About東進工業
Leave it to us for various parts processing through machining!
In 1969, our company, Tohshin Industries, started primarily with lathe processing. Since then, we have consistently and sensitively captured the trends of the times, actively introducing NC lathes, machining centers, multi-tasking machines, and robots. Currently, we operate over 50 machines day and night, producing a variety of processed products such as powertrain-related components for agricultural machinery and components related to industrial robots for major manufacturers. To overcome the challenging times ahead, our company will remain committed to the fundamentals of quality focus, cost reduction, and adherence to delivery schedules, engaging in management that is faithful to these principles. Furthermore, achieving these goals requires talented personnel. We will cultivate our workforce so that each employee develops an interest in processing technology, hones their skills and knowledge, engages independently in new processing endeavors, and aspires to be a skilled group that continuously progresses with a positive outlook. To continue living and developing alongside the times, we will strive for even higher quality and goals, and we kindly ask for your continued support.
