The ceramic mold is made of nano-zirconia ceramic by special manufacturing, with high toughness, high strength, high hardness, high wear resistance, good self-lubricating, low thermal conductivity and excellent surface finish (Ra up to 0.01). Features such as um), as well as good high temperature performance and thermal shock resistance. Widely used in pipe making, wire making and cable industries, it not only improves the surface quality of the product, but also prolongs the life of the mold. It is the best substitute for traditional cast iron, steel, corundum and carbide molds. The main products are squeeze roller, reduce roller, three-wheel bending roller, guide ring / sleeve, scraper, hot extrusion die, wire drawing die, drawing die, guide wire wheel, tower wheel and so on.
