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.

Features and Benefits:

• Separate, individually controllable head and nozzle body heaters - to maintain a more consistent thermal profile for more accurate temperature control
• Designed for engineered resins – higher temperatures and tighter temperature tolerances
• Integral heater insulation – improves heat transfer and efficiency
• Fully sealed construction – for increased reliability
• High-grade alloy steel construction – for increased durability
