The high price of modified plastics makes it easy to quantify the dilemma
The modified plastic plays a big role in the light weight of automobile, which can reduce the weight of the body and thus reduce the fuel consumption. But at the same time, the price of high quality modified plastics, let lightweight definitely add to the cost of many, native independent brands on sales and research and development of short board, more make modified plastics on the car application for car companies to its love-hate relationship.
Modified plastics play a big role in the light weight of automobile
Faced with increasingly stringent regulations on car fuel consumption, automakers are looking for ways to cut fuel consumption, including weight loss. By increasing the amount of modified plastic, it can reduce the weight of the body and achieve the purpose of reducing fuel consumption.
In Europe, the car with the amount of modified plastics has become a measure of vehicle design and manufacturing level of an important symbol, according to statistics, 1 kg of modified plastics can replace 2-3 kg denser material such as steel, but auto weight of a 10% drop in fuel consumption can be reduced by 6% - 8%. On the premise of ensure the vehicle overall performance, increase in the use of plastic materials, can effectively reduce the vehicle weight, reduce vehicle emissions and improve fuel economy, reduce automobile manufacturing cost at the same time. The largest amount of plastic in the world is Germany, which accounts for 15% of the total amount of plastic. By 2005 European standards had reached 13%. However, there is still a large gap between the use of cycling plastic in China and the developed countries.
The high prices of modified plastics are in a dilemma
In our country, brands begin to upgrade the application proportion of various light materials such as alloy, superstrength steel and engineering plastics in automobile products. Earlier this year, ford F150 announced to launch its first USES the lightweight body, vehicle weight 318 kilograms, recently announced its suvs explorers will become the first use this lighter volume production of quantitative design models, then edge, Lincoln MKX models will also take a related design. However, compared with foreign brands, domestic independent brands have encountered considerable challenges in light weight. Because foreign material suppliers have almost monopolized technology in some core parts, the purchase price of the independent brand remains high.
Some lightweight materials, while reducing weight, are obvious, but costly. For economical products, it is acceptable to lower the cost of the car to less than 20 yuan. At present, compared with local materials, the price of foreign materials is several thousand yuan per ton compared with local materials. The average cost per kilogram is several tens.
Local material suppliers of products are mainly applied to the bumper, fender, wheel cover and other components, the steering knuckle, chassis suspension is an core parts such as material supply, basic by bayer, basf, dupont and other foreign companies "monopoly". Such as bayer polyurethane composite materials, polycarbonate plastic can provide materials for Windows, new energy lithium battery, basf, long glass fiber material is mainly used for the engine mounting, the vehicle impact resistance components etc.
The policy is increasingly strict, and the weak links in the automotive industry chain, such as material supply and lightweight design, will still be severely tested. Independent brand enterprise sales and money compared with foreign capital is not dominant, currently represented by chery automobile parts enterprises have begun to parts supplier, an materials and the three of car companies from early research and development cooperation.
