Insert pin of vengting design for molded parts
Insert pin of venting:
It is difficult to make exhaust slot when end runner is not in parting surface during injection, and there is no matching gap available, but we could make the venting pin at end of runner side, and also the exhasut slot will be connected with the air in outside as the venting system, there are some tips for making the insert pin as following:
1. The venting pin should fixed with the mold by H7/g6;
