Brief Analysis of the Reasons for the Surface Roughness of Co-extruded Resin Tile

The provided video is merely a demonstration of how ASA roof tiles are produced. There are no issues with the products shown in the video

1. The drying time and temperature settings are not in accordance with the process requirements.

• • The drying time and temperature settings should comply with the performance of the co-extrusion material used, especially in terms of water absorption and volatility. Our company provides drying time and technical parameters for ASA material. For example, if the drying conditions for ASA are set at 95-98℃ for 1.5-2 hours (hot air drying), failure to meet these requirements may result in surface “bubbling” and a rough texture during co-extrusion.

2. The vacuum system of the main tile machine is malfunctioning.

• • When the main machine’s vacuum system malfunctions during the formulation of tiles, the moisture and volatile substances present in the tile mix may cause “bubbling” during molding. The co-extruded layer may appear uneven, resembling a “raining-sand-beach-surface” looking, leading to an unattractive appearance.
