About Us
Founded in 1993 by our president, Chen Yi-chang, we have 10 years of experience in making auto/motorcycle valve stem seals. Originally named Hung Pin Hsing Rubber Enterprise Co., Ltd., we were engaged in making a wide variety of auto/motorcycle oil seals and rubber parts in our initial stage. After continual efforts made to improve and modify our products, we have boosted our sales revenue and expanded our factory. Now, utilizing automated production lines instead of the former labor-intensive production methods, we are capable of turning out superior products and were granted ISO-9001 certification by UKAS in 2002. With our products having established a solid reputation in both the domestic and overseas markets, we have recently formally renamed ourselves Ming Chang Rubber Industrial Co., Ltd. Promoting our products worldwide under the WOK, CHK, SOK, OKS, UMI and SUN brands, we are also an OEM supplier of valve stem seals for makers of cars, motorcycles, buses, trucks, and trailers. In addition, to maintain the quality of our products, we have purchased a complete range of specialized production equipment, expecting to provide our customers both at home and abroad with the best possible product quality, the most competitive prices, and the shortest lead time customers can get in the industry. Our main products encompass oil seals for European car models and valve stem seals for U.S. and Japanese car models as well as for motorycles and diverse kinds of engines. We can also develop new products according to customers samples. To ensure total customer satisfaction, we will continue to devote ourselves to innovation, R&D, and after-sales service. With top-flight expertise and technology, we wish to become an appointed OEM supplier of all renowned players in the field around the world in the near future.
