Cov txheej txheem pib nrog raw khoom npaj thiab zaj duab xis extrusion. Raws li cov khoom xav tau, cov yeeb yaj kiab thermoplastic xws li PVC, PET, OPS, lossis POF raug xaiv thiab tsim rau hauv cov khoom siv zaj duab xis los ntawm extrusion lossis casting txheej txheem. Tom qab ntawd, zaj duab xis undergoes stretching thiab tshav kub qhov chaw kom muaj ib tug so ntawm lub xeev ntawm chav tsev kub, kom ntseeg tau zoo tshav kub shrinkage zog rau tom ntej luam ntawv thiab txiav ua hauj lwm.
Tom ntej no los ntawm kev luam ntawv thiab qauv ua theem. Cov yeeb yaj kiab tau ua tiav tag nrho - xim luam ntawv, pleev xim UV txheej, kub stamping, lossis cov txheej txheem matte tiav los tsim cov qauv lag luam, barcodes, cov khoom lag luam, lossis cov ntsiab lus tshaj tawm. Tom qab luam ntawv, kom ntseeg tau tias cov nyhuv shrinkage thiab qauv kev ncaj ncees, txheej txheej los yog kev tiv thaiv zaj duab xis yog siv los txhim kho kev puas tsuaj, dej tsis kam, thiab tshuaj tiv thaiv corrosion.
Thaum kawg, slitting, tshuaj xyuas, thiab dov yog ua. Cov ntawv luam tawm yog txiav rau qhov dav thiab ntev ntev rau kev sau ntawv, ua cov yob lossis cov ntawv siv rau hauv cov kab ntim khoom siv. Kev tshuaj xyuas zoo kuj tau ua thaum lub sijhawm tsim khoom, suav nrog qhov tseeb qhov tseeb, kev ua haujlwm shrinkage, luam tawm meej, thiab adhesion. Lub tes tsho tsim nyog tau dov los yog ntim ua ntej tawm hauv lub Hoobkas thiab tuaj yeem siv ncaj qha rau kev ntim cov raj mis lossis lwm yam khoom ntim kom ua tiav cov txiaj ntsig zoo, zoo huv si, thiab ua kom zoo nkauj zoo nkauj.
