PROCEDURE FOR ESTABLISHING PET UNDERTAKINGS WITH ASSISTED THERMAL SPECIES

摘要

The process includes the steps,in an integrated system,the injection of a melted PET resin into a moulded infusion cavity to form a preform (22),removal of the specimen (22) while the specimen (22) is at a temperature from 75 -C to 130 -C, the transfer of the specimen to a processing station with one the rate at which the surface temperature of the specimen (22) does not rise above 5 -C,the treatment of the propagation material by selective heating of specific areas of the propagation material (22) comprising at least the oil -forming zones; mu (51, 52),cylinder formation (53),fin formation (54),and the formation of a base (55) of the propagation (22) in order to obtain a temperature gradient in the specified areas of 20oC, the transport of the treated p plasma (22) at a mould casting station with a rate of inflation such that the surface temperature of the mould does not rise above 5 -C.
