What is Zinc Die Casting？
Zinc die casting is a high-precision metal forming process where molten zinc alloy is injected into a steel mold under high pressure to create complex, durable parts with excellent surface finish.
How Does Zinc Die Casting Work?
Using the hot chamber method, molten zinc is drawn directly into the injection system, enabling fast cycle times and high efficiency—ideal for producing small to medium-sized components at scale.
Key advantages:
precise, strong, and cost-effective solutions for high-volume small and medium-sized parts.
