燙(tang)金(jin)基本工藝是在壓力(li)狀態(tai)，即電(dian)(dian)化(hua)(hua)鋁(lv)被燙(tang)印(yin)(yin)版、承印(yin)(yin)物(wu)壓住的狀態(tai)下，電(dian)(dian)化(hua)(hua)鋁(lv)受熱使其上(shang)(shang)熱熔(rong)(rong)性的有(you)機(ji)硅(gui)樹(shu)脂層(ceng)和膠牯劑熔(rong)(rong)化(hua)(hua)，此時受熱熔(rong)(rong)化(hua)(hua)的有(you)機(ji)硅(gui)樹(shu)脂粘性變小，而(er)特(te)種(zhong)熱敏膠粘劑受熱熔(rong)(rong)化(hua)(hua)后(hou)粘性增加，使得鋁(lv)層(ceng)與(yu)電(dian)(dian)化(hua)(hua)鋁(lv)基膜剝(bo)離的同時轉印(yin)(yin)到了承印(yin)(yin)物(wu)上(shang)(shang)。隨著壓力(li)的卸除，膠粘劑迅速(su)冷(leng)卻固化(hua)(hua)，鋁(lv)層(ceng)牢固地附著在承印(yin)(yin)物(wu)上(shang)(shang)，完成(cheng)一個(ge)燙(tang)印(yin)(yin)過程。
