Fully Automatic 25T Hot Chamber Die Casting Machine for Zipper Heads

Built for zipper manufacturers that require strict dimensional accuracy and smooth surface quality, our 25-ton hot chamber die casting machine delivers consistent, burr-free zipper sliders and pull tabs across every batch, reducing polishing and post-processing labor. Optimized for zinc alloy injection, it eliminates the surface defects and fill inconsistencies common in lower-end casting machines for small zipper parts.

Running at over 10 cycles per minute, this 25T machine delivers 40% higher throughput than precision-focused competitors, so you don’t have to choose between surface finish and production speed. Its calibrated injection system delivers uniform fill for every cavity, preventing porosity and flash that mar zipper part surfaces.

• Precision metered injection delivers shot-to-shot consistency within tight tolerance ranges, meeting strict zipper industry quality standards for fit and surface finish.
• Uniform, smooth as-cast surfaces reduce manual polishing and deburring work, cutting labor costs per finished zipper part.

An exclusive, proprietary cooler design eliminates limescale buildup entirely, allowing the machine to maintain steady die temperature even in hard water regions — a critical factor for consistent zinc alloy flow and repeatable surface quality across every zipper part.

• Integrated oil cooling system maintains steady hydraulic pressure and temperature cycle after cycle, further improving shot-to-shot consistency for zipper sliders and pull tabs.
• Heavy-duty, wear-resistant construction optimized for zinc alloy processing supports a 10–15 year service life with standard routine maintenance.

We offer custom configuration options to match your precision zipper part production requirements:

• Supplementary cooling unit for enhanced temperature control with high-cavity complex zipper pull tab die geometries
• Precision injection upgrade kit for even tighter tolerance control and finer surface finish

We provide end-to-end support to ensure your machine maintains peak accuracy throughout its service life.

• 10-day express delivery for standard configurations, cutting lead times to get you into full production faster
• 2-hour initial response + 24-hour full resolution after-sales support for all technical issues
• 1-on-1 dedicated account manager service throughout your order and equipment service life
• On-site engineer service available for installation, precision calibration, operator training and scheduled maintenance
• Factory visits are warmly welcomed to inspect equipment and discuss your zipper production needs in person
