Brief Introduction

PCD is made by sintering micron-level diamond particles and binder under high temperature and high pressure conditions. It has the advantages of high hardness, good wear resistance, and strong impact resistance. The die has the advantages of uniform wear and long life during use. High speed drawing.
According to the different binders, PCD blank can be divided into cobalt-based and silicon-based. The cobalt-based PCD blank contains a metal binder and has good machinability. It can be processed by electric spark, laser, ultrasonic and other processes. However, the presence of metal cobalt makes diamond easy to graphitize at high temperatures, so this type of core Suitable for processing and use under the condition of less than 650 ℃. Silicon-based PCD blanks have relatively poor machinability, but there is no metal binder in the material, so the material can still maintain good thermal stability at 1000 ° C.
The polycrystalline diamond core and the cemented carbide support ring are tightly sintered into one, and the cemented carbide support series products can bear greater pulling force. They are mostly used to manufacture large-aperture mold blanks and draw wires with thicker diameters.
·Cobalt bond tungsten carbide supported die blanks is through the high temperature and high pressure process to sintering the gold steel stone powder the binding agent metal cobalt and the hard ring at one time into the drawing die core.
·Hard alloy ring supporting, better protection of drawing die core not deformation, extended service life, only applicable to circular drawing die blank.
Specification:

Product Advantage

·Can be used for wet and dry drawing applications.
·Available for almost any type of wire drawing operation, from rod-size to fine-size.
·It has high abrasion resistance, hardness and thermal conductivity, and has good mechanical strength and toughness.
·Extended service life.
·Polycrystalline diamond core and sintering cemented carbide support ring closely, tungsten carbide ring support, make it has better crack resistance, therefor this kind of product can withstand the high strength and high speed drawing.
