Metal Injection Molding Process

Metal Injection Molding (MIM) is an effective way to produce complex and precision-shaped parts from a variety of materials. This process produces parts for 50% less than the cost of CNC machining or casting. MIM is able to produce parts with complex shapes, superior strength and excellent surface finish with high volume manufacturing.

Benefits of Metal Injection Molding (MIM) With FacFox

MIM offers greater design freedom than many other production processes by freeing designers from the traditional constraints associated with trying to shape stainless steel, copper, titanium, and other metals. Other benefits of MIM, include:

  • MIM makes it possible to integrate and consolidate several components into a single molded piece—reducing the need to work with several manufacturers and decreasing processing and assembly costs.
  • Texture, knurling, threads, lettering, and company logos can all be incorporated into the mold.
  • At FacFox, we also provide fast prototyping service for metal products with DMLS metal 3D Printing, validate your design before investing big in molds!

Metal Injection Molding (MIM) Processes

Compound & Molding

A special polymer and metal blended feedstock is injection molded and we get a so called “green part”.

Debinding

The “green part” is then put through a controlled process called debinding that removes the binder. Once the debinding is complete, the component is referred to as “brown”.

Sintering

During sintering temperatures reach near the melting point of the material. Sintering eliminates the remaining binder and gives the part its final density and strength.

Available Finishes

The finish option with the quickest turnaround.

Parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request. Surface finish is comparable to 125 uin Ra finish.

Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized.

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in coating and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusionsdrum hardware and automobile and bicycle parts.
