Fully Automatic Hot-Chamber Die Casting Machine: Operating Principle
This machine is an integrated hot-chamber die-casting system, combining a melt furnace and an injection unit in a single design. The injection structure remains immersed in the zinc alloy melt for extended periods.
During operation, the equipment automatically performs the full cycle, including mold closing, high-pressure injection, pressure-hold cooling, mold opening, and ejection of finished parts. Molten zinc alloy is injected into the mold cavity at high speed through a gooseneck tube. After cooling and solidification, it forms a precisely shaped zipper head, eliminating the need to manually transfer molten metal throughout the process.
As an upstream unit in the zipper production line, this model delivers consistent, standardized zinc alloy zipper head blanks. It seamlessly interfaces with downstream equipment for zipper webbing feeding, tooth arrangement, zipper-head threading, surface finishing, and related processes, forming a complete automated zipper production system.
