Integrally Heated Hot Sprue Bushings



Integrally Heated Sprue Bushings .750" SERIES

The Integrally Heated Sprue Bushing is uniquely designed for high performance and reliability for direct gating applications, even with the most demanding molding cycles and plastic resins. The product’s advanced heat transfer capability is attributed to its integrally heated design, resulting in a more uniform heat profile. Maximum heat 600ºF. A replaceable thermocouple is strategically located near the melt flow channel to optimize processing conditions with all thermoplastics. Features and Benefits:

• Distributed watt density – maintains a more uniform heat profile. • High refractory insulation – provides superior heat transfer. • Streamlined flow channel – minimizes pressure loss. • Fully sealed construction – maintains highest product reliability. • High-grade alloy steel construction – increases durability and longer life. • Replaceable thermocouple – allows for Type “J” or “K”.
