Over 50,000 unique parts Mass Production of Micro, High-precision and Difficult-to-form Products achieved by Micro-precision Processing

Our Strengths

Micro-precision Processing of Specialized Geometries with Precision Tool Manufacturing Technology

We specialize in "Micro-precision processing" using tool manufacturing technology developed over many years producing precision electronic parts. We can meet clients' needs for specialized processing of products with shaft diameters of 1mm or less, and have the capability to deep draw micro parts.

Clean Production Environment to Meet Quality Control Requirements​

Upon request, we can conduct cleaning, inspection, packaging and other processes prior to shipment in an on-site clean environment to prevent contamination (oil adhesion, inclusion of foreign material, etc.) and meet strict requirements of cleanliness.

Development of Original Manufacturing Methods Made Possible by In-house Production

Producing tooling and other equipment in-house is key to our technology and has allowed us to develop various original manufacturing methods. These methods enable us to mass-produce products and geometries impossible with commercially available tooling and equipment.

Design Simulation for Efficient Technical Proposals

We can collaborate with its clients from the early conceptual stages of a project. Using tool design simulation software aids us in responding flexibly to client design changes.
