  • Patent number: 6757954
    Abstract: A method for manufacturing a colored plastic cutting board with anti-bacteria effect is disclosed. A pressing machine has material suppliers for supplying plastic material from an opening. The lower anti-bacteria layer and the middle supporting plate are outputted from an output. The lower anti-bacteria layer and the middle supporting plate are placed upon a substrate. Then they are transferred to be under a roller; and then a printing film is coated upon a top surface of the middle supporting plate. The printing film is printed with pattern. Then the cutting board is transferred to another pressing device which feeds a top transparent protecting layer upon the printing film. Then, the substrate is sent to a punching device for being punched so as to form a cutting board which has a fixed shape. Thereby, the process of printing and anti-bacteria can be performed continuously.
