Professionals in the processing of hardened materials such as SKD11! We handle cutting, electrical discharge machining, and grinding in-house, and provide services from heat treatment to surface treatment.
We are a company engaged in the design and manufacturing of precision press molds, as well as machining centers, wire cutting, and grinding processes. In parts processing, we use wire cutting machines, machining centers, shape electric discharge machines, form grinding machines, and small hole electric discharge machines to manufacture mold components and industrial machine parts. (We specialize in processing hardened SKD11 material and can also perform electric discharge tapping.) We can handle precision parts processing from just one piece! We have over 2000 successful manufacturing records! This time, we present a collection of examples of precision parts processing selected from our numerous achievements. ▼▼▼ For more details, please download the PDF below ▼▼▼ 【Processing Examples - Excerpts from the catalog, detailed photos are included in the catalog】 <Wire Cutting Processing> ■ Mold Parts Material: SKD11 HRC60 Hole processing with wire <Grinding Processing> ■ Mold Parts Material: SKD11 (HRC60) A challenging process to eliminate the step at the junction of R and taper. *For more details, please refer to the PDF document or feel free to contact us.

Applications/Examples of results
The main applications are press molds, press mold components, and industrial machine parts. Recently, there has been an increase in the use of hardened material components such as SKD11 for wear-resistant parts like sliding surfaces. There are successful cases where parts that were traditionally made from materials like SS400 or S50C and treated with hard chrome plating have been changed to hardened SKD11 material, and further plated, resulting in product lifespans that exceed those of conventional methods.
