With the continuous tightening of global environmental protection policies, the die casting industry is accelerating its transformation towards green and low-carbon development. Environmentally friendly die casting processes (such as chrome-free passivation, water-based spraying, etc.) are gradually replacing traditional high-pollution processes, which not only reduces the environmental impact during production, but also improves product competitiveness. Our company actively responds to environmental protection calls and has fully promoted environmentally friendly surface treatment processes to achieve coordinated development of production and environmental protection.
