We have developed a manufacturing technology for metal powder injection molding applied to micro components, resulting in high-density, high-precision, and complex-shaped sintered products called "μ-MIM"!

At Taishō Industrial, we accept orders for the prototyping and mass production of high-density, high-precision, and complex-shaped "μ-MIM" products through metal powder injection molding. Metal Injection Molding (MIM) is a technology that involves mixing and kneading metal powder with a binder made of resin and wax, injecting it into a mold, and then sintering it after removing the binder to produce metal products. We are expanding these MIM technologies into micro components, developing our unique technology as "μ-MIM," and aiming for further technological advancements. "μ-MIM" offers high freedom in material selection, enabling the production of difficult-to-cut materials and high melting point materials. It allows for the mass production of complex-shaped precision metal parts and the manufacturing of composite materials through the joining of dissimilar materials. We also implement insert MIM molding for the production of complex-shaped parts with undercuts, contributing to the reduction of processes such as assembly and press-fitting, ensuring quality stability, and lowering costs, while accommodating screw shapes and transfers.

basic information

【Features of "μ-MIM"】 ○ High freedom in material composition allows for the molding of difficult-to-process materials and high melting point materials. ○ The use of fine powders results in a smooth surface. ○ Enables the production of composite materials through the bonding of dissimilar materials. 【Taiho Industry's MIN】 ○ Steel types → In addition to stainless steel, it accommodates a wide range of materials including mechanical structural steel, high hardness steel, heat-resistant steel, magnetic materials, titanium, and copper. ○ Binder → Short debinding time. → Minimal deformation during debinding. (= High precision) → Low residual carbon. (= High corrosion resistance) → Small binder amount. (= High precision) ○ Molding → Uses micro injection molding machines and small molding machines. (= Ensures stability in molding) → Basically adopts single-cavity molds. (= For high-quantity items, combines with a hot runner system) ○ Debinding and Sintering → Integrates the debinding and sintering processes. (= Significant reduction in process time) → No handling of debound products required. (= Stable quality) ○ Post-processing → Secondary processing, barrel polishing, plating, heat treatment, assembly, etc., can be handled in-house or by partner companies. ● For more details, please contact us or download the catalog.
