MIM Parts

Metal injection molding (MIM) is a powder metal process that is characterized by forcing metallic feedstock under pressure into a tool cavity. This process is similar to the injection molding process but uses powder metal feedstock. The resulting ‘green’ part goes through a debind process followed by a sintering process to produce a high strength metal part. The tool cavity is created using two hardened tool steel dies which have been machined into shape. Most MIM parts are made from stainless steel alloys, but other exotic materials such as titanium are available.

What is a mim part?

A MIM Sintered parts manufactured by powder metal injection moulding with a certain degree of dimensional accuracy and capable of withstanding tensile, compressive and torsional loads or working under frictional wear conditions, also known as sintered structural parts.

Understanding the Benefits

Metal injection moulding (MIM) established itself as a competitive manufacturing process for small precision components which would be costly to produce by alternative methods. It is capable of producing in both large and small volumes complex shapes. The primary advantage of MIM is the production of intricate parts in stainless steel or other metals that cannot be die cast or cannot easily machined.

For engineers, if you want to do a good job of product structure design, you need to take the initiative to learn and understand the MIM process, perhaps you will find that you can achieve cost reduction by using the MIM process.
