METHOD OF MAKING PART FROM THERMOPLASTIC FILM BY DEEP DRAWING Russian patent published in 2013 - IPC B29C51/42 B29C51/46 B29C45/14 B29K69/00 

FIELD: process engineering.

SUBSTANCE: method of making the part from a film provided, at least partially, with printing, metalised and/or coated, includes the steps that follow. For this, flat film fragment provided, at least partially, with printing, metalised and/or coated, on one or both sides and made of, at least, one thermoplastic is used. Said fragment comprises, at least, one section that allows production of a part by deep drawing as far as size and printing, metallisation and/or coating are concerned. Said film fragment is placed at the frame so that only edges of film fragment are placed on said frame. Laid fragment is fed into heating zone for it to be heated to preset temperature. Heated fragment is quickly fed into deformation zone to be subjected to fluid pressurized to over 20 bar and isostatic forming to make required article in time smaller than 5 seconds. Note here that heating is carried out so that at least one film section or prevailing section has surface temperature exceeding Vick softening point B/50 by 10-65°C.

EFFECT: accurate arrangement of functional or decorative appearance.
