Abstract
P.V.C. sheet is placed over the positive pattern. Gentle heating and vacuum are applied. Pressure is restored and the pattern is removed when the sheet has cooled down. The mould produced is used directly, without a separator material, to cast plastic articles. When the casting material is set it is free of air bubbles and has a silky finish.
