联邦德国的专家认为,应用传统的金属材料制造汽车零件实现轻量化的潜力已近挖尽,而采用改性的耐高温工程塑料则是实现轻量化的新途径。当然应用这种比钢和铝轻的贵重塑料制造发动机的受力零件时,必须对功能和质量、原料来源和价格及选取材料和工艺方法的数理逻辑进行分析,肯定其切实可行性。可熔型芯技术的应用将推动进气管和水泵等承受高温高负荷且要求具有良好流体力学性能的发动机零件实现塑料化的研究进程。 Experts from the Federal Republic of Germany believe that the potential to reduce the weight of automotive parts using traditional metal materials is almost exhausted, while the use of modified high temperature engineering plastics is a new way to reduce weight. Of course, the use of such light steel and aluminum than the light of the manufacture of engine parts force, the function and quality must be analyzed, the source and price of raw materials and mathematical logic of selected materials and processes must be analyzed to confirm its practicability. The application of fusible core technology will promote the progress of plasticization of engine parts such as intake pipe and water pump that are subject to high temperature and high load and require good hydrodynamic performance.
