FAQ

1, Casting process optimization category
Q: How to solve the problem of cracking in thin-walled die-casting products?
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?
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.
Q: Is there intermittent discharge during material feeding?
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.
3, Materials and Surface Treatment
Q: Does the casting have pattern defects after anodizing?
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)
4, Mold maintenance category
Q: What should I do if the mold frequently sticks to the material?
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
