NR Series
The PLAGATE barrel shut-off nozzle
The NR type PLAGATE barrel nozzle is of the same patented design as the NH type — a shut-off nozzle that exhibits outstanding performance when used for the injection molding of high flow resins.
Features
Engineered advantages
01
Prevents the Backflow of Resin from the Cavity
When the gate is in the closed position, backflow of the molten resin is prevented by means of the piston.
02
100% Prevention of Stringing
The Plagate shut-off nozzle exhibits outstanding performance when used for the injection molding of high flow resins, such as polypropylene and nylon.
03
Prevention of Drooling
Zero vestige due to the valve gate seal, leading to enhanced quality.
04
Improved Injection Rate
The molten resin in the cylinder is pressurized and flows into the Plagate shut-off nozzle. This works as a simple accumulator, and speeds up the filling process.
05
No Dead Space
All flow channels in the Plagate nozzle are streamlined in design, preventing the retention of molten resin, as well as scorching, burning, or overheating.
06
Strong Spring
The spring is made of a super alloy steel and is precision tempered, making it strong and remarkably durable.
