In recent successes, Shanghai Automotive announced on October 12 that its total vehicle sales in September exceeded 260,000 units, an increase of 90.7% year-on-year, followed by a new historical high for single-month sales after August; its third-quarter sales reached 720,000 units, The growth rate was 92%, a 5.8% increase from the previous month, and the growth momentum was strong. From January to September, the sales volume of Shanghai auto vehicles has exceeded 1.94 million, an increase of 47% year-on-year, exceeding the annual sales in 2008.
In terms of passenger cars, September sales increased by 90% year-on-year. Among them, Shanghai Volkswas sold more than 70,000 units, an increase of 83% over the same period last year. Newly-listed new-leaders monthly sales exceeded 8,000 units, August’s mid-to-high-end model Haoyue monthly sales also exceeded 2000 units; Shanghai GM sold over 71,000 units. , a year-on-year increase of 99%. Recently, the newly-listed mid-to-high-end models, Xinjunwei and Xinjun, both sold more than 7,000 units in sales. The self-owned brands, Roewe and MG, sold more than 9,000 units, a year-on-year increase of 109%.
For commercial vehicles, September sales increased by 91% year-on-year. Among them, SAIC-GM-Wuling sold more than 95,000 micro commercial vehicles, a year-on-year increase of 97%. It firmly took the top position in domestic micro-vehicle sales; Nanjing Iveco IVECO and Yuejin sold more than 80,800 vehicles, an increase of 72% year-on-year.
Since the beginning of this year, while achieving excellent sales performance, Shanghai Automotive has further consolidated its competitive advantage in the domestic market: the market share has steadily increased, and Shanghai Automotive’s domestic market share reached 20.2% in January-August, which is higher than the same period of last year. 1.9 percentage points in the fierce competition in the market to expand the leading edge; sales of mid-to-high-end models rose sharply, with the recent new Regal, New Jersey, the new LaCrosse, Hao Rui and many other popular new products introduced by the market, the company The sales volume of mid-to-premium models has increased from 24,000 units in January to 39,800 units in August, showing continuous growth momentum and significantly improved profitability. Independent brands have gradually gained market recognition. In 2009, Roewe brand won the JDPower after-sales service satisfaction CSI. The fourth survey and sales satisfaction SSI survey ranked first, a wide range of positive word of mouth formed among consumers strongly promoted the sales of products. In the market with a displacement of 1.8L or above, Roewe brand sales ranked the forefront.
Die-casting is a metal casting process characterized by the use of the inner cavity of the mold to apply high pressure to the molten metal. Moulds are usually made of stronger alloys, and this process is similar to injection molding. Most die-casting castings are non-ferrous, such as zinc, copper, aluminum, magnesium, lead, tin and tin and their alloys. According to die casting type, the cold chamber die casting machine or hot chamber die casting machine is required.
Foundry equipment and moulds are expensive to build, so the casting process is generally used to produce large quantities of products. It is relatively easy to make die-casting parts, which generally require only four major steps, and the incremental cost is very low. Die-casting is especially suitable for making large quantities of small and medium sized castings, so die-casting is the most widely used in various casting processes. Compared with other casting techniques, the die-casting surface is more flat and has higher dimensional consistency.
Several modified techniques are introduced on the basis of traditional die-casting process, including the non-hole die casting process which reduces the air hole of casting defects. It is mainly used to process zinc, which can reduce the waste material and increase the yield of the direct injection process. There is also a new die casting technology developed by general dynamics company and semi-solid die casting.
A method for improving the structure and mechanical properties of high polymer chains in high polymer chains is arranged by stretching. Stretching can be divided into uniaxial stretching and biaxial stretching, while the former allows the chain to be aligned in one direction, while the latter arranges the chain along the plane.
Forging is a kind of pressure of forging machinery for metal blank, make its produce plastic deformation in order to obtain certain mechanical properties, a certain shape and size of forging processing method, forging, forging and stamping) of one of the two part. By forging can eliminate the metal smelting process of as-cast loose defects, such as optimizing the microstructure, at the same time because of the intact metal flow, forging generally better than that of the same material on the mechanical properties of the castings. The important parts with high load and severe working conditions in the related machinery, except for the simple and usable rolled plates, profiles or welding parts, are used for forging.
