Abstract

Sposób wytłaczania opakowań termoplastycznych z dodatkowym oznaczeniem w alfabecie Braille'a, charakteryzuje się tym, że folię PET poddaje się procesowi usuwania ładunków elektrostatycznych i mikrozanieczyszczeń od strony formy, za pomocą pasywnego neutralizatora z włosami z włókna węglowego, po czym wstępnie równomiernie podgrzewa się za pomocą gorącej tacki, następnie podgrzewa się do temperatury docelowej za pomocą strefy grzewczej w piecu, gdzie występuje dodatkowo strefa grzejna w miejscu wyciśnięcia oznaczenia alfabetu Braille'a, podgrzewa się do temperatury większej w stosunku do pozostałych stref, zaś po uzyskaniu wymaganej temperatury materiału poddaje się procesowi formowania ciśnieniem, po czym utrzymuje stałą temperaturę, następnie wytłacza się oznakowania alfabetu Braille'a, po czym chłodzi strumieniem powietrza, wentylatorem promieniowym wraz z wydmuchem, wydmuchuje się ukształtowany element oraz odcina nadmiar, następnie usuwa się ładunki elektrostatyczne nadmuchem z dejonizowanym powietrzem i pakuje w stosy.The method of extruding thermoplastic packaging with an additional marking in Braille is characterized by the fact that PET film is subjected to the process of removing electrostatic charges and micro-contamination from the mold side, using a passive neutralizer with carbon fiber hair, after which it is preheated evenly with hot tray, then heated to the target temperature by means of a heating zone in the furnace, where there is an additional heating zone in the place where the Braille alphabet is pressed, heated to a temperature higher than the other zones, and after obtaining the required temperature of the material is subjected to the process pressure molding, after which it maintains a constant temperature, then the Braille alphabet is extruded, then cooled with a stream of air, a radial fan along with the blow-out, the shaped element is blown and the excess is cut off, then s static electricity by blowing with deionized air and stacks.
