Title: METHOD FOR MANUFACTURING RESIN PRODUCT
Abstract:
A method for manufacturing a resin product having a plurality of thread-like protrusions on a contact surface of a resin product body part thereof comprises: a step of pressing a tip end, which is formed to have an acute angle, of plate-like metal (21) into a contact surface (12f) of a resin product body part (12); a heating step of heating the plate-like metal (21) before or during the pressing step; and a step of pulling out the plate-like metal (21) in a state in which resin material of the resin product body part (12) around the tip end of the plate-like metal (21) is melted and resin material around molten resin (12m) is solidified. In the pulling-out step, the molten resin (12m) attached to the tip end of the plate-like metal (21) is stretched in thread form to form a protrusion by being pulled away from the molten resin (12m) of the resin product body part (12).
