Application of metal powder injection molding technology in special fields

Metal powder injection molding MIM technology can make use of rapid molding and sintering ware manufacturing high density, high precision, high strength, the precise structure of 3 d complex shape parts, especially some complex or difficult to processing of small parts, often the process can process some characteristics to features of products, to make up for some of the pitfalls of before. Metal powder injection molding technology can also be used in some special areas, the following large new materials small make up to give you a brief introduction.

1. Complex shapes. Allows free design of 3d shapes like injection molding. Since MIM technology is a molding process, additional product shapes will not increase the cost, and if weight reduction is achieved through shape design, the cost will decrease, making this process one of the ideal ways to combine more than one independent part into multi-functional parts.

2. Precise size. The precision of near net forming is usually ±0.5% of the size, and some dimensional features can be up to ±0.3%. As with other technologies, high precision means higher cost, so it is recommended that the dimensional tolerance be relaxed when it can meet the requirements of use. Tolerances that cannot be met directly can be achieved through subsequent machining.

3. Thin-walled products. Wall thickness of less than 6 mm is suitable. Thicker outer walls are ok, but MIM technology will increase the process time and material cost. Thin wall less than 0.5 mm can also be achieved by this process, and products with extremely thin wall of 0.2mm can be achieved (but there is a certain dependence on the specific product shape).

Since MIM process does not melt materials in the production process of MIM materials, it is not afraid to mix with impurities brought by crucible and deoxidizer, etc., and sintering is generally carried out in vacuum and reduction atmosphere, which is not afraid of oxidation and will not pollute MIM materials, so it is possible to produce high-purity materials.

The above is about the application of metal powder injection molding MIM technology in some special fields, I hope it can help you. If you want to know more about MIM technology of metal powder forming, you can pay attention to daewoo new materials.
