TianGengLan Environmental Protection Technology Co., Ltd. is a precision wire-drawing machine manufacturer, specializing in the production of small-scale precision drawing machines, roller dies, WN drawing machines, and precision rolling mills. We independently develop spring steel wire square wire, flat wire precision drawing machines, coiling spring continuous rolling production lines, valve spring special-shaped wire drawing machines, and triangular wire drawing machines to replace imported cold rolling machines from Europe, America, and Japan. Our innovative rolling process combined with roller die stretching technology significantly reduces the mold and production costs of traditional methods. The products produced have a high surface finish, with straightness up to 0.5mm/m and thickness accuracy within 0.005mm, and width tolerance within 0.005mm.

Introducing the high-precision, miniature precision roller grinding technology from Japan, the precision rollers we produce have a true roundness tolerance less than 0.001mm. The surface finish is Ra0.02μm.

Service Commitment: We offer not just equipment, but also processes, technology, and services. We provide free sample making and die design for non-standard wire materials to our users.
