Abstract

712,276. Moulding processes; mould materials. REGIE NATIONALE DES USINES RENAULT. July 14, 1952 [Sept. 5, 1951], No. 17758/52. Class 83 (1) In a lost wax method of moulding, the investment of a coated pattern is carried out in two stages ; firstly a solution of a binder is poured into the moulding box followed by the sand or other refractory material. The wax pattern 2, 3 is placed in a moulding box 1 on a vibrating table 5 and a solution of sodium silicate and ammonium nitrate is poured in. There is then added from a sieve 6 of 30 meshes per inch, white sand of 40-140 mesh comprising 99 per cent silica. Alternatively there could be used a sand containing 2-4 per cent clay or aluminium or silicoaluminous refractory materials. This is left for two hours, dried for 24 hours at 70‹ C., then for 16 hours at 100‹ C. and then heated up to 850‹ C.
