FAQ

1. Casting process optimization category
Q: How to solve the problem of cracking in thin-walled die-casting products?
A: Suggest controlling the proportion of recycled materials to ≤ 30%, calculating the mold retention time based on a wall thickness of 1mm/3s, controlling the ejection delay within 0.5-2 seconds, and optimizing the mold cooling system.

2. Equipment and operation category
Q: How to handle emergency situations when the injection head is stuck in the goose neck area?
A: After the equipment cools down, try rotating the hammer head. If it cannot be rotated, replace the driver cylinder; Long term solution: It is recommended to upgrade the material of the material pot and regularly clean impurities.

3. Q: Is there intermittent discharge during material feeding?
A: Check if the nozzle is blocked (the gray section indicates blockage), which can increase the nozzle temperature by 5-10 ºC, shorten the nozzle departure time by 0.1-0.2 seconds, and moderately reduce the flow rate of the fixed mold cooling water.

4. Materials and Surface Treatment
Q: Does the casting have pattern defects after anodizing?
A: Adjust the uniformity of injection oil spraying and optimize the high-speed injection switching position; Regularly check the copper ion concentration in the oxidation tank (recommended ≤ 20ppm)
5. Mold maintenance category
Q: What should I do if the mold frequently sticks to the material?
A: Comprehensive solution: Reduce pouring temperature by 20-30 ºC Use polymer release agent Polish the surface of the mold cavity (use with caution for nitriding molds) Optimize sprue design to reduce metal liquid flushing
