C. Jaroschek, NEW WAYS WITH THE SANDWICH METHOD OF INJE CTION-MOLDING - THE MONO-SANDWICH METHOD OF INJECTION-MOLDING FOR REGENERATE PROCESSING, Kunststoffe, German plastics, 83(7), 1993, pp. 519-521
A precise analysis of the sandwich method of injection moulding has sh
own, that the processing sequence is facilitated considerably, if both
melts are kept in readiness in a single cylinder for the injection pr
ocess. Little effort is needed in the way of equipping the machine for
this mono-sandwich method of injection moulding.
