Our operative concept has always been to serve our customers, raise our quality level, and be involved in R&D", since Chu Hua was established on Feb. 19th, 1974. Base on the above, we have maintain good relationships with our customers for many years. In the beginning, low carbon fasteners were our main products, and then we started to improve our forging technique and quality system, for the purpose of transfering product styles to involve regular and special parts, lowering manufacturing costs, and achieving volume production. We have acquired ISO 9002 quality assurance system from the ministry of economic affairs of Taiwan and A2LA assessment. Now, we are working for QS9000 and expect to practice next year.
