Rubber foam insulation board extrusion line is mainly used to extrude all kinds of foamed or non-foamed rubber pipes, plates, handles, sheaths, profiles, seals, etc. Huashida Rubber foam insulation board extrusion line is mainly composed of rubber cutting machine, mixer, feeding device, opening machine, rubber extruder, die, far infrared vulcanization box, hot air vulcanization box and traction cutting device.
Huashida Rubber foam insulation board extrusion line features: extruder screw is divided into feeding section, compression section, throttling section, exhaust section and extrusion section. In the throttle section, shallow grooves with equal distance and equal depth threads are adopted, which can make the rubber obtain higher shearing and stable conveying process, and improve the exhaust effect at the same time.
