Drool Protection

Even with attentive maintenance and routine equipment inspections, almost all injection molding machines occasionally extrude plastic drool, or “blow back.” Plastic drool has an unattractive name for a reason; it can lead to extended periods of downtime for cleanup or significant damage to equipment.
