A radical change has been realised on the BHP-nozzle type. This nozzle which is activated either by a hydraulic or pneumatic system has the big advantage of a large and straight-lined melt flow channel. Therefore the shear impact on sensitive materials is minimized and pressure loss is considerably reduced.
The core parts of the nozzle are manufactured to cope with considerable abrasion and use the most upto date coating technologies together with high-quality steel. The nozzle can be deployed for operating conditions of up to 3000bar at 400°C process temperature. This shut-off nozzle type can be adapted to any kind of injection molding machine. Customized nozzle tips can be manufactured according to customer specific dimensions. Typical fields of application are: shear sensitive materials, high injection rates and hot runner applications.
