MIM of high-performance widely used in various industries and products, including automotive, aerospace, defense, mobile phones, dental instruments, electronic radiator and seal packaging, electronic connectors, hardware, industrial tools, fiber optic connectors, spray system, disk drives, pharmaceutical equipment, portable power tools, surgical instruments and sports equipment..
Product with the following characteristics, generally suitable for MIM.
Complexity:MIM same as injection molding, any shape design. Because MIM is a molding process,additional features of the product does not increase the cost,which makes MIM ideal way to combine individual parts into a multi-functional product. Design rules of MIM and injection molding is very close, so it is easy to adapt to almost any product.
Precision: the MIM net forming precision of the reference design is typically ± 0.5%. Certain characteristics of net shape can reach ± 0.3%.As with other technologies, high-precision means higher costs, therefore encouraged to relax the tolerances.
MIM can not independently satisfy the tolerance may be achieved by various surface treatment processes.
Weight and size:Weight of less than 100 grams of parts suitable for MIM process, less than 50 grams is the most economical application. However, the weight of 250 grams of parts can also be dealt with. The cost of raw material is the key to the MIM process. MIM contributed innovative ways to minimize the weight of components. As well as plastic products, can under the condition of not affect the integrity of the product, by the kernel and stents to reduce the weight of the parts.The MIM performed very well in the tiny and tiny parts, weighing less than 0.1 g is also possible. Weight is not a limiting factor, length of more than 250 mm of products can be processed.
Thin: less than 6 mm wall thickness is the most suitable for MIM.
The outer wall can be thicker, but this would increase the cost. In addition, MIM can achieve less than 0.5 mm extremely thin-walled, but the design has a high dependence.
Production: the MIM is flexible process. From each year thousands of pieces of production to the production of millions of able to achieve very economy. Similar to casting or plastic parts,A set of mold and project investment is the MIM process necessary,for small batch of products, it will usually affect decisions.
Raw material: the MIM can deal with a lot of materials, including iron alloy, super alloy, titanium alloy, copper alloy, refractory metal, hard alloy, ceramic and metal matrix composites. Although non-ferrous alloy aluminium and copper is technically feasible, but usually by other cheaper ways of processing, such as die casting or machining.
