根据美国Freedonia集团的最新报导,今后4年中注模塑料的需求量预计将大幅度增长。需求量的增长反映了注模工艺的广泛适用性以及树脂和加工方法所取得的进展,同时也反映了塑料在设计、成本和性能等方面相对于木材、金属及其它材料所占有的优势。热塑性树脂由于在加工、设计及回收等方面优于热固性塑料,因此将占据主导地位。注模聚丙烯的发展前景最被看好,不过工程塑料(包括聚碳酸酯以及尼龙
According to the latest report from the United States Freedonia Group, the demand for injection molded plastics in the next four years is expected to increase significantly. The increase in demand reflects the wide applicability of the injection molding process and the progress made in resins and processing methods. It also reflects the superiority of plastics in terms of design, cost, and performance relative to wood, metal, and other materials. Thermoplastic resins will dominate because they are superior to thermosets in processing, design, and recycling. The prospects for the development of injection-molded polypropylene are the most promising, but engineering plastics (including polycarbonate and nylon
