Abstract

PURPOSE: To carry out draining without water droplets remaining on the surface of the molded item when draining a plastic molded item having a contact angle with water over a specific value after water washing, by drawing it up in a vertical direction at a specific speed corresponding to the water temperature of a washing tank.
CONSTITUTION: A plastic molded item having a sheet or lens shape and a contact angle with water over 45° at 20°C is washed with water before applying paints to remove foreign substances such as dust and refuse adhering to the surface of the item, and thereafter the molded item is drained by drawing it up vertically. When draining the molded item in such a fashion, it can be drained without water droplets remaining on its surface by drawing it up under conditions as set forth within an oblique line part formed by lines connecting points A, B, C, D, E and F in a graph showing a relation between the water temperature of a water tank and the drawing up speed of a molded item. Polystyrene, PVC, etc. are mentioned as examples for plastics having a contact angle with water over 45° at 20°C.
