he extrusion process can be further customized to meet different product requirements. Here are some variations in PVC profile extrusion: A.Co-extrusion involves using two or more materials simultaneously to create a multi-layered profile. For example, a rigid inner layer with a flexible outer layer can enhance the product’s durability and aesthetics. B.Tri-extrusionTri-extrusion is a more advanced process that utilizes three types of materials. This technique is especially useful for producing profiles requiring multiple characteristics, such as UV resistance, insulation, and flexibility.C.Post-extrusion Processing.Some PVC profiles require additional treatment after extrusion, such as embossing, coating, or laminating, to enhance their aesthetic or functional properties.
