Vent type Rubber Extruder
The special design screw is necessary for vent type rubber extruders
It is available each size of vent type rubber extruder with a vacuum pump which has a function to forcibly remove the air caught in the kneading process or the rubber input part or the moisture contained in the air from the vent hole (degassing hole) provided in the center of the cylinder.
With this function, the air that causes air accumulation and pinholes in the product can be removed as much as possible. This is an essential function for thin-walled products and products that are continuously vulcanized at normal pressure.
