  • Publication number: 20210064150
    Abstract: A process for forming a two layer plastic device with textures or drawings thereon and a structure formed by the structure are provided. An inner bottom layer has textures or drawings on the surface thereof which includes at least one enclosing space. A through hole is formed on the enclosing space so that the masking material can be filled into the space between the outer mold and the inner mold. Then the masking material enters into the enclosing space through the through hole. As a result, only one mold (the outer mold) is necessary for forming the masking layer, while in the prior art, two molds are needed. The whole process can be completed mechanically without any manual operation. A color of the masking layer may be different from that of the inner bottom layer so that the textures or drawings clearly exposes on the surface of the masking layer.
