Bronze Tungsten Steel Punch Set | Thermally Stable Constant Gap Die

Ordinary bronze-steel punch and sleeve assemblies suffer from significant fit gap drift due to mismatched thermal expansion

coefficients, causing burrs, dimensional deviations and even die jams when workshop temperatures fluctuate. This issue is particularly severe in production environments with large day-night temperature differences. Our Bronze sleeve and tungsten steel punch solves this thermal instability problem through precise material matching and optimized bonding processes.

We use specially formulated tin bronze sleeves and high-toughness tungsten steel punches with closely matched thermal expansion coefficients, ensuring the fit gap remains within design tolerances across a working temperature range of -10°C to 60°C. The thermal press interference bonding process creates a seamless, gap-free connection between the two materials, eliminating delamination risks. We also manufacture matching Hard alloy Lower die sleeve and Hard alloy supporting mold with the same material matching standards for consistent thermal stability across the entire die system.

As a professional manufacturer of Precision Mechanical Parts, we can customize assemblies with different material ratios based on your actual operating temperature and stamping speed. In addition to the bronze-tungsten steel punch series, we also produce Tungsten Steel Firing Pin, Hard Alloy Punching Needle and various non-standard carbide die accessories to meet diverse industry needs.
