Abstract

1,150,052. Injection moulding. M. HUBEL. 7 June, 1967 [1 April, 1966], No. 14475/66. Heading B5A. In a process of making panels a metal sheet 54 is supported against distortion and a layer of thermoplastic material (e.g. P.V.C. or A.B.S.) is injection moulded thereagainst to bond to and cover a surface of the sheet. During a first injection stage the sheet 54 is supported by a magnetic insert 4 and by rods 29 pressed upwardly by a slide 35. When the mould is filled the slide 35 is moved to the right in Fig. 3 by a hydraulic cylinder 41 and the rods 29 are moved downwardly clear of the mould cavity by springs 31 acting on plungers 28. The lower ends of the plungers 28 have domed projections 32 which co-operate with recesses 37 in the slide 35. The surface of the metal sheet may be pretreated by spot or sand blasting or chemical etching, and may be pre-coated with a sprayedon solution of a thermoplastic material. The injection moulded layer may extend around the edges of the sheet, or both sides of the metal sheet may carry an injection moulded layer. The two layers may have different colour or surface texture. Injection may be effected centrally of the panel or through a sprue bush arranged between mould parts 1 and 26. The injection mould may be formed by pressing dies used for initial shaping of the metal sheet.
