Dual Zone Integrally Heated Sprue Bushings

The Equatemp® Dual Zone Integrally Heated Sprue Bushings are unique designs incorporating individual head and more nozzle body heaters, allowing for accurate control to yield a more  consistent thermal profile, essential when processing tight tolerance engineering resins.

Three-tip designs provide flexibility for direct or runner gating, and the full body and topless tips are available with either standard or wear-resistant needles. The “extra-stock” style sprue bushing tips provide additional material for machining profiles or part contours. A replaceable nozzle thermocouple is located at the tip and near the melt flow, improving controllability.
