Extrusion is a high efficiency, continuous, low cost, suitable for the surface width of the forming process. The main process is the material through the extruder cylinder and screw between the role, the side is thermoplasticized, the side is pushed forward by the screw, continuous through the head to make a variety of cross-section products or semi-products. Extrusion is suitable for most plastic materials except some thermosetting plastics, and about 50% of thermoplastic products are completed by extrusion molding.
┊ Addition: Add plastic raw materials to the extruder barrel.
┊ Melt Plasticization: By heating and mechanical action, plastic raw materials are gradually melted and plasticized.
┊ Extrusion molding: Driven by a screw, the melted plastic passes through the head mold to form a continuous profile with a certain cross-section shape.
┊ Shaping and cooling: The extruded profiles are shaped by a shaper and then cooled by a cooler to cure them.
┊ Low cost equipment: Extrusion equipment is relatively simple and low cost.
┊ Easy to operate: The process is easy to control for continuous automated production.
┊ High production efficiency: Large quantities of continuous products can be produced quickly.
┊ Product quality is uniform and dense: Due to uniform plasticization and extrusion in the extrusion process, product quality is more stable.
┊ A wide variety of shapes can be formed: By replacing the head die, a wide variety of products with different cross section shapes can be produced.
