High Resin Flow, Low Sheer Stress

The resin flow through the gate area is smoother, reducing molecular pressure and fragmentation of the resin, therefore, reducing sheer stress.

Preventing the Backflow of Resin

The piston is a specially shaped design which seals the gate precisely and prevents back flow from the cavities
Durable, Low Maintenance Design for High Volume Production

FISA’s patented internal structure is a durable, low maintenance design for high volume production.

FISA’s Patented Valve Mechanism

Patented, internal spring design, utilizes resin pressure for actuation of the gate.

Simple Mechanism

AH nozzles use a simplified design that allows shut- off on the diameter of the piston, eliminating the extreme precision fit of the NH series piston.

Compatibility to NH Series

Compatible with most NH applications for retrofitting.
