In understanding the process of powder metallurgy technology, guangdong big macro new materials exposed to the metal powder injection molding process, didn't think it is quite different from common molding technology, the mass production with complex geometrical shape, high performance, high precision of MIM ceramic casing, MIM smart apparel, MIM communications, medical, powder metallurgy micro gear, powder metallurgy small module gear and other aspects of complex precision components without any difficulty, prompting the guangdong big macro a breakthrough of the industrialization of the new material.


In addition to preparing the corresponding powder for processing, more binder should be added to the powder for injection molding of guangdong dahong new material. Therefore, both the powder and the binder should meet the requirements, otherwise it will affect the forming of powder metallurgy products. Guangdong macro new material of MIM experts in metal powder injection molding process of understanding to the metal powder injection molding powder need 10 or less um nearly spherical ultrafine powder, and the mixed expect defatted sintering, process is relatively complicated, the craft is strict, especially need longer debinding and sintering time, which is caused by the guangdong big macro new materials to make the main reason for the higher cost. And the amount of binder must be sufficient, otherwise it is difficult to achieve the corresponding performance.


A simplified method has been developed for this by guangdong da-hong new material, which is the flow temperature molding technology. It combines the advantages of metal powder injection molding technology on the basis of metal powder warm pressure. Then the fluidity, filling and molding of the mixed powder are greatly improved by adding appropriate amount of coarse powder and fine powder and increasing the content of thermoplastic lubricant. Because the powder is mixed into a viscous fluid with good fluidity when pressed, it not only has the advantage of liquid, but also has high viscosity and reduces the friction force, so that the pressing pressure can be distributed evenly in the powder and it can be transmitted well. As a result of this, the powder can flow to all corners in the process of compaction without cracking, which greatly improves the density.


At present, guangdong dahong new material has promoted this technology to be used for the very complex workpiece of the precision moulding shape on the traditional tablet press, which not only overcomes the deficiency of the traditional cold pressing in the forming of complex geometric shape, but also avoids the high cost of the metal powder injection molding technology.
