Product Description

It is a new technology for precision metal parts producing, can do any design according to your drawing. 
 
What Is MIM? 
Metal injection molding-MIM-offers a manufacturing capability for producing complex shapes in large quantities. The process utilizes fine metal powders (typically less than *0 micrometers) which are custom formulated with a binder (various thermoplastics, waxes, and other materials) into a feedstock which is granulated and then fed into a cavity (or multiple cavities) of a conventional injection molding machine. After the "green" component is removed, most of the binder is extracted by thermal or solvent processing and the rest is removed as the component is sintered (solid-state diffused) in a controlled-atmosphere furnace.
 
The advantages of the metal injection molding process lie in its capability to produce mechanical properties nearly equivalent to wrought materials, while being a net-shape process technology with good dimensional tolerance control. Metal injection molded parts offer a nearly unlimited shape and geometric-feature capability, with high production rates possible through the use of multi-cavity tooling.
 
MIM and PM Microstructure Comparison
The particle diameter of MIM material powder is much smaller than the traditional PM material powder, thus the density of MIM products is high. And the flexible shaping of MIM products cannot be achieved through traditional PM.

MIM and Traditional Machining Comparison
By right of automatization, traditional machining has improved in efficiency and precision, but its basic procedure is still step by step process (turning, shaving, milling, grinding, drilling, polishing, etc.). The precision of machining is superior to other processing procedures, but machining cannot efficiently use materials and the product size is subject to equipment and cutting tools, so that some components cannot be made with machining. On the contrary, MIM can put materials into full use and make various shapes. And MIM is more competitive to make components in small size and complicated shape because of its low cost and high efficiency.
   
Property of material: 
MIM process is highly versatile in material selections, Tool Steel, Alloy Steel, Copper Alloy, Tungsten Carbide, Titanium and other Special Alloy can be applied in MIM production.
