Title: Hollow blow-mouldings prodn. - from partly blown pre-forms at a temp. giving biaxial orientation
Inventor: DEHNERT GOTTFRIED
IPC: B29C49/64
Filed: 1975-04-17
Abstract: In the multistage prodn. of blow-moulded hollow bodies by first moulding a pre-form from a tubular parison in a pre-forming mould and thereafter moulding a finished hollow body of the desired shape and size from the pre-form by introducing a pressure medium through a blow and calibrating mandrel, the pre-form coming from the pre-forming mould and held on the blow mandrel is subjected to a tempering process in an intermediate station before its introduction into the finishing mould. Enables the final blow moulding to take place at a uniform temp. just below crystalline m.pt. so that the molec. orientation thus taking place during expansion gives a product of exceptional strength and, if transparent, of exceptional clarity. The intermediate tempering is speeded up by the initial partial blow-moulding since the thinner walls permit more rapid temp. equalisation throughout, local temp. differences being removed by local heating or cooling.
