Zinc alloy is heated to a liquid state in a melting furnace and injected into the mold cavity under high pressure. After cooling, it forms blanks of hardware parts (such as buckle bodies, lock parts, and bases).
The control panel integrated on the equipment allows settings for pressure, temperature, and injection speed to ensure full forming and stable dimensions of parts. It is the main equipment for mass production of luggage hardware.
Aluminum / zinc scraps at the discharge outlet, as well as sprues and gate wastes generated during die-casting, can be recycled and remelted for reuse.
🏭 Complete Process of the Die Casting Workshop
Raw Material Preparation: Zinc alloy ingots (or aluminum alloy) are put into the melting furnace, heated to liquid, and kept warm for use.
Die Casting: The die-casting machine injects molten metal into the mold under high pressure, keeps pressure, and cools to form part blanks.
Part Removal & Trimming: After mold opening, blanks are taken out, and sprues, material heads, and flash are removed.
Post-treatment & Transfer: Blanks are simply polished to remove parting lines and burrs, then sent to the polishing workshop for surface treatment.
