We would like to share technical information about metal 3D printing developed by the Japan Micro MIM Group. The binder jetting method is becoming popular as a high-precision metal additive manufacturing (AM) technology. In the binder jetting process, a binder is sprayed onto metal powder from a nozzle to create the desired shape. During this spraying process, force is applied, which can cause distortion in the shape being created, especially for small metal parts. Additionally, when removing the workpiece, unnecessary metal powder may be blown away, and there is a risk that the workpiece itself could also be blown away. At Japan Micro MIM, we combine 3D printing and MIM technology to provide a seamless product development method from prototyping to mass production, referred to as "3.5D Printing." If you think "prototyping with MIM is expensive and time-consuming," or if you feel that "there are too many compromises with existing processing technologies" and are considering giving up on your design, please feel free to consult us about prototyping and mass production. *For more details, please refer to the PDF document or feel free to contact us.

The μ-MIM technology is optimal for the production of endoscopic surgical parts that require high precision in producing complex shapes from difficult-to-machine materials such as stainless steel. Other manufacturing methods find it challenging to process these materials, and even if they can be processed, it is very expensive and mass production is difficult. We manufacture fine, complex-shaped metal parts with high precision using molds in a net shape, ensuring consistency and stable mass production. Additionally, we can provide secondary processes such as plating, resin coating, and high-performance surface treatments. We also accept various types of plating, overmolding with PEEK materials, and various mirror finishes.

Through compounding, we shape and sinter materials of the same type or different types to provide high-value-added products with more complex shapes. Additionally, by combining different materials, it becomes possible to reflect their unique characteristics in the products. 【Features】 ■ We realize designs and complex-shaped products that cannot be achieved by other processing methods. ■ Sintered products with only the necessary features (such as strength, toughness, hardness, corrosion resistance, magnetic properties, weight reduction, complex shaping, insulation, conductivity, self-lubrication) are possible. ■ By shaping two types of materials (same material, different materials) during the molding process and achieving diffusion bonding through sintering, we ensure sufficient bonding strength at the interface. ■ In combinations of metals, structures such as dense layer-dense layer and dense layer-porous layer (porous layer) can be formed. ■ High freedom in material selection. However, please note that there are combinations that cannot be sintered, so please inquire in advance. For more details, please contact us or download and view the catalog.

The internal screw shape of the component is difficult to process through machining because cutting tools cannot enter the interior. In general MIM technology, the mold structure becomes complex, and the internal screw shape results in higher costs. At Tai Mori Industry, we can form the internal screw shape at a lower cost by using an acrylic sacrificial resin mold. Additionally, not only internal screws but also external screw shapes around the entire circumference, as shown in the photo above, can be achieved with first-class precision.

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.
