Sprue Bushings

The Integrally Heated Sprue Bushing is uniquely designed for high performance and reliability for Manifold and Direct Feed Applications, even with the most demanding molding cycles and plastic resins. The advanced heat transfer capability is attributed to its integrally heated design, resulting in a more uniform heat profile. A replaceable thermocouple is strategically located close to the melt flow channel for optimization of processing conditions with all thermoplastics.
