Abstract

541,050. Injection moulding. KRAUSE GES., J. July 25,1939, No. 21553. Convention date, July 8. Addition to 518,294. [Class 87 (ii)] In apparatus for the injection moulding of thermo-setting plastic masses, according to the parent Specification, the mass enters the die, in the form of a liquid film, through a nozzle of such broad but flat cross-section that, in order to overcome the resistance offered by 'the nozzle, the mass has to be exposed to a feed pressure of at least 1,000 atmospheres. Objects manufactured by means of such an apparatus have greatly improved strength.
