Abstract

1,193,141. Sheet forming. ZENTRALLABORATORIUM FUR PLASTVERARBEITUNG. 10 May, 1967, No. 21629/67. Heading B5A. Hollow articles are deep drawn from hot injection moulded blanks the peripheral regions of which have been cooled to a greater extent than the central regions. In the embodiment shown, a blank is injection moulded in a mould comprising upper and lower halves 1, provided with cooling channels 2, and edge defining frame members 3, provided with cooling channels 4. After injection, the central part 6 is cooled to temperature at which it is plastic whilst the edge 5 is cooled until it has set rigid. The mould halves 1 are then removed and the blank, still held by members 3, deep drawn using suitable apparatus (see Fig. 2, not shown).
