Fully Automatic Hot Chamber Die Casting Machine Working Principle
This machine features an integrated hot chamber die-casting design that combines the melt furnace and injection system into a single, compact unit. The injection mechanism is immersed directly in molten zinc alloy for sustained periods, ensuring consistent thermal conditions.
During automatic operation, the equipment executes a complete cycle: mold closing, high-pressure injection, pressure holding for cooling, mold opening, and final ejection of finished zipper sliders. The gooseneck tube forces liquid zinc alloy into the mold cavity at high speed, where it cools and solidifies into precisely shaped zipper head components without the need for manual metal transfer throughout the entire process.
As a critical upstream element in the zipper production line, this die-casting machine reliably outputs standardized zinc alloy zipper head blanks. It integrates seamlessly with downstream equipment — including zipper webbing machines, tooth arrangement systems, slider threading units, and surface treatment lines — enabling a fully automated and efficient zipper manufacturing system.
