Metal Injection Molding for the Medical Industry

Metal Injection Molding (MIM)

Metal injection molding (MIM) is a process used to manufacture complex, high-precision metal parts, freeing designers from the traditional limitations of molding stainless steel, nickel iron, copper, titanium and other metals. The molding process combines metal powder, injection molding and sintering technology to ensure that MIM parts have tight tolerances and excellent surface quality.

High-Precision Metal Injection Molding Parts for the Optical Industry

Optical Industry

Metal powder metallurgy is suitable for the manufacture of structural parts or auxiliary parts of optical parts, such as brackets, housings and heat dissipation components, but it is not suitable for the direct production of optical reflective or transmissive surfaces. For the production of optical core components, other processes (such as glass molding or precision cutting) are usually required.

Using specific metal powders (such as stainless steel, titanium alloy, etc.), MIM can achieve the strength, lightness and corrosion resistance required by optical devices.

Advanced Metal Components for the Semiconductor Industry

Semicon Industry

MIM can produce small parts with complex shapes, and is particularly suitable for structural parts such as brackets, fixtures, and housings in semiconductor equipment, which usually have precise geometry and high strength requirements. It is also suitable for mass production and cost-effective for standardized parts in the semiconductor industry.

However, semiconductor parts usually require extremely low surface roughness (such as Ra 0.1~0.2μm) to prevent particle contamination. MIM parts require subsequent polishing or surface treatment to meet this requirement, which may increase costs.

High-quality supplier of metal powder metallurgy to the automotive industry

Automotive Industry

Although CNC machining and die-casting still dominate the automotive industry, metal powder metallurgy (MIM) processes often have advantages for many small and complex parts. For example, key components such as remote control keys, blades, valves, connecting rods, valve guides and parking brakes are more suitable for manufacturing through MIM processes to achieve lightweight, complex geometry and excellent mechanical properties.

The high efficiency and quality stability of the MIM process in mass production enable it to meet the automotive industry's stringent requirements for high precision, high strength and wear resistance. With its flexible adaptability to various alloys and customized formulations, MIM provides manufacturers with greater design freedom, helping innovative parts quickly pass the production part approval process (PPAP) and accelerate the development and launch of new models.
