Q

Selection Confusion Between LCP and High-Temperature Materials Such as PPS/PEEK

A

For high-temperature material selection, first define core requirements; LCP's irreplaceability lies in ultra-thin-wall flow; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Molds & Tooling material selection PPS PEEK PA9T

Q

LCP Hot Runner System Adaptation Problems

A

The success or failure of LCP hot runners lies in temperature control precision; both carbonization and stringing originate from temperature loss of control; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
