Intensification of penetration in the next two to three years
Recently, with the formal opening of Shanghai Baixie Pai Auto Service Co., Ltd., “Aust-Agnes Bacchuszhuang Storeâ€, Japan’s largest automotive supplies chain Au De Bacques took the first step to enter China. It is reported that a number of foreign-funded automotive service companies have plans to open stores in China and will compete fiercely in the Chinese market in the next two to three years.
Au De Bacchus blooms all over China in five years
It is understood that Shanghai Baixie Pai Auto Service Co., Ltd. is a joint venture established by Japan's Aode Bacchus Group, Shanghai Pai Auto Technical Service Co., Ltd., and Japan's KOSHIDA Co., Ltd., with a total investment of 35 million yuan, and the proportion of the three parties is 65 respectively. %, 20% and 15%.
Xu Hao, general manager of Shanghai Pai’s Automotive Technical Services Co., Ltd., one of the joint venture partners, stated that the Au De Bacs chain will meet the needs of all owners as much as possible, from providing automotive perfumes to large-scale car conversions, from Santana to Mercedes-Benz. BMW and other high-end cars.
It is reported that Au De Bacchus is Japan's first comprehensive automotive supplies store with a one-stop service, and has more than 500 chain stores worldwide. The chairman of the company, Sumano Ichino, announced a plan to “grasp the cities†in China: The joint venture company plans to enter the Beijing market next year and will open 100 chain stores in China within five years.
Intensification of Foreign Investment in Automotive Service Trade
Even as Au De Bacchus took root in China, its direct competitor in Japan, Huang Hat Co., Ltd. also decided to open its first Chinese store in Shanghai International Automobile City under construction. 165,000 square meters.
It is not just Japanese companies that have the same considerations. The world's largest car repair chain company, American AC Deco, has also disclosed that in the next two to three years, it will develop more than 200 car repair chain stores in China.
Zhang Yuxian, deputy director of the Development Research Department of the National Information Center, believes that after China's accession to the WTO, China will promise to gradually open up services to foreign investors. In order to seek more initiatives in the Chinese auto market, foreign investment has penetrated both in the past from purely manufacturing participation to procurement and sales services.
It is understood that a mature international automotive market, after-sales service accounted for more than 50% of the profits of the entire industry chain, the current national after-sales market capacity of more than 800 billion yuan. From the current point of view, the automotive service market is the only area that has not been fully opened to foreign investors. Therefore, the giants of the international auto service market are also stepping up their landings in China and are only waiting to be flexed when the market is released next year.
Product classification
1. Pu pneumatic pipe
2. Pu (polyether) pneumatic pipe
3. Pu (polyurethane) bobbin
4. Pu (polyether) bobbin
difference:
Polyurethane pneumatic pipe is over air type. If it is used for over water, its service life will be affected,
Polyether pneumatic pipe can pass air or water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic pipe.
The bobbin is wrapped with a layer of fiber in the middle of the common pneumatic pipe. Therefore, the bobbin is more solid, pressure resistant and non explosive than the common pneumatic pipe.
Product selection
What should be considered when choosing the type of plastics for blow molding pneumatic pipe?
The following aspects should be considered in the selection of pneumatic pipe materials.
Whether the wall thickness of the welded blank of the pneumatic pipe can be kept uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic pipe is bright, whether the demoulding is easy, and whether the strength can meet the requirements, etc.
Performance comparison of plastics for blow molding pneumatic pipe. The pneumatic tube formed by blow molding is in thermoelastic state, and its density is smaller than that after cooling and shaping, resulting in shrinkage. For the general size of pneumatic pipe is not strict, forming shrinkage has little effect. But for the pneumatic pipes of specified size, such as some hoses used in precision machines, large shrinkage has a considerable impact. The larger the blowing volume is, the more significant the effect is.
The advantages of extruding and blowing plastic forming pneumatic pipe are less investment in production equipment, simple equipment structure, easy mold manufacturing, high forming of pneumatic pipe during production, uniform temperature control, and various specifications of pneumatic pipe can be formed. The disadvantage is that the wall thickness uniformity of pneumatic pipe is poor.
The advantages of injection blow molding pneumatic pipe are that the plastic pneumatic pipe has good product quality, accurate dimensions, no seams, uniform wall thickness, multi-mode molding production, high degree of automation, which is very suitable for large-scale high-efficiency production of small specifications. The disadvantage is that the investment of equipment and molding die is large, and the operation and production need skilled workers.

Tips for pneumatic pipe
Polyurethane pneumatic hose is suitable for compressed air, ordinary industrial water and non corrosive oil. In order to maintain a long service life, it must be used under rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly. If it exceeds the limit, the hose may break. If the fluid temperature is too high or the fluid is corrosive, the hose may break. If the working environment temperature is too high or there is chemical gas in the working space, the hose may crack. If the hose is stored in a wet place or the storage period is too long, the hose may hydrolyze or age, which may lead to fracture
