Leave metal heat treatment, including high-frequency hardening and distortion correction, to us.
Our company was founded in 1967 and specializes in high-frequency hardening, adhering to the motto of "high quality, short delivery times, and low cost." Among the various metal heat treatment processes, we have deepened our collaboration with specialized contractors over the years for overall hardening methods such as vacuum, carburizing, and salt hardening, as well as nitriding treatments like tuftriding and gas softening, and annealing shots. We are equipped to meet any needs related to heat treatment in general. ■ Dedicated to "High-Frequency Hardening" We handle products of special sizes, complex shapes, and even thin plate products that tend to warp significantly when heated—items that may be deemed unacceptable or for which we might receive refusals from others. We address these high-difficulty products with our own coils and the skilled techniques of our artisans. ■ Confident in Our Skills "Warp Correction" With over half a century of experience and achievements, we take pride in our ability to correct warping caused by hardening to a level of 0.1mm, skillfully manipulating pressing and heat as part of our high technical capabilities. ■ We Deliver "Short Delivery Times" Our ability to provide a consistent service from hardening and tempering to warp correction allows us to deliver on the same day as drop-off in the shortest possible time. We strive to meet our customers' deadlines to the fullest extent.
