Medical Zinc Alloy Die Casting
The Zinc Alloy Die Casting Process in Medical Manufacturing
Medical zinc alloy die casting uses special methods to make exact parts for medical tools. First, engineers design the part and prepare the mold. They use CAD models and build steel molds to fit the device’s needs. The die casting machine heats the mold and melts the zinc alloy, often using zamak. The hot metal is pushed into the mold under high pressure. This fills even tiny spaces in the mold. The metal cools and hardens, keeping the right shape for medical use. Workers open the mold and take out the zinc part. They cut off extra material. Then, they polish or plate the part to make it smooth and clean. Quality control teams check every piece to make sure it meets strict medical rules.
Note: Zamak alloys, like zamak 3, zamak 5, and zamak 7, are strong and resist rust. They also cast well. These alloys are good for surgical tools, diagnostic housings, and prosthetic parts.
