By PVC fence and additional layer of colored material forming co-extrusion profiles. The color PVC material either zinc alloy fence, or poly (methyl methacrylate) or acrylic - styrene - acrylate copolymer (ASA) fence, we need two extruders hosts (cone rod 60 or 58 pairs of pupae and the single screw 30) to achieve. Production profiles must use a composite mold, the production process is from the profiles of two different materials and color material flow path, before leaving the bus into the same mold class late in common extrusion. Features of this method are: the production process need to reprovision cold mixer or dryer and other equipment zinc alloy green fence, material recovery difficult, complicated production process, high cost of composite membranes, large investment.
