55 gallon barrels Blow Molding Machine

This is a 55-gallon chemical barrel filling machine that can produce single-layer products. Blow molding principle Blow molding barrel making consists of two parts: extrusion and blow molding, which are collectively called barrel extrusion-blow molding. Blow molding barrel making is that plastic particles pass through the hopper mouth and are heated by the three-stage heating zone barrel to melt them. The molten plastic is extruded into a tubular parison through the filter screen, porous plate and die head under the extrusion of the screw thread. Then, the parison is clamped into the mold to be blown while it is hot, and compressed air (hereinafter referred to as wind) is introduced to inflate it to reach the shape of the mold cavity. After a certain time and wind pressure are maintained, it is cooled and shaped, and the fixture is opened to obtain a finished barrel (sometimes trimming is required).
