Plastic recycling machine has good development prospects

据了解，发达国家将汽车塑料的数量作为衡量汽车设计和制造水平的重要指标。每辆车使用的塑料量从1990年代的100-130公斤增加到2004年的152公斤和2006年的174公斤。现在的用量是230公斤。目前，德国使用的汽车最多，占车辆材料的15%以上。

然而，使用塑料并不意味着降低车辆的安全性。根据报告，在能量吸收部分，大多数主流车型仍然使用金属部件。塑料能量吸收部件也需要进行大量测试以收集数据并确认其可行性。

如今汽车中的塑料部件越来越多。专家预测，到2022年，汽车的平均塑料消耗量可能达到500公斤/单位或更多，占车辆材料总量的三分之一以上。

Today’s cars have already covered a large number of plastic parts, such as bumpers, wheel covers, license plates, dashboards, door panels, knobs, and even hoods and air intake systems, all using plastic parts.
“General plastics have a specific gravity of 0.9 to 1.6, and the proportion of glass fiber reinforced composites will not exceed 2.0, while A3 steel is 7.6, brass is 8.4, and aluminum is 2.7. This makes plastic the preferred material for automotive light-weighting. The use of plastics can reduce the weight of parts by about 40%, and the cost can be greatly reduced,” said Gao Wei, an engineer at the Materials Engineering Institute of Beiqi Futian Engineering Research Institute.

With the continuous innovation of materials, the concept of lightweight vehicles has become more and more intense under the current trend of energy-saving and emission reduction. In addition to the carbon fiber that can effectively reduce weight, cheaper plastics are beginning to slowly replace the precious metal parts. Some family cars are slowly gaining popularity. As a result, plastic waste can be generated in a very large number, so plastic recycling machines will become more and more popular.
