参考词条
补充资料:传递模塑
制造热固性塑料制品常用的塑料加工方法,也用于橡胶加工。热固性塑料或橡胶料(可以先行预热)在加料室内加热、熔融(图a),再在加压下进入加热的闭合型腔内(图b),经过固化后(或硫化),脱模即得制品。
传递模塑与模压相仿,都借助于压机,但又有注射成型的特点,模具设有浇口和流道。
这种方法要求热固性塑料,在未达到固化温度以前具有较大的流动性,而达到固化温度后又具有较快的固化速率,如酚醛树脂、三聚氰胺-甲醛树脂和环氧树脂等。用于橡胶制品加工时,胶料必须流动性好,硫化快。此法与模压相比,其优点是固化较均匀,生产周期短,尺寸精确度好,飞边修饰较易,嵌件和芯子不易变形,特别适于生产镶嵌件的制品。缺点是模具费用较大,模腔、浇口、流道中剩余料无法回收,故原材料单耗稍高。
