MIM sintering problem

Sintering problem caused by one of the most important direct consequence is to make the product size change and affect the final size of the product accuracy, in the early days of the MIM technology development, the deformation and dimension precision of products is not high, once become the key factor of the MIM technology industrialization, the MIM a process with the final when sintering, the density will produce large volume shrinkage, dimension change is very big, sintering the need for performance, need to control the density of sintered body, magazine content and organization, and its composition, density change is bound to affect the size and dimension precision of products.
