The 68 ton fully automatic hot chamber die casting machine is a core front-end equipment dedicated to zinc alloy zipper heads. With mature hot chamber die casting technology, it can fully automatically complete the entire process of melting, die casting, forming, and demolding of zinc alloy zipper heads,
The produced zipper heads can be directly connected to subsequent polishing, assembly, threading and other processes, and are key equipment for zipper manufacturing enterprises to achieve automation and large-scale production of metal accessories. They are widely suitable for the production of nylon zipper heads in clothing, luggage, shoes, hats, home textiles and other categories.
This machine belongs to an integrated hot chamber die-casting equipment, with an integrated design of the melt furnace and injection system. The injection structure is immersed in the zinc alloy melt for a long time.
During operation, the equipment automatically completes a series of actions such as mold closing, high-pressure injection, pressure holding cooling, mold opening, and ejection of finished products. Molten zinc alloy is injected into the mold cavity at high speed through a gooseneck tube, and after cooling and solidification, it forms a neatly shaped zipper head, without the need for manual transfer of molten metal throughout the entire process.
As an upstream equipment of the zipper production line, this model stably outputs standardized zinc alloy zipper head blanks, seamlessly connects with zipper webbing, tooth arrangement, threading zipper heads, surface treatment and other equipment, and builds a complete automated zipper production system.

Fully Automatic Operation, Lower Labor Costs
Equipped with a PLC control system and touchscreen interface, the machine supports fully automatic production and can integrate with automatic feeding and conveying systems. One operator can monitor multiple machines, significantly reducing labor costs and improving production efficiency.
High Casting Precision, Consistent Quality
Advanced pressure and speed control ensure precise zinc alloy filling, producing zipper sliders with accurate dimensions, smooth surfaces, and minimal defects. Low-pressure mold protection extends mold life and reduces maintenance costs.
Integrated Hot Chamber Design, Energy Efficient
The hot chamber system combines the melting furnace and injection unit, minimizing material oxidation and improving zinc alloy utilization. Fast cycle times, lower energy consumption, and continuous operation make it ideal for high-volume production.
Flexible Production for Various Designs
Supports customized molds for different zipper slider sizes, styles, logos, and special designs. Quick mold change enables efficient switching between mass production and customized orders while ensuring reliable machine performance.
Safe Operation & Easy Maintenance
Designed with multiple safety protection systems and a user-friendly touchscreen for simple operation. The optimized machine structure allows convenient cleaning and maintenance, reducing downtime and long-term operating costs.
This fully automatic hot chamber die-casting machine is dedicated to supporting zipper production lines and is the main equipment for producing zinc alloy zippers in zipper factories. The produced zipper heads can be used with various zippers such as clothing jackets, casual pants, bags, tents, bedding, etc,
It is suitable for supporting the full process automation assembly line of large zipper enterprises, and can also meet the independent production needs of small and medium-sized hardware and zipper processing factories for zipper heads.
The equipment can be flexibly matched with surrounding automation equipment according to the factory layout and production capacity requirements, to create an integrated zinc alloy zipper head die-casting production line.
