Plastic extruder can do the work of extrusion. Extrusion process utilizes heat, pressure, and cooling to produce a semi-liquid, or paste, to be forced through a die, and after emerging from the die, hardened to a designated temper.
The extrusion process by the plastic extruder is used most frequently to form plastic products. Many plastic products can be formed with the help of a plastic extruder. Essentially, as long as a material can be easily liquefied, it can be extruded.
Extrusion processing by the plastic extruder is distinct from stamping or molding, for instance, in that the extruded material will form intricate, strong, and durable fittings, parts, and pieces from brittle stock that is difficult to shape through stamping, bending, or hammering. Additionally, the finished surface of extruded products made by the plastic extruder is consistently of higher quality than that of stamped or molded products.
In the case of the plastic process with the plastic extruder, this raw material is called pellets. The raw stock is fed from the hopper into the plastic extruder, essentially a heated cylinder, where it is softened. A ram, usually a worm gear, forces the semi-liquid raw material through a smaller chamber, then through a shaped die.
Extrusion process by a plastic extruder is one of the most common and popular technologies in recent years and it will get more applications in modern plastic processing industry.
