Profile: Plas-Tech Thermoforming Ltd. specializes in manufacturing engineered vacuum formed plastic components. We also offer services like thermoforming, drape forming, press moulding, CAD service, fabrication, CNC machining and component assembly. Our vacuum forming is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature. It is stretched onto or into a single-surface mould and held against the mould by applying vacuum between the mould surface and the sheet.
