First, raw materials and related technologies backward. Poor quality fastener products is an important cause of poor quality raw materials and related technology behind making. Such as: cold heading steel wire rod is mainly used for manufacture of cold heading steel bolts, nuts, rivets, bolts and other fasteners, its chemical composition, microstructure higher, the current annual demand for cold heading steel is about 100 million tons, One auto industry requires 10 million tons, but due to technical reasons, is now cold heading steel wire made only 30 million tons, import nearly 700,000 tons per year. According to statistics from related departments, φ6.5mm following needs 150,000 tons, φ8mm be 160,000 tons, φ9mm, φ14mm the need for 80,000 tons, the domestic market in short supply.
Second, the low level of technology and technical equipment, can not guarantee the consistency of product quality problems. Mechanical parts are generally based on batch, mass production of products, but also more varieties of precision machining products, and therefore the production technology and equipment that require high investment and. Foreign multi-use high efficiency and precision of the plane, line or soft line for efficient automated production.
Third, the key manufacturing and test equipment Wen Ti, General Machine Parts right of each part of the Chicunjingdu Yizhi Xing, performance reliability and interchangeability requirements of Du is high, allowing Ji Zhi Chao Cha individual products, and after the factory before Inspection will be removed unqualified products, without high precision and high efficiency equipment, intense competition in the enterprise is difficult to survive and develop. Currently, China's auto parts for critical equipment is mainly dependent on imports of equipment due to wear and consumption of large equipment needs constantly updated and modified. The imported equipment and spare parts are expensive, if it is to accelerate the pace of development of the industry, must quickly address the problem of key equipment.
Fourth, new product development speed. China's machinery parts industry in technological innovation and new product development than the Guowai far behind especially SMEs Poor availability of technical and qualified personnel and lack of funds and the necessary instruments and equipment, but also the lack of relevant scientific information and technological exchanges and led to prolonged Genzong imitation stage, very few have their own intellectual property, product development, the current research on small, independent research and development enterprises in the power of few, this is the industry continue to develop the key issues
