Injection from cap mold’s core part!
Post: 2022-07-25
On regular condition, for hot
runner cap injection mold, the injection is always from mold’s cavity part.
Then, you will find the injection point on the cap’s top outer surface. In some
case, for good appearance purpose, you don’t want there is injection point out
of cap surface, but you still need hot runner mold. Then, how to do? The
solution is to arrange the injection direction from mold’s core part. It\'s not
just about turning the mold upside down. Hot runner design, mold’s cooling
tunnel design and cap ejection structure are all different totally. In fact, if
you want to do in-mold-lable on the cap’s top surface, injection from core is
also a necessary precondition. On Kronce, we have matual solution to help you!
