Completely prevent wire drawing and drooling of injection molding machines
Model NR is a needle valve nozzle used in thermoplastic molding machines and is a reliable needle valve gate system. It is widely used by various molding machine manufacturers.
Features of the NR series
- POINT2
- prevent wire drawing
- POINT3
- prevent salivation
- POINT6
- Built-in strong spring
1. Prevent backflow from the mold cavity
- The built-in strong spring allows the valve pin to completely close the gate without causing backflow of resin
2. Prevent wire drawing problems
- In particular, it is very effective for resin molding with good fluidity.
3. Prevent salivation problems
- The gate is completely closed, reducing the generation of cold material and improving the quality of molded products.
4. Improve instant shot rate
- The resin in the nozzle is injected under pressure to increase the filling speed.
5. Structure without stagnant space
- The resin flow path in the nozzle is streamlined and has no residual resin to prevent burning problems.
6. Built-in strong spring
- The use of super alloys improves durability through advanced heat treatment technology.
