Manufacturing method of plate material for tooth cover tool, plate material for tooth cover tool

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a plate material for a tooth covering tool suitable for mass production of a wide variety of small quantities. SOLUTION: This is a method for manufacturing a plate material for a tooth cover tool used when manufacturing a tooth cover tool for covering a tooth, and a molten resin material is extruded through an annular flow path into a tubular shape. In the intermediate material generation step of forming to obtain the tubular intermediate material 14, and by sandwiching the molten tubular intermediate material 14 in the radial direction to weld the inner peripheral surfaces to each other, the inner peripheral surfaces are formed into a plate shape and cooled and cured. It is provided with a plate-shaped body forming step for obtaining a plate material for a tooth covering tool. [Selection diagram] Fig. 1
