Powder injection molding(PIM) was first used in the 1920s, and a few current applications trace
Their origins back to the 1960s. However, up to the 1990s, PIM lacked the required infrastructure for broad success. Accelerated growth in the number and size of applications in recent times has generated much attention on the technology.

First demonstrations of the PIM technology were performed when plastic injection molding was a new technology. An early product was the ceramic portion of the automobile spark plug.
Demonstrations with cemented carbides(compositions based on WC-Co) date to the 1960s, and metal powder injection molding has been in constant use since the 1970s. Over the years, many products and technologies have been developed, but widespread commercial success did not take place until the 1990s when standardized processes emerged.

Today, the technology has gained much credibility. Powder injection molding is one of several net-shape production routes, with applicability to most engineering materials.
Initially the common features of various proprietary PIM technology were not understood; thus, in early years there were different names assigned based on the materials - CIM for ceramic powder injection molding, CCIM for cemented carbide powder injection molding(also referred to as HMIM for hard material or hard metal powder injection molding), and MIM for metal powder injection molding . Overall the processes are very similar, with the powder chemistry and sintering temperatures being the key difference.

Powder injection molding is most competitive when used to form complicated and durable components, especially when the components require high properties. Further, PIM is economically best suited for mass production. Recognition of the wide range of applications, materials, component features, and properties are now helping to identify new uses that are contributing to a period of sustained expansion.

PIM(Powder Injection Molding) is an established manufacturing technology for producing small,
complex, tight-tolerance, high-performance, net-shape parts with metal, ceramic or carbide powders.
PIM is a cost effective alternative to machining or investment casting parts, especially to complicated parts that are usually produced through several steps of precise processes after molding. It offers tremendous single step parts consolidation potential and design flexibility as well as enhances preciseness and density of the PIM-applied products.
