structure and application of the die casting products.
2. Improvement of the gating system
The modification of the gating system of the die casting mold can prevent the pressure of the alloy liquid applied on the mold cavity and core. Change the size and position of the gate to increase the flow rate of the melted metal material.
3. Temperature control of metal materials
It is easy to meet sticking mold defects when the processing temperature is higher. The sticking mold defects can be well controlled by adjusting the temperature within a reasonable range through the equipment. At the same time, set a suitable processing temperature by the properties of the die casting material and products to avoid sticking mold defects.
4. Surface treatment of die casting mold
Reasonable mold treatment can avoid mold sticking defects, and special materials can be applied on the surface of the mold cavity and core.
5. Others
Adjust the spray positions and amount; check the hardness of the mold material and use heat-treated material for processing molds. Increase mold cooling cycle, etc.
