What’s usually your biggest headache on multi-cavity packaging molds?

For those working with 16+ cavity packaging molds, what usually causes the most trouble for you?

For me it’s usually one of these:

•cavity-to-cavity filling variation

•venting consistency

•gate vestige control

•cooling balance over long production runs

Interested to hear what others run into most often.

We’re working on a PC shaft part and facing an issue with the gate vestige. The customer requires the gate protrusion to be below 0.02 mm, but we cannot change the hot runner gate diameter.

We’ve tried adjusting processing parameters, but it’s still difficult to meet this requirement consistently. Has anyone dealt with a similar situation? Any suggestions on improving gate appearance without modifying the gate size?

I have a question about sink marks on this product. We’ve already tried adjusting the injection molding machine parameters, but the issue still isn’t resolved.

The customer cannot accept these sink marks. Does anyone have suggestions on how to fix this?
