- Core injection notebook cover (PC + ABS)
- Valve gate system use only.
- Excellent gate vestige.
- Simple operation of a valve pin.
- Application for a wide range of applications with both general purpose and engineering materials.
- Compact design with 3 optional channel diameters.
- Helps simplify stack mold structure and operation.
- The valve pin moves vertically inside of nozzle body by a position without any use of ratchet or rotating cam mechanisms.
- The creative single valve series nozzle offers 3 standard flow channels with gate diameters from 15 mm to 8 mm, and an optional size up to a maximum of 10 mm diameter gate.
- The length of the nozzle can be up to 1000 mm, and provides the best solution for feeding the component through the fixed half core.
- The smart flow channel offers excellent color change, in less than 10 shots, and a large injection volume with lower injection pressures.
Hot Runner Valve and Nozzle system
|- Yuri system is a patented technology featuring the valve mechanism and nozzle constructed as one unit.
- The smart flow channel minimizes the pressure drop in the nozzle and facilitates quick and easy color change.
