The cold head dies are subjected to a strong stamping load, and the surface of the concave dies is highly compressed, requiring the material of the die to have high strength, toughness, and wear resistance, so the production process and process of the cold die directly affect the quality of the dies.
UKO has many years of tungsten carbide dies manufacturing experience, has accumulated rich technology, from raw materials from tungsten carbide powder to the final product, with a complete set of reasonable, rigorous production technology and quality control processes.
- Quality Testing
The cold head cold dies is mainly used in: a variety of metals and non-metallic powders, stamping, steel rods, steel pipe stretching, large stress, working, perforation and stamping mold, machine accessories, Core, making stamping mold, such as stamping watch parts, musical instrument spring, etc.
Dies the battery case, toothpaste skin; small size steel ball, screw, nut stamping mold, impact forging dies and manufacturing standard parts, bearings, tools, etc. Cold punching, cold press dies; warheads and Stamping dies of the shell.
