15-year precision mould making

Today, I will mainly analyze the tungsten carbide mold parts performances for you. It can be divided into 6 performances. Dongguan Yize Mould is a professional manufacturer of tungsten carbide mold parts, so it is very familiar with this field.
1. Obdurability
The working conditions of most tungsten carbide mold parts machining are very bad. Some often bear the large impact load, which results in brittle fracture. In order to prevent tungsten carbide mold parts suddenly brittle fracture at work, they should have high strength and toughness. The obdurability mainly depends on the carbon content, grain size and organization of materials.
2.Fatigue fracture properties
     In the working process of tungsten carbide mold parts, under the long-term effects of cyclic stress, it often leads to fatigue fracture. Its forms include small energy repeated impact fatigue fracture, the tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. Fatigue fracture performance mainly depends on the strength, toughness, hardness, and the content of inclusions in the material.
   3. Abrasive resistance   
The abrasive resistance of materials is one of the most basic and important performances of tungsten carbide mold parts performances. Hardness is the main factor influencing the abrasion resistance. As a general rule, the higher the hardness of tungsten carbide mold parts, the smaller the abrasion, the better the abrasive resistance. In addition, abrasion resistance is also connected with the species, quantity, shape, size and distribution of carbide in the material.
Above is the former three necessary tungsten carbide mold parts performances. I will then update the rest later on.
