Cold stamping, also known as press working,^[1] is a manufacturing operation where thermoplastics in sheet form are cold-formed using methods similar to metals.^[2] A precut thermoplastic sheet, either reinforced or unreinforced, is softened by heating the sheet to a temperature particular to the plastic in use. The heated sheet is then shaped by stamping using a press.^[3] Fiberglass-reinforced thermoplastic sheets are formed using metal stamping presses after the sheets are preheated to about 200°C (392°F).^[2]
