Abstract

1378493 Injection moulding valve parts SERCK INDUSTRIES Ltd 2 Dec 1971 [8 Dec 1970 4 Aug 1971] 58162/70 and 36632/71 Heading B5A A method of making a lined body of a fluid control valve (Fig. 3), comprises the steps of inserting into a mould 18, 19, having a surface complementary to the required completed surface of the lining of the body, a lining shell 10 having a simplified surface such that cavities, as 22, remain between the mould surface and the shell, introducing a flowable and settable material into the mould at a pressure sufficient to form the shell into contact with the mould surface and causing the material to set. After the body is removed from the mould the set material 25 retains the shell in the desired shape. The mould part 18 has a collapsible core 20 and the mould part 19 a fixed core 21. The mould is used in, e.g. a transfer moulding press, synthetic resin material, preferably thermosetting, being introduced under pressure through gates 23, 24. The shell may be of P.T.F.E. and may comprise a main lining part 10 and a pair of sleeve parts 11, 12 for surrounding the spindle 16 of a butterfly valve. The injected material also forces parts 10c into intimate engagement with grooved end portions 11a, 12a of the sleeve parts 11, 12.
