Corporate History

Guide to World Screw Threads

CHUAN HONG PRECISION TOOL MFG.CO, LTD. was founded in July, 1983, specializing in manufacturing thread plug gages, ring gages, and thread cutting tool. In order to ensure the quality of products, we imported tool microscope, universal length measuring gage and calibration instruments from Germany to examine our products. Each item leaving the factory was accompanied with a certificate of inspection, and thus CHUAN HONG could grow and develop in the industry.

To meet the need and demand of the user, a production line was added to manufacture screw taps in 1989. Furthermore, to strive for the best, we established the computer system in 1992 and reached the goal of computerized management. We have implemented ISO quality system since 1997 and were certified against the ISO 9001 standards in May, 1998. With the belief of "all staff are devoted themselves to promoting quality", we always make an effort to satisfy the customers by offering high quality products.
