Tungsten alloy parts

Tungsten alloy features

1, Suitable for highly complex geometric shapes
2, Most parts require little or no secondary machining process
3, High level of surface finish as processed, of 32 rms or better
4, Tight tolerances of up to forms complex metal shapes without the need for machining.

The tungsten alloy part adopts the technology of metal injection molding (MIM).

Metal injection molding offers a manufacturing capability for producing complex shapes in large quantities. The process utilizes fine metal powders (typically less than 20 micrometers) which are custom formulated with a binder (various thermoplastics, waxes, and other materials) into a feedstock which is granulated and then fed into 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 MIM process is very similar to plastic injection molding and high-pressure die casting, and it can produce much the same shapes and configuration features. However, it is limited to relatively small, highly complex parts that otherwise would require extensive finish machining or assembly operations if made by any other metal forming process.
Any small shape which can be envisioned as a plastic molded part is now available to the designer in a variety of standard or custom metal formulations through his net shape forming process. Material properties can be specifically tailored to meet non-standard requirements.
