Abstract
The invention discloses a process method of a civilian LED convex mirror. The process method comprises: placing polymethyl methacrylate in a specially-made injection molding machine, carrying out melting treatment at a temperature of 200-250 DEG C, and respectively and separately molding in a specially-made mold at a temperature of 60-90 DEG C to form the civilian LED convex mirror, wherein the specially-made mold is provided with two (more than two) molding cavities. According to the present invention, the process method uses the specially-made machine, only one injection table is additionally arranged in the same type of the machine, and the mold is specially made, such that the production efficiency (compared to the product using the multi-cavity mold) is increased by twice, the production efficiency of the civilian LED convex mirror is improved, and the method can be widely applied in the field of civilian LED convex mirror.
