Composite process + composite mold; 3. Edge wrapping process + edge wrapping tooling (manual edge wrapping); this solution usually carries out edge wrapping after molding and composite, which can achieve the purpose of sealing the edge without white leakage and preventing scratching, but its cost is relatively high. Manual edge wrapping is not only costly and inefficient, but it is also difficult to achieve beautiful quality on the back, and the cost of mechanical edge wrapping tooling is even higher.
