Why do flow and encapsulation matter for PVC plug molding compound?
PVC plug compound must match mold structure, molding temperature and overmolding needs to avoid short shots, sticking and surface defects.
PVC plug compound is used for power plugs, strain reliefs, connector overmolding and electrical accessories.
Unlike extrusion compound, it must fill the mold cavity quickly and encapsulate wires or terminals properly.
Poor flow can cause short shots, visible weld lines or high injection pressure. Excessive flow may cause flashing or poor hand feel.
Buyers should provide product photos, mold or processing conditions, target hardness, color, flame-retardant grade and compliance requirements.
