Modern manufacturing methods in plastic materials

The paper is based on considerable experience of practice in Britain, on the Continent and in U.S.A., and special care has been taken to avoid material already covered in papers published in the June, 1938, issue of the Journal. The chief items covered include Phenol material and fabrication, extrusion of phenol and urea materials, acetate materials, laminated sheet material, moulds and plant. In the discussion reference is made to the use of plastics in motor car and aircraft construction.
