Molding manufacturing method and apparatus |
摘要 |
A molding manufacturing method includes: preparing a molding body including a molding main body made of thermoplastic material and a decorative layer higher than the molding main body in hardness and melt temperature; setting the molding body in a fixed die; heating and softening an end portion of the molding body while maintaining the decorative layer softer than the molding main body, by irradiating an infrared ray onto a back surface of the molding main body corresponding to the end portion; and press forming the end portion of the molding body by applying a movable punch onto the fixed die while the end portion of the molding body is in a softened state to bend the end portion of the molding body to obtain an end cover portion having a predetermined shape.
