The present invention is aimed at providing a manufacturing method for eyeglass frames including heterogeneous materials, and eyeglass frames manufactured using the same. The manufacturing method removes delamination by combining: a polyamide injection-molded material comprising thermoplastic engineering plastic which has excellent shape restoration properties; and an acetate solid pattern sheet. Thereby, the eyeglass frames manufactured by the present invention are high quality. The manufacturing method for eyeglass frames including heterogeneous materials of the present invention comprises: a step of cutting the acetate solid pattern sheet along a design pattern prepared in advance; a step of softening the solid pattern sheet by immersing the solid pattern sheet cut along the design pattern in the softener; a step of joining heterogeneous materials and simultaneously restoring the solid pattern sheet using one of two methods, one of which is hot-pressing after bonding the softened solid pattern sheet to a selected position of the polyamide injection-molded material for eyeglass frames prepared in advance using the adhesive, the other of which is implementing one process chosen from a group of processes including a hot melt fusion process, a heat fusion process, a high-frequency fusion process, and an ultrasonic wave fusion process; a step of surface-grinding the heterogeneous materials of the eyeglass frames in a barrel that have been dried and were manufactured by combining the acetate solid pattern sheet and polyamide injection-molded material; and a step of implementing the top coating on the surface layer of the heterogeneous eyeglass frames. |
