Extrusion molding is a processing method which can be formed by heating, pressing and making the material flow in a continuous way through a certain shape. Extrusion molding in the plastic processing field accounted for a large proportion of the world's more than 60% of plastic products are processed by extrusion processing. Almost all thermoplastics can be by means of extrusion molding processing, in recent years with the extrusion molding equipment development, extrusion molding is used in the part of another thermosetting plastic processing. Extrusion molding products made of cross section is the size of the continuous material, such as pipe, profile, sheets, film, fiber, wire and cable and extrusion of plastic parison and.

The casting method is a method for preparing thin films. Manufacturing, the first liquid resin or dispersed disseminates in carrier (metal band) on, followed by a proper method will aging it, finally you can from the carrier strip take the film. Thermoforming plastic sheet extrusion and casting can be combined to prepare high performance.

Extruder heating, pellets, powder, crushing material or return to the mixture, exhaust, and under pressure from the slit die extrusion. According to the thickness of the plastic type and material, hot extrusion is pull and stereotypes, or pushed with cooling of the synchronous rotation of the traction roller (roller cooling process). A cooling section, and then cut the edge, and take the. Sheet material cutting. Single and composite molding materials can be produced. General extrusion function production of the material range from 0.1mm thick film to 50mm thick x2000mm wide sheet, and even the width of up to 5000mm.
