When it comes to automobile joint ventures, we usually think of vehicle companies. But for parts and components , there is little concern. According to news recently, the National Development and Reform Commission and the Ministry of Commerce have issued the "Foreign Investment Industry Guidance Catalogue (Revised Draft for Solicitation of Comments)" to revise the foreign investment policy, and plans to invest the proportion of new energy automobile key spare parts projects for foreign investment in China. Control within 50%. This is the first time that China’s competent authorities have clearly defined the equity ratio of joint ventures for key components of new energy vehicles. In fact, since 2010, the discussion on the release of joint ventures has begun. The Chinese auto industry has been through reform and opening up for 30 years. Today, it is inevitable that this problem is encountered. However, for joint ventures of auto companies, new energy vehicles are The key point in the strategic planning of China's auto industry is that the relevant departments have naturally chosen the policy of controlling joint ventures and maintaining strategic initiative by controlling the equity ratio of joint venture companies. Since the reform and opening up, the opening of automobile joint ventures with multinational corporations is actually an important part of "market-for-technology". If there is no control over the joint venture's share ratio, multinational corporations will dominate the joint venture's right to operate. The joint venture's control of key parts and components gave China's newly-initiated new energy vehicles a technical lock and finally became a result of a multinational company's assembly base. In fact, in terms of core technology, the monopoly of foreign investment in the Chinese auto parts industry is very prominent. According to the 2009 China National Auto Parts Industry Survey and Research of the National Information Center, the top four domestic manufacturers of gasoline electronic control systems are UMC, Denso, Siemens vdo and Delphi Wanyuan, all with foreign investment backgrounds, including UMC’s market. The share of local companies is less than 1%. Some analysts believe that setting up a joint venture for key components and joint ventures not only sets a threshold for the establishment of new parts and components companies by multinational companies in China, but this limited variety also extends from the core components of new energy vehicles to traditional ones. The common parts of the car. However, any issue has two sides. In the case of a joint venture, the equity control of the Chinese party's equity is not less than 50%, which means that China will share and dominate the decision on profit distribution. However, if the comparison between Chinese and foreign forces is different, it may lead to different actual control areas and degrees in the actual game, and it is likely that the joint venture shares will become dominant over the Chinese side, but the technology remains controlled by the foreign parties. It is feared that the domestic enterprises will not use the joint venture to set joint ventures to limit the number of joint ventures, and independent brand enterprises must increase the research and development capabilities and control of key technologies. This is a topic that the industry has been appealing for many years. The policy given by the state is actually giving Chinese autos a boost in new energy vehicle technology. However, the policy is only binding on joint venture stocks. How to create productivity and R&D capabilities is a matter that companies need to consider.
Extrusion
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process.

Injection Moulding
Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called diecasting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that do not melt during the injection moulding of some lower-temperature thermoplastics, can be used for some simple injection moulds.
