High wear-resistant cold work die steel is generally high carbon high chromium steel, representative steel grades are: Cr12, Cr12MoV, Cr12Mo1V1, Cr12W, Cr12V, LD (7Cr7Mo2V2Si), ER5 (Cr8MoWV3Si), GM (9Cr6-W3Mo2V2) and so on. ...
ccording to the editor of diecastingcompany.com, the cost of tools is 8-15% of the total cost of products. In fact, if you consider the time required to replace worn tools and the loss caused by accidental failure, the cost may be as high as 30% to 50%. Moreover, the wear of the tool will cause a si ...
SWRCH22A is a kind of hot-rolled non-twist and controlled cooling wire rod. Mainly used to manufacture standard fasteners such as bolts, screws, studs, nuts, rivets and self-tapping screws. The quality problems that are prone to occur during the manufacturing process are: breakage during the drawing ...
In the continuous casting process, molten steel undergoes a series of phase transformation, crystallization and other processes, especially when the carbon content of the steel is in the peritectic reaction zone, due to the occurrence of the peritectic reaction, the liquid phase and the delta phase ...
Free forging refers to the processing method of forgings that use simple general-purpose tools or directly apply external force to the blank between the upper and lower anvils of the forging equipment to deform the blank to obtain the required geometric shape and internal quality. The forgings produ ...
The hot extrusion method is also a common process in forging processing. This process is mainly used to manufacture long parts, rods, tubes, profiles, etc. with ordinary cross-sections. These extruded parts can be used directly as structural parts or after cutting. ...
The method of contacting steel with a high-speed rotating grinding wheel and determining the chemical composition of the steel approximately according to the shape and color of the spark produced by grinding is called the spark identification method. ...
Metal matrix composites are multiphase materials with a special second phase dispersed in a metal or alloy matrix. The second phase with special physical and mechanical properties greatly enhances the strength, hardness, wear resistance, heat resistance and other properties of the material. Therefor ...
The function of die-casting release agent is to improve the production efficiency of castings and product quality, while minimizing the negative impact of workplace and wastewater discharge on the environment ...
At present, in mold manufacturing, new technologies such as electric discharge machining, form grinding, wire cutting, etc. have been applied to better solve the problems of complex mold processing and heat treatment deformation. However, these new processes have not yet been widely used due to vari ...
