Molding of thermosetting polymers to specific shapes by heating a thin sheet then pulling it against a pattern with a vacuum
A method of making a face mask where a thin piece of plastic is heated and then drawn around a positive face mold or into a negative face mold by vacuum. The resulting plastic face piece is usually covered with cloth.
A forming process in which a heated plastic sheet is changed to a desired shape by causing it to flow by reducing the air pressure on one side of the sheet. Method of sheet forming in which the plastic sheet is clamped in a stationary frame, heated and drawn down by a vacuum into a mold.
A process whereby a heated plastic sheet is drawn against a mold surface by evacuating the air between it and the mold.
Method of forming sign faces in which a plastic sheet is clamped in a stationary frame, heated and forced down by a vacuum onto a mold.
Technique for molding plastic sheets by heating and drawing sheets in a vacuum press.
a process using thin plastic sheet which is formed around a mould using atmospheric pressure used in blister packaging
A method of forming plastic sheets or films into three-dimensional shapes, in which the plastic sheet is clamped in a frame suspended above a mold, heated until it becomes softened, drawn down into contact with the mold by means of a vacuum, and cooled while in contact with the mold. Often used interchangeably with thermoforming.
Method of sheet forming in which the plastic sheet is clamped in a stationary frame, heated, and drawn down by a vacuum into a mould. In a loose sense, it is sometimes used to refer to all sheet forming techniques, including Drape Forming involving the use of vacuum and stationary moulds.
Vacuum forming, also known as thermoforming, is a process in which heat is applied to a thermoplastic sheet that is then pressed into a mold and a vacuum is drawn to force the plastic into the shape of the mold.
A process whereby a print on a plastic sheet is heated and distorted over a mould by air pressure. Used for embossed or relief prints, and producing 3D items such as blister packs, cycle helmets.
Vacuum forming is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto or into a single-surface mold, and held against the mold by applying vacuum between the mold surface and the sheet.
