Abstract
Provided is a method of thermoforming a molding material to have a bent portion and a flat portion extending from the bent portion. The method includes: placing the molding material on a bending mold, the bending mold having a curved surface; and forming the bent portion of the molding material by heating a portion of the molding material at least to a fluidization temperature such that the portion of the molding material bends due to the weight of the flat portion of the molding material to form the bent portion according to a shape of the bending mold.
Claims14
A method of thermoforming a molding material by using a thermoforming apparatus, the thermoforming apparatus comprising a convexly curved bending mold and a concavely curved sliding surface, the method comprising:
- placing a flat molding material on the bending mold and over the sliding surface;
- and
- bending the molding material by locally heating a first portion of the molding material on the bending mold at least to a fluidization temperature such that the first portion of the molding material bends and an end portion of the molding material moves along the sliding surface due to the weight of a flat portion of the molding material to form a bent portion according to a shape of the bending mold.
A method of thermoforming a molding material, the method comprising:
- placing the molding material on a bending mold, the molding material having a flat portion, the bending mold having a curved surface;
- and
- forming a bent portion of the molding material by heating a portion of the molding material at least to a fluidization temperature such that the portion of the molding material bends due to the weight of the flat portion of the molding material to form the bent portion according to a shape of the bending mold,
- wherein the forming of the bent portion further comprises coupling a weight to the flat portion, the weight being pulled by a magnetic force of a magnet arranged along a rotation path of an end opposite to a center of the bent portion.
