A thermoforming device includes: an upper hot plate including a first heating surface configured to heat a sheet from above; a lower hot plate including a second heating surface configured to heat the sheet from below; and a substrate-supplying unit including a base configured to hold a molded substrate, and configured to attach the molded substrate to and detach the molded substrate from the base and to dispose the molded substrate at a molding position below the first heating surface with the sheet interposed therebetween, in which the upper hot plate and the lower hot plate are configured to heat the sheet simultaneously from an upper surface and a lower surface of the sheet, the lower hot plate is provided to be movable in a horizontal direction with respect to a position below the upper hot plate, and the thermoforming device die-molds or adheres, onto the molded substrate held by the base, the sheet softened by being heated by the upper hot plate and the lower hot plate.

Thermoforming device and thermoforming method

A thermoforming device using a hot plate heating includes a frame; a hot plate; a decompression unit connected to the frame; a decompression unit which is connected to a hot plate; a unit which is connected to the hot plate and opens a heating surface side to an atmosphere or pressures the heating surface side; an adsorption and heating control unit which performs the adsorption and heating operation of the sheet by the hot plate; a decompression control unit which performs a decompression operation in the concave portion; and a molding operation control unit which concurrently performs the adsorption and heating operation and the decompression operation, stops the adsorption and heating operation of the sheet after a predetermined time from the start of the operation, and opens a portion between the hot plate and the sheet to the atmosphere or pressures the portion.

An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure includes the steps of: compressing and deforming the multilayer structure, while extending respective layers of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion A of the push cutter and the cutter receiving portion.
