Method For Forming Cemented Carbide Rods

Cemented carbide rods are widely used in metal processing, electronics industry, wood processing, aerospace industry and medicine because of their special wear resistance, high hardness, excellent fracture toughness and compressive strength. Ideal pre-material for printed circuit board micro drills, milling cutters, reamers, step cutters, long rod cutters, taps and dot matrix printer pins, etc. With the development of science and technology, the demand for cemented carbide rods is increasing, and the forming technology has developed from traditional processes such as cold isostatic pressing and molding to more modern and economical extrusion forming processes, and the quality is getting better and better. There are more and more varieties.
Traditional processes can be divided into processes such as cold isostatic and molding. It is easy to produce "cracks" when forming bars with traditional processes, and the forming cost is quite high. Therefore, cemented carbide formers are trying to find a more economical and better quality process. Therefore, cemented carbide formers are trying to find a more economical and better quality process. Most of the rods are now extruded.
To sum up, cold isostatic pressing and molding are traditional processes for forming cemented carbide rods, which are generally only used for special occasions. Compared with the traditional process of cold isostatic pressing and molding, the powder extrusion molding (PEM) process has the advantages of low cost and high forming efficiency. It has become the most important method for forming cemented carbide rods and has broad development prospects. But at present, there is a big gap between our country and developed countries. We should make greater efforts in the research of the basic theory of extrusion rheology, the development of new molding agent systems, the research of molding technology and equipment supporting technology, so as to produce products with excellent performance. Cemented carbide rods for high-tech industries.
