Metal Injection Molding in Germeny (Gmbh) | MIM Process

What is Metal Injection Molding?

Metal Injection Molding (MIM) is a cutting-edge technology designed for manufacturing intricate, high-precision components in a cost-efficient way, making it particularly suited for mass production. The process involves mixing metal powders with a binder system to create feedstock, which is then molded and sintered into solid parts.

MIM accommodates a wide range of materials, and the high density achieved during sintering imparts excellent performance characteristics. Thanks to its ability to produce complex shapes at competitive costs with superior properties, MIM components are extensively used in industries such as automotive, general manufacturing, tooling, medical, dental, aerospace, IT/mobile devices, and luxury goods.

This technology, also referred to as powder injection molding (PIM) or metal powder injection molding, is applicable for the large-scale production of parts made from metals (MIM) or ceramics (ceramic injection molding).

Metal injection molding in Germany – MIM parts in Germany (Gmbh)

A key advantage of metal injection molding (MIM) is its ability to manufacture intricate components in a single process, delivering high-strength, precision metal parts. MIM components feature precise dimensions and shapes, allowing the seamless integration of undercuts, drill holes, cross holes, threads, lamellas, and even relief-like details such as logos and item numbers.

The MIM process offers a cost-efficient way to produce highly durable parts with consistent quality, making it ideal for diverse applications where precision and performance are essential.

At Meta Build Industries, we specialize in the MIM process for small, technically demanding components requiring strict precision. We proudly supply metal injection molding (MIM) parts across Germany.

Molding

Injection molding operates similarly to plastic injection molding and utilizes the same machinery. In this process, pelletized feedstock (materials used in metal injection molding) is fed into an injection molding machine, where it is heated and injected under high pressure into a mold cavity.

This produces a „green part,“ which cools and is ejected from the mold, allowing the cycle to repeat. Since only the binder components are melted to transport the metal powders, the process occurs at approximately 200°C.

Molds can feature multiple cavities to enhance production efficiency. To account for the shrinkage that takes place during sintering, the mold cavity is designed to be about 20% larger. The shrinkage rate is meticulously calculated for each material used in the process.

Debinding

Following the injection molding stage, the formed part undergoes the de-binding process, which involves removing the binder materials from the molded Metal Injection Molding (MIM) component.

Typically conducted in multiple stages, this process removes most of the binder while leaving enough to maintain the part’s structural integrity for safe handling during transfer to the sintering furnace.

Binder removal is achieved through various methods, with solvent extraction being one of the most commonly used techniques. After de-binding, the part becomes semi-porous, allowing any residual binder to evaporate during the sintering phase.

Sintering

The parts are placed on ceramic setters and loaded into a sintering furnace designed to achieve high temperatures and maintain a controlled atmosphere. Within the furnace, the „brown“ parts are gradually heated in a protective environment to remove any residual binders.

As the binders vaporize, the temperature is raised further, causing the metal particles to fuse together as the voids between them close. This process results in the parts uniformly shrinking to their final dimensions, creating a dense, solid structure.

The density of sintered parts typically exceeds 97% of their theoretical density for most materials, providing the finished product with properties comparable to those of wrought metals.
