This is hicoo tungsten carbide products coltd The core of imported Poly Crystal dies is a kind of supper thin and average granule formed by high temperature and press and then crystallized, which can ensure the anti-round degree and high fineness surface, long drawing-wire life. It is hard to appear the phenomenon of mold abrade and flat wire in a long term in the drawing process. We recommend to produce finished-products mold of small, medium and large linear material, high speed wire-drawing mold, high compress rate mold, linear material with tight tolerance and high fineness degree mold. Averagely, its life is three or five times than diamond, two times than high crystal mold, ten or twenty times than hard alloy mold. It is easy to gain long term and bright wire material of stable dimensions The range of dimension is 0.20mm -8.00mm
