Q

PEI Shot Size and Machine Matching

A

PEI's 30~80% shot size window and 60% high-temperature lower limit are clear supplier guidance; machine matching is a prerequisite for degradation prevention and control; residence time needs quantitative calculation.

Q

PEI Flash

A

The clamping force calculation for PEI high-pressure processes cannot be omitted; 50MPa specific pressure is a clear standard; mold maintenance prevents gap widening.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

Poor PEI Melt Flowability

A

PEI's high viscosity requires dual guarantees of pressure and runner structure; 80~120MPa is the supplier's guidance range; high-flow grades are a material-level solution.
