The groundbreaking ceremony for Michelin tire Shenyang plant was held on November 21, 2010 in Shenyang Economic and Technological Development Zone. With a total investment of 1.457 billion U.S. dollars, the project will produce 10 million tires for passenger cars and light trucks, 1.8 million for truck and bus tires, and 295,000 retreaded treads for trucks and buses.
“This project is a huge investment and is currently more than three times the amount of Michelin's total investment in the Chinese market. Prior to this, Michelin’s cumulative investment in China was US$450 million,†said Xiayi Fu, President of Michelin China Investment Co., Ltd.
According to Xiayifu, Michelin Shenyang Tire Co., Ltd. was established in 1995 and is the first joint venture company established by the Michelin Group in China. In 2003, it was transformed into a wholly foreign-owned enterprise.
It is understood that in recent years, with the rapid development of China’s auto market, consumers’ demand for tires for passenger cars and passenger cars has increased. Michelin has decided to establish a new factory in the Chemical Industry Park in Shenyang’s equipment manufacturing industry to produce high-performance products. Low rolling resistance green tires. Thanks to the special process, the weight of car and light truck tires produced at the new plant has been reduced, while the product still maintains the same load bearing and speed performance. Weight reduction saves both raw materials and reduces the rolling resistance of the tire, thereby reducing the vehicle's energy consumption. Every 10 million car tires can save about 27 million liters per year, reducing carbon dioxide emissions by about 68 million kilograms. More than 80% of truck and bus tires are high-tech tubeless tires.
According to Xiayifu, Shenyang's new plant project will implement the production line and equipment installation in the same period in 2014. At that time, 1,500 experts will be sent to Shenyang for installation and commissioning. At the same time, it carried out training for Chinese employees, dispatched 500 employees to study in Europe and North America, and trained 3,500 employees in China.
Extrustion Blow Molding Machine
Blow moulding machines can be divided into three categories: extrusion blow moulding machines, injection blow moulding machines and special structure blow moulding machines. Stretch blow molding machines can be classified into each of the above categories. Extrusion Blow Molding Machine is the combination of extruder, blow molding machine and die closing mechanism, which is composed of extruder and blank die head, blow expansion device, die closing mechanism, blank thickness control system and transmission mechanism. The blank die is one of the important components that determine the quality of blow molding products, usually including the side feed die and the center feed die. The storage cylinder type blank die head is often used for large products during blow molding. The minimum volume of the storage tank is 1kg and the maximum volume is 240kg. The parison thickness control device is used to control the parison wall thickness. The maximum control point is 128 points, generally 20~30 points. The extrusion blow molding machine can produce hollow products with a volume range of 2.5ml~104l.
Injection blow molding machine is the combination of Injection Molding Machine and blow molding mechanism, including plasticizing mechanism, hydraulic system, control electrical apparatus and other mechanical components. Common types include three-station injection blow molding machine and four-station injection blow molding machine. The three-station machine has three stations for preforming, blowing and demoulding, each of which is separated by 120 °. The four-station machine has more pre-forming stations, each of which is separated by 90 °. In addition, there is a dual-station injection blow molding machine with 180 ° between stations. The plastic containers produced by the injection blow molding machine are accurate in size and do not need secondary processing, but the mold cost is high.
The special structure blow molding machine is a blow molding machine that uses sheet, molten material and cold blank as parison to blow mold hollow body with special shape and purpose. Due to the different shapes and requirements of the products produced, the structure of the blow molding machine is also different.
