The production and manufacture of cemented carbide tools include three key whole processes of mixture preparation, forming and sintering. In order to make the aluminum alloy have the necessary compressive strength and strength, the bonding metal material is added to the cementite in fine powder form, and other components are added when necessary. These types of raw materials are milled by a ball mill or rod mill for a certain period of time to make a homogeneous mixture with a certain prescribed particle size distribution. Milling is generally carried out in aqueous solutions of organic chemicals such as ethanol and hexane. In addition to the mixture used for pressing, a forming agent (such as paraffin) must be added to the mixture. The slurry obtained by grinding can be used in different drying methods (such as spray dryer) to better remove organic chemical liquids.

Cold extrusion is the most common forming method. It is the whole process of processing the mixture into a compact with a certain relative density, compressive strength, shape and size. Use the abrasive tool to make the final product look, and fully consider the size of the sintering. Therefore, the size of the abrasive tool should exceed the size of the final product. To ensure the uniformity of the density of each position of the compact, without layers, cracks, and uncompacted conditions, is the technical importance of press forming. Production and manufacturing often choose double pressing or multi-directional pressing.
