Company Overview

Our company operates under the brand name ""SOUL"", and began operations in 1926. We are a pioneer of scroll chuck manufacturing in Japan.
In 1969 we led the industry in beginning development of mass production-use design chucks. Our company has the largest variety of car part-use design chucks in Japan, and enjoys the No. 1 domestic share in this area. Our company also has international cooperation in after-service from companies including ITW-Workholding (USA) and Forkaldt (EU). Our company continually challenges itself to be the manufacturing leader of every age.

A design chuck is an order-made work holding tool designed and manufactured to have an optimum structure for a given work configuration, level of process precision, set of work conditions, or machine being utilized. The design chucks made by our company are utilized in a wide array of domestic and international automobile part processing lines. Our company proactively handles difficult and high-risk requests, and in the rare circumstances when a problem arises, we always give the highest priority to its resolution.
In the area of automobile parts our company has performed over 100,000 varied layouts, and is skilled at oscillating, claw lead-in, claw rotating, finger, collet, diaphragm and other structures, as well as combination designs of these. We carefully design and select the steel grades for each individual processed part, and deliver these products fast. Our company is fully capable in all stages of the manufacturing process including high-precision processing, heat treating, finishing, assembly, inspection, shipping and delivery.
Domestically, we receive requests for our design chucks both directly and from set makers, and we sell our products to automobile makers and automobile part makers. Internationally we perform sales to machinery makers through our local cooperating partner, the machine and tool trading company ITW Workholding Group. Additionally we sell our products to companies engaged in construction machinery, bearing, and air conditioning manufacturing. Our company has the top domestic share of design chuck deliveries and sales.
