RHD PCD polycrystalline Drawing mandrel

Co-based PCD wire drawing die core product compared with similar domestic products, more uniform and dense microstructure, and rarely appears similar products in the abnormal grain growth or "hold together" phenomenon, and therefore easier to grind holes and polishing, finish is also higher, and thus extend the life of the mold drawing. To this end, a large number of overseas companies to purchase our core 5 micron fine-grained, high hardness specially made stainless steel wire drawing dies.

In order to adapt to different customer needs, our CXD mandrel into the preferred level (CXD-A) and the general level (CXD-B) two kinds.
A high stability rating PCD drawing mandrel having equal or exceed imports mandrel beyond doubt, and import the same size core substantially uniform and high-quality finish equal size near the inlet of the mold core long life, the main supply of the production process is stable and reliable, high quality requirements of the manufacturers, some foreign manufacturers have been used to replace international first-class core products.
B grade PCD drawing mandrel mainly supply the production process (particularly inlay, drilling process) is not advanced enough, mainly the pursuit of low-cost factory, its quality and no price competition, becoming the domestic terminal the core of the most competitive products.
