Abstract

본 발명은 불투명 또는 유색 합성수지재 사출성헝물 표면에 투명합성수지재가 씌워진 상태로 사출성형하여 주므로서 불투명 또는 유색사출성헝물이 외부에서 선명하고 입체감있게 관측되게 하므로서 불투명 또는 유색합성수지재충이 보다 명확하고 선명하게 외부표출 관측케 한 투명수지 및 불투명 또는 유색수지로된 이중사출 성형방법 및 그 성형제품에 관한 것으로 표면과 본체를 성형하기 위한 하측금형과 숫자, 문자 및 도형을 성형하기 위한 돌출부 및 돌조성형 요입부가 성형된 상측금형을 상호밀접되게 고정시키고 상측금형에 투명합성수지액을 충입하여 탈형시킨후 가압면에 평할면인 또다른 상측금형을 밀접교정하면서 불투명 또는 유색수지액을 충입경화시켜 되는 투명수지 및 불투명 또는 유색수지로 된 이중사출 성형방법 및 그 성형제품인 것이다.In the present invention, the opaque or colored synthetic resin material is injected into a transparent synthetic resin material coated on the surface of the opaque or colored synthetic resin material, so that the opaque or colored synthetic resin material is observed clearly and three-dimensionally from the outside. The present invention relates to a double injection molding method of transparent resin and opaque or colored resin, and its molded product, which are externally exposed observation, and a lower mold for forming a surface and a body, and a protrusion and a protrusion for molding a number, letters, and figures. The transparent resin which is fixed by additionally fixing the upper mold to be in close contact with each other, filling the upper mold with a transparent synthetic resin solution and demolding the mold, and then hardening the opaque or colored resin solution by injecting and hardening another upper mold which is a flat surface on the pressing surface. Double injection molding method of opaque or colored resin and molding It will pumin.
