For cap mould,usually we choose S136 as mold steel with hot runner system to keep good surface effect and save raw material. Before, We have made mold with 8 cavity,16 cavity, 32 cavity, 72 cavity, 128 cavity, etc.

There are two main ejection ways for cap mould, one is ejection by stripper, and the other is unscrewing,it depends on depth of thread. when the thread depth is greater than 1.2mm and thread continuous, will choose unscrewing ejection system, otherwise ejection by stripper. For unscrewing system, usually have two ways to reachthis action, one is by motor, the other is mechanical chain, by this way, itcan ensure thread not damage.
