Abstract: 819,393. Moulding-processes. BRISTOL AERO-ENGINES Ltd. April 3, 1958 [April 4, 1957], No. 11059/57. Class 83 (1). A method of making a hollow shell-like article consists in forming a coating, of a non- metallic powdered material mixed with a bonding material, on a pattern, forming an additional coating of a metal readily heatable by a highfrequency electromagnetic field, and then melting out the pattern through a hole in the shell by the use of such a field. The iron, nickel or chromium metal coating may be formed by sticking on to the shell, by petroleum jelly, gum or resin, metal powder of at least 60 mesh/inch size, the coating being removed subsequently by brushing, by blowing or magnetically. Alternatively, the shell and pattern may be placed in a fireproof container and surrounded with metal powder of 24 mesh/inch size. If it is not important to remove the metal coating, it may be incorporated as an intermediate layer in the shell. In an embodiment, a wax pattern embodying a runner portion having a metal core embedded therein is coated, except over a pouring gate portion, with alumina of 200 mesh/inch size and an aqueous sodium-silicate solution. A layer of average 50 mesh/inch size coarse alumina is then added. After several such layers have been formed, the pattern is dipped in an aqueous sodium-alginate solution and covered with 48 mesh/inch iron-shot grit. The pattern is then lowered, runner downwards, into an electromagnetic field. When all the wax has run out, the shell is fired for up to 2 hours. It may be backed up with sand during pouring.
