Compared
with tungsten carbide, PCD wire drawing die has good wear resistance, uniform
abrasion of inner hole, strong shock resistance, high drawing efficiency, the
price is much cheaper than natural diamond die, and can reach big diameter. It
is widely used in drawing industry.
跟合金模具相比，聚晶金刚石拉丝模具具有更好的耐磨性，更光滑的内控，更好的耐冲击力，更高的效率，价格比天然金刚石模具低，而且能做相对大的孔径。它被更广泛地用于拉丝行业。
