Plastic Extrusion Manufacturer

Extrusion of plastics is produced by a process known as plastic extrusion. Plastic extrusion is a manufacturing process in which plastic raw materials are melted down and formed into a continuous profile. 

Plastic extrusion produces all types of different items and is particularly useful for the manufacture of window frames, tubing, pipes and weather stripping. Know more about the Plastic Extrusion via  http://limaextrusion.com/en/.

To expel the plastic into various shapes, called raw thermoplastic resin material in the extrusion industry, and in the form of small beads, loaded into a gravity hopper mounted on the top of the barrel of the extruder.

Forcing screws or plastic resin beads along the barrel is heated to the desired temperature and can range from 200 degrees Celsius, about 275 degrees Celsius.

Temperature controlled barrel along its length so that the beads move along the temperature will increase. The gradual warming of the resin makes it possible to melt gradually and evenly as forced together through the barrel and minimize the risk of overheating, which in turn can cause the polymer to degrade.

Leaf plastic screw on the front end of the barrel and passing through the screen pack to remove any contaminants that may be present in the plastic melt.

The end of the heated product is then cooled by water drawn through the bath. When compared with some metals, plastic conducts heat away approximately two thousand times slower, because the plastic is a highly efficient thermal insulator.
