上海詮豐精密工具有限公司系臺灣詮豐精密工具股份有限公司在滬獨資企業(yè)，坐落于上海的西大門風景優(yōu)美的嘉定區(qū)。成立于1997年7月，以生產銷售螺紋栓規(guī)、螺紋環(huán)規(guī)、螺紋切削工具等產品為主，以銷售螺紋專用設備為輔。為確保產品品質，從德國、日本引進先進的檢驗設備與校驗儀器，確保每一件產品出廠時符合合格證要求。    

CHUAN HONG PRECISION TOOL MFG.CO., LTD. was founded in July, 1983, specializing in manufacturing thread plug gauges, ring gauges, and thread cutting tool. In order to ensure the quality of products, we imported tool microscope, universal length measuring gauge 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. CHUAN HONG Calibration Laboratory is established since 2010 ,through TAF national quality assurance system in 2014.
