Dual Zone Integrally Heated Sprue Bushings
The Equatemp® Dual Zone Integrally Heated Sprue Bushings are unique designs incorporating individual head and nozzle body heaters, allowing for more accurate control to yield a more consistent thermal profile, essential when processing tight tolerance engineered 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.
Topless, Full Body & Sprue tips
FEATURES & 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
Fully sealed construction – for increased reliability
High-grade alloy steel construction – for increased durability
SPRUE TIPS – for use where gate vestige is allowed. Provides low resistance to flow with excellent flow rates. Extended style provides additional stock for machining profiles or part contours.
Full Body – Ideal for low vestige commodity and engineering grade resin applications. The Full Body features a sealed tip for efficient shut-off at the part surface. Available with standard or wear resistant needles. Extended style provides additional stock for machining profiles or part contours.
Topless – Suitable for high viscosity resins, engineering plastics and applications requiring optimum gate cosmetics with minimal gate vestige. Available with standard or wear-resistant needles.
