Solvay demonstrates use of overflow tabs to improve weld line strength of reinforced plastic parts

摘要

SOLVAY Specialty Polymers has conducted an extensive study that supports the use of overflow tabs as a method to improve weld line strength of injection molded structural components. The technical study, which examined structural parts made of Solvay's KetaSpire polyetheretherketone (PEEK) and AvaSpire polyaryletherketone (PAEK) resins, revealed a minimum increase of 50% in flexural strength for all materials using two-gate designs with an overflow tab compared to two-gate samples with no tab.
