镶嵌注塑
为了满足装配和使用强度的需要,TPU制件内需嵌入金属嵌件。金属嵌件先放入模具内的预定位置,然后注射成一个整体的制品。有嵌件的TPU制品由于金属嵌件与TPU热性能和收缩率差别较大,导致嵌件与TPU粘接不牢。解决的办法是对金属嵌件进行预热处理,因为预热后嵌件减少了熔料的温度差,从而在注射过程中可使嵌件周围的熔料冷却较慢,收缩比较均匀,发生一定的热料补缩作用,防止嵌件周围产生过大的内应力。TPU镶嵌成型比较容易,嵌物形状不受限制,只要在嵌件脱脂后,将其在200~230℃加热处理1。5~2min,剥离强度可达6~9kg/25mm。欲获得更牢的粘接,可在嵌件上涂粘合剂,然后于120℃加热,再行注射。此外,应该注意所用的TPU不能含润滑剂。
