Description
Polyshot has raised the bar on “in line” pneumatic direct valve gating. With its extremely high pin force of 400 lbs. The Polyshot Single Nozzle Valve Gate makes light work of processing the most highly filled and unfilled commodity resins. In a unique feat of engineering, it places the pneumatic actuating cylinder within the integrated mold locating ring.
The Polyshot Single Nozzle Valve Gate System is designed to be the most compact and mechanically reliable unit available.
We accomplish this by using fewer components than the competition and containing the activation within the mold locating ring. We have also designed all components to move in an inline action which greatly reduces wear.
We have manufactured this unit with the customers needs in mind. With its’ compact size and the ability to easily change nozzles, it can be used for a variety of applications. So whatever your production needs are, whether it be a high production mold or prototype tooling, the Polyshot Single Nozzle Valve Gate has you covered.
