Raw materials that can be processed by MIM process of metal injection molding

Although the precision and complexity of the precision casting process have improved in recent years, it is still inferior to the dewaxing process and the MIM process. Powder forging is an important development and has been applied to the mass production of connecting rods. However, in general, there are still problems with the cost of heat treatment and the life of the die in the forging project, which still need to be further solved. The traditional mechanical processing method, which has recently improved its processing ability

byautomation, has made great progress in effect and accuracy, but the basic procedure is still inseparable from the way of gradually processing (turning, planing, milling, grinding, drilling, polishing, etc.) to complete the shape of the part. The machining accuracy of the machining method is far better than that of other machining methods, but because the effective utilization rate of materials is low, and the completion of its shape is limited by equipment and tools, and some parts cannot be machined. On the contrary, metal injection molding MIM can effectively use materials without restrictions. Compared with mechanical processing, metal injection molding MIM technology has low cost and high efficiency, and has strong competitiveness for the manufacturing of small and difficult shape precision parts. Metal injection molding MIM technology does not compete with traditional processing methods, but makes up for the technical deficiencies or the inability to make defects of traditional processing methods. Metal injection molding (MIM) technology can play its advantages in the field of parts made by traditional processing methods.

Metal injection molding MIM process has the technical advantages in parts manufacturing, which can form highly complex structural parts.

The spray forming technology uses the jet machine to spray the product blank to ensure that the material is fully filled with the mold cavity, which also ensures the realization of the high complex structure of the part. In the past, in the traditional processing technology, individual components were made first and then assembled into components. When using metal injection molding MIM technology, it can be considered to integrate into a complete single part, which greatly reduces the steps and simplifies the processing procedure. Compared with other metal processing methods, metal injection molding MIM has high dimensional accuracy of products. It is not necessary to carry out secondary processing or only a small amount of finishing spray molding process to directly form thin-walled and complex structural parts. The shape of products has been close to the final product requirements, and the dimensional tolerance of parts is generally maintained within ± 0.1 - ± 0.3. In particular, it is of great significance to reduce the processing cost of cemented carbide which is difficult to machine and reduce the processing loss of precious metals.
