用热塑性塑料和热固性塑料取代金属制造汽车车身外板的巨大潜在销路已引起人们的广泛重视。但是,现在看来在汽车发动机罩下的发动机室不大的空间可能存在同样大的塑料销售市场,只是这一市场不那么引人注意而已。塑料大量用于制造进气歧管、阀盖(气门套)、泵壳和其他装于汽车发动机室的刚性模塑件的应用正开始在北美和欧洲兴起。据美国咨询公司 Charles River 公司的统计和预测,汽车发动机室内用塑料的全球需求量,1992年为5.54万吨,到1995年将增至7.72万吨(销售额达5.70亿美元),年增长率高达20%。这一市场的迅速增长取决于成型加
The huge potential market for the manufacture of automotive body panels with metals such as thermoplastics and thermosets has drawn much attention. However, it appears that there may be an equally large plastic sales market in the small engine room under the hood of a car, but this market is less attractive. Plastics A large number of applications for manufacturing intake manifolds, bonnet (valve cover), pump housings and other rigid molded parts for use in the engine compartment of automobiles are beginning to emerge in North America and Europe. According to the statistics and forecasts of the consulting firm Charles River, the global demand for plastic for automobile engine room is 55,400 tons in 1992 and will increase to 77,200 tons (with sales of 570 million U.S. dollars) by 1995. The annual growth rate Up to 20%. The rapid growth of this market depends on the molding plus
