uPVC Profile is a door and window frame fan made by cutting, welding or screwing, so what are the coloring methods for plastic steel profiles?
1.Two-color co-extrusion method
The two-color co-extrusion method is the most advanced and mature technology in the world for the production of colored profiles. The two-color co-extrusion method is actually a composite technology in the general white profile extrusion molding process. Composite materials generally include colored organic glass (PMMA), ternary composition ASA and colored PVC masterbatch. Among them, the design and manufacture of abrasive tools are more complicated, and each profile requires a set of abrasive tools, which requires a high one-time investment.
2. Whole body shading method
The whole body coloring method is to mix the coloring pigment into the blended powder of the profiled material or formulate it as a liquid and add it from the exhaust port of the extruder to obtain the coloring method of the whole body color profiled material. It has the advantages of small investment, convenient production process, and low scrap rate. In addition, this coloring method is also prone to uneven color or fading.
