Due to the great demand for plastic processing, our firm offers you a wide range of machinery specialized in specific products (pipes, profiles, squares, straws, spirals, etc.), with one or more cavities, in addition to compatibility with a large list of materials such as PP, PE, PVC, HDPE, HIPS, PMMA, PP-R, ABS, PA NYLON and many more.
Plastic extrusion process consists of forcing a molten material (polymer) to pass through a die, which forms a continuous profile that is cooled and solidified. Typically this process is profitable for high production volumes. One of the advantages of this process is the creation of pieces of great length and with many and diverse possibilities.
The main plastic extrusion processes are:
Blown film extrusion
Also called “tubular film”. This process combines extrusion and blowing to produce a thin film film. It begins with the extrusion of the tube film, which is stretched towards rollers and at the same time expanded by air to a mandrel. The film to make the bags and the sheets / plates are made by this method.
Sheet and film extrusion
Used for extruding plastic sheets and film films that are too thick to be manufactured by the above method. The molten material is extruded through a flat die. It is then stretched through a set of chill rollers that are used to determine the thickness and texture of the surface.
The molten material is extruded through a die with a mandrel, forming a hollow section.
This process allows the application of an outer layer of plastic on a wire or cable that exits through the center of the die.
