Specialized in mass production of automotive parts. Leave precision machining of iron castings, forgings, and aluminum to us.
Quick, safe, stable. A reliable partner.
Since its establishment in 1953, we have a proven track record of processing automotive mass production parts. We have experience handling production volumes ranging from 1,000 to 150,000 units per month.
High precision assurance of electric components requires environmental stability. Temperature changes are controlled in a temperature-controlled room to achieve stable production.
No more rejections for processing! We are offering a collection of 6 successful case studies that solve the challenges of prototyping, difficult processing, and short delivery times.
It protects iron-based materials, parts, and products from rust just by wrapping them. It can be applied in the processes of molds, equipment, materials, parts during processing, storage, and shipping (export).
High precision × mass production made possible by consistent manufacturing! Adding further value to precision machining technology.
Achieve cost reduction for PCD and CBN inserts used for cylinder head, block machining, such as for chamfering, grooving, and internal diameter boring!
Achieves over 8 times the lifespan compared to carbide reamers! This is a PCD reamer for machining automotive engine valve guide holes!
Achieving high precision and long lifespan for steering ball joint processing! It combines high precision with low cost!
Achieved a 30% cost reduction with the same lifespan and quality as Japanese-made CBN tools! Currently adopted by major brake parts manufacturers and truck manufacturers.
Quality control for the high airtightness required in electric components is conducted through strict measurements using a helium leak tester to ensure stable quality management.
