The Yiyang Rubber & Plastics Machinery Group Co held a seminar for 11 of its suppliers, on Dec 5, to discuss quality management so that it can improve its rubber machinery. This was a new way to improve the management of suppliers to build world-class rubber machinery. It complimented a seminar held in the first half of the year on product quality guarantees for suppliers. The company has also rated its suppliers and has sent quality management personnel to potential suppliers to scout for better quality suppliers and phase out those that do not meet standards.
