AH Series
High resin flow, low shear stress
The resin flow through the gate area is smoother, reducing molecular pressure and fragmentation of the resin, therefore reducing shear stress. The piston is a specially shaped design which seals the gate precisely and prevents back flow from the cavities.
Features
Engineered advantages
01
Durable, Low Maintenance Design for High Volume Production
FISA's patented internal structure is a durable, low maintenance design for high volume production.
02
FISA's Patented Valve Mechanism
Patented, internal spring design utilizes resin pressure for actuation of the gate.
03
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.
04
Preventing the Backflow of Resin
The piston is a specially shaped design which seals the gate precisely and prevents back flow from the cavities.
05
Compatibility to NH Series
Compatible with most NH applications for retrofitting.
