Cold Slug Injection Molding: What It Is and How to Avoid It
Cold slug injection molding, a pervasive challenge in thermoplastic processing, arises from the unpredictable solidification of molten polymer at the nozzle's terminus. This phenomenon, far from a simple defect, presents a complex interplay of rheological, thermal, and geometric factors, leading to the ejection of solidified polymer fragments – the "cold slugs" – into the mold […]
