25T Hot Chamber Die Casting Machine for Zipper Slider Zamak Pull Tab Machine

Designed to scale zipper slider and pull tab output without compromising dimensional consistency, this 25-ton hot chamber die caster runs at over 10 shots per minute — delivering 40% more throughput than standard same-tonnage models, making it an ideal match for high-cavity zipper part mold assemblies.

• Optimized injection system is calibrated for small, dense zipper part molds, ensuring uniform fill across every cavity and minimizing flash to reduce post-processing labor.
• Consistent injection precision guarantees uniform weight and dimensional accuracy across full bulk batches, lowering scrap rates and rework costs for zipper manufacturers.

A patented, exclusive cooling system design prevents mineral scale buildup entirely, enabling the machine to run smoothly even in hard water regions where standard casting equipment faces frequent clogging, cooling malfunctions and performance drops during round-the-clock zinc alloy zipper part casting.

• A built-in hydraulic oil cooling system keeps fluid temperature stable during extended continuous runs, reduces wear on core components and prolongs the machine’s overall service lifespan.
• Heavy-duty, wear-resistant construction calibrated for zinc alloy processing supports a 10–15 year service life with standard scheduled maintenance.

We provide flexible add-on upgrades to adapt the 25t hot chamber die caster to your unique zipper slider and pull tab production requirements:

• Additional auxiliary cooling unit for improved temperature regulation with complex, high-cavity zipper part mold designs
• Customized injection parameter tuning to match specific zinc alloy formulas and zipper part geometries
