Electric Lock Complex Components

Feature：With the development of smart electric industry, more and more smart locks appear to the market. MIM play an important role in lock industry. Mixing material is the first step of MIM. Thus, choosing raw material decides the following process quality. 

The ideal MIM powder is: powder particle size 2 ~ 8μm; bulk density of 40% ~ 50%; tap density of 50% or more; powder particles near spherical, larger than the surface.

At present, MIM metal powder raw materials include iron, nickel, titanium, stainless steel, precious metals, super alloys and other materials, as well as to the diversification of development, such as structural materials, functional materials, magnetic materials etc.

The main methods for producing MIM powder are: carbonly, ultra-high pressure water atomization, high pressure gas atomization, plasma atomization and laminar flow atomization. Different powder preparation techniques have different effects on the particle size, particle shape, micro-structure, chemical properties, and manufacturing cost of the powder.

MIM technology can make various kinds of metal parts. If your part is made of stainless steel, steel, iron and the shape is complex, MIM is the best choice. If you want to make metal components by MIM, you need to send us the parts drawings, including PDF and 3D files in which, we can see the shape, sizes, tolerance and other requirements such as surface treatment, hardness(HRC). Also, we need to know the quantity for the part. Because to make MIM items, the mold is important. To make a mold is around 3000--5500USD that based on the shape, so if the customer have several parts to produce, we suggest to put them in one mold to save cost.
