Key Technology was founded in 1983 as the eastern base of the Katsushiro Group and specializes in the manufacture of parts and materials for construction and industrial equipment and heavy electric machinery. Over the early years, our primary area of business was sheet metal processing using gas cutting technologies. However, we have gradually expanded our business to accommodate the ever-changing requirements of our customer base to include fabricating longer materials, bending thick materials, welding, machining and sub-assembly.
Based on our own unique combined CAD/CAM system and production and sales management systems, we have established a fully integrated framework from the procurement of raw materials, cutting, secondary processing, plate working, right up to assembly of the finished product.
We make every possible effort to satisfy every need of our customers, by using a diverse range of equipment, from long presses (11m) and large 3000t presses, robot welding and large-scale machining facilities, suggesting optimum production methods using our own design and manufactured jigs and dies and harnessing our extensive experience in integrated production to suggest improvements to your design plans etc. Our base in China, TKM, also helps to accommodate the overseas procurement strategies of our customers operating in and around China.
