Abstract
1460101 Injection-moulding; cellular cored articles INSTITUTE PO METALOZNANIE I TECHNOLOGIA NA METALITE 9 May 1974 [9 May 1973] 20650/74 Heading B5A Articles having a non-cellular skin and a cellular core are formed from materials containing a blowing agent by firstly injecting the material into a mould at a temperature below that at which foaming takes place and then injecting a second batch into the mould at a temperature above that at which foaming takes place, the first batch forming the skin and the second batch the core. As shown in Fig. 1, the injection nozzle comprises parts 1, 5 connected by nut 4 and separated by electrically insulating rings 3. An electric heating element 2 is located on the axis of the nozzle with one end welded to part 1, the other end to part 5, and is controlled by supply/control block 7. The nozzle is attached to the plasticizing unit 6 of the injection machine.
