How to deal with bubbles in the mold cavity in the production of polymer fiber materials

1. 1. Removing the protective film on the mold surface in the production of polymer fiber materials.

2. Secondly, put the mould for producing polymer fiber into the dryer.

3. Finally, after drying, the protective film of the mold in polymer fiber production can be pasted again to solve the problem of air bubbles in the cavity.
