Abstract
A manufacturing method for a refrigerator door is disclosed. The method uses only a transparent plastic layer to make the refrigerator door. The present invention can simplify the manufacturing process, and reduce the number of parts required for the refrigerator door to reduce costs. Furthermore, an appearance pattern on the refrigerator door can be painted or printed onto the surface of the transparent plastic layer with different types, and a male mold of a vacuum forming machine can provide different shapes to make the refrigerator door into variety shapes. Moreover, because the appearance pattern can be painted or printed on the inner surface of the transparent plastic layer, the appearance pattern will not come off because of frequent touching.
