Water-assisted injection molding: Water-assisted injection molding technology is an advanced injection molding process in which part of the melt is injected into the mold cavity and high-pressure water is injected into the melt through the equipment to finally shape the workpiece.
Due to the incompressibility of water, the water front creates a solid interface, squeezing the inner wall of the product into a cavity, and the water front also acts as a rapid cooling. Therefore, the water supplement has many advantages over the gas supplement. Research and application show that the water supplement can produce thinner and more uniform cavity wall, and the inner surface of the flow channel is very smooth. Especially for thick wall workpiece, the cooling time can be greatly reduced compared with gas auxiliary.
High gloss injection molding: Highlights the basic process of injection molding is prior to injection molding, through the use of high temperature and high pressure steam will mould surface rapidly warming, the forming die cavity surface temperature of resin plastic glass transition temperature (Tg) above, then the plasticizing good plastic melt into the closed mold cavity, the injection stage, mold temperature by high temperature and high pressure steam remains the same, When the injection is finished, the air supply is stopped, and the water vapor in the pipe is blown clean by air pressure of the air pipe. After that, the cooling water is injected to make the mold temperature drop rapidly until the mold is cooled and the product is removed by opening the mold

Foreign investment is just around the corner. According to statistics from the China Association of Automobile Manufacturers, in 2009, about 110,000 engines were remanufactured, about 60,000 more transmissions were manufactured, and about one million generators and starters were manufactured. The output value was less than 2.5 billion yuan. A few years ago, the annual output value of American auto parts remanufacturing has reached 50 billion U.S. dollars.
However, the potential for remanufacturing of auto parts in China still attracts foreign companies to compete for investment. According to statistics, as of the end of last year, China’s civil vehicle ownership was close to 80 million vehicles, and nearly 4 million vehicles were scrapped domestically.
Jinan Fuqiang Power Co., Ltd., which operates well in the current 14 remanufacturing fields, is a Sino-British joint venture specializing in engine remanufacturing. The foreign party is the Liszt Group in the United Kingdom, and its holding company, Sandwell Company in the United Kingdom, is the largest in the UK. Specialized engine remanufacturing company.
On August 27, as the first powertrain remanufacturing base in China and the first batch of pilot enterprises for auto parts remanufacturing, the Volkswagen FAW engine (Dalian) was established as a powertrain remanufacturing base jointly invested by Volkswagen Group and China FAW Group. ) The company's powertrain remanufacturing project will be put into production in Dalian, with an initial investment of approximately RMB 100 million. It will begin with engine remanufacturing and will include transmission remanufacturing in the future. The project will initially have an annual production capacity of 5,000 units.
Also in August, Tianqi (002009.SZ) announced that it has signed a framework agreement with ALBA of Germany. The two parties intend to spend 100 million yuan to enter the recycling market of China's end-of-life vehicle, thereby extending the business to the demolition of used cars Sorting equipment field. According to the data quoted in the Tianchi’s private placement plan, in 2009, more than 2 million vehicles were recycled and dismantled in China. It is estimated that after 2020, the number of vehicles to be recycled will be about 10 million.
Chery, the largest remanufacturer in the field of chassis drive systems for commercial vehicles in North America, also expressed a keen interest in the Chinese auto remanufacturing industry and prepared to take the opportunity to enter the Chinese market.
尴尬 Situation “Our remanufactured parts and components have a market but no old machine, and we can only manufacture 200 engines in a year. Our old machine comes from Shanghai Volkswagen, Shanghai GM and other after-sales networks that have strategic cooperation with us, or It is a defective product produced by its 4S shop or the main engine plant. Many scrap cars have gone directly to the steel mills.†An automotive remanufacturing company CEO told the “First Financial (microblogging) Daily†reporter.
According to the “China Automotive Market Yearbook 2010†statistics, in 2009 China’s vehicle ownership was 7741.65 million units, and the actual scrapped amount accounted for only 2.61% of the inventory, which was far below the level of 6% to 10% of write-off rates of write-offs in developed countries such as Europe and America. .
In July last year, the publication of the Regulations on the Administration of Recycling and Dismantling of Endangered Motor Vehicles (Draft for Soliciting Opinions) (hereinafter referred to as the “Draft for Commentâ€) brought a dawn to auto dismantling companies and remanufacturers. The automobile assembly and other parts and components proposed in the “Draft for Soliciting Opinions†can be sold to remanufacturers, continue to be used after remanufacturing and processing, and encourage automobile dismantling companies to form long-term strategic cooperation with automobile manufacturers and remanufacturing enterprises. alliance.
According to sources, the Regulations on the Management of Recycling and Dismantling of Scrapped Motor Vehicles will be introduced before the end of this year. However, due to the coordination problems between government departments, the remanufacturing of auto parts will still be in a dilemma of “not cheating on riceâ€.
The conditions for the development of China's automobile remanufacturing industry have matured, but the source of scrapped vehicles has not yet been completely resolved, and remanufacturing companies still face the embarrassment of “a miracle is difficult for women to be without riceâ€. With the support of policies, the automobile remanufacturing industry will enter a new stage, and foreign-funded enterprises are also observing this huge potential market. In 2008, the National Development and Reform Commission first launched the "Administrative Measures for the Remanufacturing of Auto Parts", and identified 14 auto companies as remanufacturing pilot enterprises. On September 14, three years later, the National Development and Reform Commission issued a "Notice on Deepening Remanufacturing Pilot Work" again, which will expand the scope of remanufactured product types and pilots, and increase support.
