Diamond Drawing Dies

详情

Currently in drawing industry, polycrystalline drawing die more widely used, and the main reason is nothing more than the following three points: (1) polycrystalline drawing die species diversity, wide selectivity for customers. Polycrystalline drawing dies can be divided into three kinds of categories, a. Domestic polycrystalline drawing die, b. Gao Jing cd drawing dies, c. Imported polycrystalline drawing die. 2 polycrystalline drawing die price diversity, wide selectivity for customers. Three categories of polycrystalline drawing die to cheap price by the order is: imported polycrystalline drawing dies, high crystal cd drawing dies, wire drawing dies three domestic polycrystalline polycrystalline drawing die life and finish than the tungsten steel ideals, is an alternative ideal for tungsten steel. Imported polycrystalline diamond powder in the mold is made ​​of silicon metal catalyst role, the use of high-pressure, high-temperature sintering process. Under strict process control conditions, the diamond particles are formed between the diamond crystallites health binding, making it similar to natural diamond having a high hardness and high thermal conductivity, and because diamond powder is irregular arrangement, so that the performance of polycrystalline diamond isotropic, regardless of its orientation during processing, and has better toughness and wear resistance. Polycrystalline module is mainly divided into three categories: domestic polycrystalline, CD mode or high grain mold, mold-made imported polycrystalline silicon polycrystalline diamond polycrystalline module is, in addition to lower prices, its physical characteristics and product stability and imported poly Polycrystalline diamond and cobalt-based domestic polycrystalline diamond has a larger gap. Die size range: 0.*0mm ~ 8.*0mm, also known as a highly crystalline drawing die CD mode, it is more the hardness and density, the degree of crystallinity and more uniform, and a more rational arrangement of the molecules based on synthetic polycrystalline. Reducing the grain out and roughness. The product is in high grain, high production, and therefore temperature up to ***0 ° C, is a better alternative to imported polycrystalline product, it is not only natural diamond abrasion resistance and hardness, but also has good roundness, It's fine crystalline particles provide higher brightness to see the finished wire. Imported polycrystalline diamond is diamond powder in a metal catalyst (cobalt) role, using high-pressure, high-temperature sintering process. Under strict process control conditions, the diamond particles are formed between the diamond crystallites health combined so as to have high hardness similar to natural diamond, high thermal conductivity, and because diamond powder is irregular arrangement, so that the performance of polycrystalline diamond Each of the communication, processing regardless of its orientation, and possessed better toughness and wear resistance.
