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 prototype to 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 debinding 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 mass production of complex-shaped precision metal parts and the manufacturing of composite materials through the bonding of different materials. We also implement insert MIM molding for parts with undercuts, contributing to the reduction of assembly, press-fitting, and other processes, as well as improving quality stability and reducing 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 → Utilizes micro injection molding machines and small molding machines. (＝Ensures stability in molding) → Generally 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 is necessary. (＝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.

Company information
Taiho Industry Co., Ltd. is a subsidiary of Japan Micro MIM Holdings Co., Ltd., and is responsible for the manufacturing of μ-MIM in collaboration with TAISEI KOGYO (THAILAND) CO., LTD. By using our self-developed feedstock (MIM raw material), we can mass-produce fine and high-precision metal parts that are difficult to manufacture with conventional MIM. We excel in areas that were previously challenging, suitable for parts with thin sections, products requiring high dimensional accuracy, and mass-produced items that demand high process capability indices, regardless of steel types or alloys. We have established a rapid and reliable evaluation system using the world's most advanced measurement and analysis equipment, directly linked to development speed. We cater to a wide range of industries, including not only medical devices but also optics, communications, and industrial equipment.
