Abstract

In moulding articles of, or covering them with synthetic resin-bonded fabric or other fibrous material, metal powder in the form of rounded particles is used to transmit heat and pressure from the mould walls to the article, thus obviating the necessity for shaping the moulds to the configuration of the articles. The powder used is preferably of a size to pass through a 20-mesh sieve. In covering a bar or rod, the bar is wrapped with cloth soaked in synthetic resin, and the cloth covered with a layer of tinfoil, aluminium foil, indiarubber or other suitable material. The assemblage is then placed in a mould which provides clearance on all sides and the intervening space packed with the metal powder. The packed mould is then placed in a heated press and heat and pressure applied to cure the resin. The metallic powder is stated to facilitate adequate control of the temperature of the resin, due to its conducting quality. For lining thin-walled boxes the metal powder may be placed round a central core or outside the walls of the box, the resin-soaked fabric being pressed outwards against the walls of the box in one case and the walls of the box being pressed inwards against the fabric in the other. Specifications 9043/03 and 19482/07, [both in Class 87, Moulding &c.], are referred to.
