Today, the high technology has made great advances with the industrial development, and the devices become smaller, more complicated and high-powered, so that the uses and properties of Magnet wire are demanded various and advanced qualities. We have incorporated many high grade features such as heat resistance, chemical resistance, resistance to environmental degradation, low abrasion and outgas prevention to satisfy the needs of our customers.
Our motto is “To pursue quality, cost, functionality and workability based on the needs of our customers”. We have been working diligently on researching and developing the insulating varnish and copper wirings. Through our efforts, we have developed characteristic high quality products and our own original products such as solderable heat resistant wires, special self-bonding wires and self-lubricant wires.
Besides, our Magnet wire consist of very strict and special standard products in the field of quality standards. We acquired UL certification and also ISO-9001 certification.
We are ready to cope with the needs with considerable precision, for example, we adjust diamond dies to the standards in our factory for the quality control of Magnet wire.
Under the structure of manufacture and R&D as mentioned above, we keep very high share in the global market in the field of Magnet wire.
