Reasons for the Different Color in the Surface of Roof Tile

Technology Reason for Co-extrusion

When ASA co-extrusion material is used in resin tile, the uniformity of co-extruded surface is a very important quality index. Generally, the thickness of co-extruded layer is about 10-15 filaments. In order to save the cost without affecting the uniformity of the coextruded layer, the phenomenon of different thickness cannot occur. Uneven thickness from visual inspection, it can be observed that the overall color of the coextruded surface is different, and there is a feeling of "flower". At this point, don't panic, you need to check the heating parts of the equipment, such as the distributor heating part and the mold heating part, to check if the temperature is overheated or too low.
