Product Details

The word extrude consists of the Latin "ex" (away) and "trudere" (push), which graphically describes the extrusion process of "applying pressure to drive the material through the mold."

 

In processing, the polymer in the form of powder or granular form is usually added to the barrel of the extruder. Under the action of the screw or the plunger, the polymer moves forward along the groove or the barrel, and gradually melts and becomes sticky. The fluid is then formed into a continuous body similar in shape to the die of the mold through a mold disposed at the end of the barrel, and finally cooled and shaped to form a product of a desired shape, such as various plastic tube bars and sheets, plastic steel doors and windows, film, decorative skirting, etc.
