We provide pressed parts specialized for difficult-to-machine materials (stainless steel) using stainless steel powder metallurgy.

Powder metallurgy specialized in stainless steel, which is a difficult-to-process material!

Our company offers high-quality stainless steel powder metallurgy parts utilizing the sintering technology of stainless steel developed over many years in MIM (Metal Injection Molding). Features include pouring fluid metal powder into molds and creating molded bodies through pressing. The molding time is extremely short, just a few seconds per unit, allowing for mass production. Additionally, with a relative density of 70-90%, the parts contain internal pores, enabling the production of lightweight components by controlling the sintering density. 【Features】 - Cost reduction through mass production of difficult-to-machine material parts and integration of components - Lightweight design possible due to internal pores in the products - Ability to provide products leveraging the extensive knowledge and technical expertise of the Mitsui Metals Group in metal materials *For more details, please download the PDF or contact us.

It is a technology suitable for mass production, achieving cost reduction! It is specialized in stainless steel, which is a difficult material to process.

"Powder metallurgy" is a method of manufacturing parts using metal powder as raw material, specifically referring to the pressing and molding process in a narrow sense. Flowable metal powder is poured into a mold, and a shaped body is produced through pressing. Since the forming time is very short, only a few seconds per piece, it allows for mass production. Additionally, powder metallurgy generally has a relative density of 70-90%, which means it contains pores internally. By controlling the sintering density, it is possible to create lightweight components. 【Features】 ■ Very short forming time of only a few seconds per piece ■ Capable of mass production ■ Provides high-quality stainless steel powder metallurgy parts ■ Capable of creating lightweight components by controlling sintering density *For more details, please refer to the PDF materials or feel free to contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
