Abstract
An edge-casting process for sheet materials according to the present invention includes the following steps: S1. grooving, that is to choose a suitable sheet material, and leave a processing margin on the peripheral edge of the sheet, material, so as to make a first groove; S2. casting or covering, that is to cast a high solid content coating material into said first groove and solidify it; S3. making a second groove on the back of said first groove of the sheet material, and casting a high solid content coating material into said second groove and solidify it; and S4. milling and chamfering, that is to chamfer the sheet material according to a required processing margin, then perform an edge-casting process. An objective of the present invention aims to simplify processes, improve production efficiency, upgrade edge banding performance, greatly enhance the waterproofness, super hardness, anti-friction, collision resistance and adhesion of sheet materials, and dramatically extend the service life of sheet materials, therefor we provide an edge-casting process for sheet materials and its application capable of producing cast edges of variously-shaped sheet materials and suitable for…
