Packaging
- Rust Prevention Treatment: Our state-of-the-art rust prevention strategy involves treating the surfaces of cast steel parts with premium-grade rust inhibitors. This process forms an ultra-dense anti-rust coating, ensuring that all our precision casting carbon steel valves for industrial applications remain immaculate throughout their journey from our facility to your hands.
- Buffer Protection: We prioritize the protection of each component with exceptional care. Parts vulnerable to impacts are lovingly encased in high-quality buffer materials like foam boards and sponges. This thoughtful wrapping acts as a cushion against potential collision damage during transit, safeguarding the integrity of each piece.
- Outer Packaging: Our commitment to excellence extends to our packaging solutions. Smaller cast steel components are meticulously nestled within robust wooden boxes, with interiors packed securely to eliminate any possibility of movement during shipment. Larger items are firmly anchored within tailor-made metal or wooden frames. When needed, we utilize container transport to elevate security, ensuring every product arrives in pristine condition.

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.
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.
