Raw materials and related technology behind the low level of technology and process equipment, which restricts the development of poor quality steel fasteners basic parts, chains, springs, bearings, molds and other products used, less variety of specifications, a direct impact on the basic items of quality, hydraulic parts and hydraulic parts casting and the quality of products related to electronic control technology is backward, but also directly affect the quality and reliability of hydraulic parts. Mechanical parts are generally based batch, mass production, and there are many varieties, high precision machining products, and therefore the production process and equipment requirements, large investments. Foreign multi-use efficiency and precision of the plane, production line or flexible lines, to achieve efficient automated production. But some of our basic parts business by financial constraints, little investment, corporate self-transformation ability, advanced equipment not supporting the less impact on the quality of products on the grade. Comprehensive analysis of the main cause of these problems is that: 1. Enterprise foundation is weak due to poor foundation of Machine Components Industry, weak economic foundation, less investments in technology, development is weak, unable to meet the industry to introduce a host, you need to joint ventures, cooperation, rapid development , resulting in mechanical foundation of the domestic market share declined. Lack of strong policy support for Machine Components Industry 2. Although the State in the national industrial policy, a clear focus on supporting important mechanical basic parts, but the lack of appropriate supporting policies, such as mold industry tax burden too heavy to enjoy value-added Part corporate tax return, the country is less than one hundred, too narrow, limited role, but also the need for policy to continue to support. Therefore, in order to improve the market competitiveness of our basic pieces of machinery products to better meet China's machinery industry on the basis of pieces of supporting domestic demand, basic parts industry in China is expected to face further adjustments to integrate the advantages of resources, elimination of backward enterprises and imported products. In the next five to 10 years, the industry will be in the development of brand products and famous enterprises, technical innovation, improve competitiveness and strengthen the domestic market and other intensive management and strive to attain greater progress and breakthroughs.
