Accordingtotheproductionexperience,itisfoundthatthealuminum-plasticblisterpackagingmachineispronetoproblemsinblisterforming,hot-presssealing,etc.,andthefollowingbrieflydescribeshowtosolvetheseproblems.

1,blisterforming

Accordingtotheblisterformingmethod,thePVCfilm(hardpiece)isheatedandthenpassedthroughamoldandisformedintoablisterofadesiredshapeandsizebyusingcompressedairorvacuum.Therefore,whentheformedblisterhasaproblem,itisnecessarytoproceedfromthefollowingaspects.solve:

(1)WhetherthePVCfilm(hardpiece)isaqualifiedproduct;

(2)Whetherthetemperatureoftheheatingdeviceistoohighortoolow;

(3)WhetherthesurfaceoftheheatingdeviceadherestoPVC;

(4)Whethertheformingmoldisqualified,whethertheformingholeissmooth,andwhethertheairholeissmooth;

(5)Whetherthecoolingsystemoftheformingmoldisworkingproperlyandeffectively;
