Q

Gel Particles/Fish Eyes

A

The essence of fish eyes is incompletely melted ultra-high molecular weight components or crosslinked gel in the resin. The solution approach is "raising temperature + filtration + changing material": increase the plasticization temperature to ensure full melting, use filter screens to filter out...

Q

Spinneret Clogging/Hole Clogging

A

The essence of spinneret clogging is that impurity particles or degraded gel in the melt clog the tiny spinneret hole inlets. The core of the solution is "cleanliness + filtration + regular cleaning": strengthen chip purity control to reduce impurity sources, use pre-filters (sintered metal filte...
