What makes metal injection molded MIM parts better?
Powder metallurgy metal injection molding (MIM) is a precision molding optimization technology recognized by the industry. It can mass produce complex metal parts, ceramic parts and special materials to help the rapid development of the industry and various fields. Metal injection molding (MIM) parts, if assisted by gas, can improve the performance of metal parts. What can make MIM injection molding better?

1、 The Role of Gas in MIM Injection Molding
1: Can replace existing large metal parts
Gas can help improve the performance of MIM injection molded parts. For large parts and panels, another attractive feature is that heat conversion can be carried out and the vacuum molding or pressure molding parts can be replaced to avoid secondary molding and operation.

2: Control cost
Due to the reduction of space, a third of the clamping force is usually required, and compared with traditional MIM injection molding, parts of the same size can produce lower tonnage. The press not only keeps part of the cost control, but also introduces parts with small residual stress to further maintain dimensional stability. When the die is worn down, the pressure in the die is reduced, which allows the use of cheaper dies, and also greatly reduces the weight, thereby reducing the transportation cost and improving the efficiency.
3: Better stability and surface quality
When using gas assisted MIM injection molding, the parts produced have different wall thicknesses, and can be molded into a single part with more strict tolerance, or multiple parts. The supported part can be the molded part itself, and the gas channel can directly eliminate the residual part. Better dimensional stability and higher surface quality without additional steps.
2: Tolerance of MIM parts for metal injection molding
When MIM is used to manufacture parts by metal injection molding, its size range is close to 1 inch. This is a general reflection technology. It needs to be adjusted to the average size of central production during processing, which will be different. Therefore, it can be kept in a lower tolerance range, and smaller tolerance range can be achieved through finishing.
Gas assisted metal color injection molding (MIM) can better improve the performance and production efficiency of precision parts, and make precision parts have better dimensional stability and surface performance, but metal injection molding (MIM) should also be carried out in the production process. Considering the tolerance problem, in order to ensure the accuracy of metal parts, MIM injection molding has manufactured precision parts in various fields.
