“模具工业是美国工业的基石头”、“模具是促进社会昌盛殷实的动力”、“模具是金
模具是现代化工业出产的重要工业设备。在国民经济的各个工业出产部门都越来越多地
依托模具来进行出产加工。选用模具出产零、部件具有出产效率高、质量安稳，一致性好，
节约原材料和动力，出产所带来的本钱低一级长处，模具已成为今世工业出产的重要手法和工艺开展方
向之一。现代工业产品的种类开展和出产效益的进步，在很大程度上取决于模具的开展和技
术经济水平。现在，模具已成为衡量一个国家、一个区域、一家公司制作水平的重要标志之
道打针、热固性塑料打针、热固性冷流道打针、热固性注压、BMC打针、动力熔
需要由塑件规划、塑料打针机（运用）、打针模（运用）、打针工艺等一起确保。
个或多个有恒温的暖流道板及热唧嘴里，无冷料脱模，流道及浇口直接在产品上，
（4）热喷嘴选用标准化、系列化规划，配有各种可供挑选的喷嘴头，互换性好。
