To achieve the sustainable environment, a universal goal for all human beings, we operate our business to reduce and eliminate environmentally hazardous substances and to reduce waste and energy consumption.



In our effort to meet our customer’s expectations, we design and develop our own technologies to manufacture straight wires and long coiled sheaths. If a client requests us to develop a new product, we will work partner together by researching its processing methods and developing the process required for mass-production.
