燙(tang)金(jin)基本工藝是在壓力(li)狀(zhuang)態，即電(dian)化(hua)(hua)鋁被燙(tang)印(yin)版、承印(yin)物壓住的(de)(de)狀(zhuang)態下，電(dian)化(hua)(hua)鋁受熱使其上熱熔(rong)(rong)(rong)性(xing)(xing)(xing)的(de)(de)有機硅樹(shu)脂層和膠(jiao)牯劑(ji)熔(rong)(rong)(rong)化(hua)(hua)，此時受熱熔(rong)(rong)(rong)化(hua)(hua)的(de)(de)有機硅樹(shu)脂粘性(xing)(xing)(xing)變小，而特種熱敏膠(jiao)粘劑(ji)受熱熔(rong)(rong)(rong)化(hua)(hua)后粘性(xing)(xing)(xing)增加，使得鋁層與電(dian)化(hua)(hua)鋁基膜剝(bo)離的(de)(de)同(tong)時轉(zhuan)印(yin)到了承印(yin)物上。隨著壓力(li)的(de)(de)卸除，膠(jiao)粘劑(ji)迅速冷卻固化(hua)(hua)，鋁層牢固地附(fu)著在承印(yin)物上，完(wan)成一個燙(tang)印(yin)過程。
