Itself cannot produce bubbles out of thin air. It introduces butane into the barrel, which is fully mixed and extruded by the screw. at a certain temperature, it realizes the contact surface between liquid and gas as large as possible to form bubbles.  

There are many brands and types of foaming machines, but according to the foaming thickness, 75 machines, 90 machines, 105 machines, 120 machines, 135 machines, 150 machines, 170 machines, 180 machines and 200 machines are widely used at present. According to the shape of foamed products, foamed sheets, foamed pipes, foamed bars, foamed corner profiles (such as L-shape and U-shape), foamed round bars, foamed laths, etc. Are currently applied, but there are differences in their auxiliary equipment and automatic control.
