日本マイクロMIMホールディングス List of Products and Services

We will provide technical information about "Metal 3D Printing," handled by the Japan Micro MIM Group. The binder jetting method is beginning to gain popularity as a high-precision metal additive manufacturing technology. In this method, a binder is sprayed onto metal powder from a nozzle to create the desired shape. During the spraying process, force is applied, which can cause distortion in the shape being formed, especially in the case of 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 be blown away as well. At Japan Micro MIM, we combine 3D printing and MIM technology to provide a seamless product development process 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 have given up on design because "there are too many compromises with existing processing technologies," please feel free to consult us about prototyping and mass production. *For more details, please refer to the PDF materials or feel free to contact us.

The μ-MIM technology is optimal for the production of endoscopic surgical parts made from difficult-to-machine materials like stainless steel, which require the high-precision manufacturing of complex shapes. Other methods find machining challenging, and even if machining is possible, it is often very expensive and difficult to mass-produce. We manufacture fine, complex-shaped metal parts with high precision using molds, 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 surface treatments.

The internal screw shape of the parts is difficult to process with machining because cutting tools cannot enter the interior. In general MIM technology, the mold structure becomes complicated, and the internal screw shape incurs high costs. At Taisou Industry, we can mold 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 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.
