零(ling)件(jian)(jian)(jian)金屬板(ban)材加(jia)(jia)工(gong)就叫鈑金加(jia)(jia)工(gong)。具體譬如(ru)利用板(ban)材制作煙囪、鐵桶、油箱油壺、通風管道、彎(wan)(wan)頭(tou)大小(xiao)頭(tou)、天圓地方、漏(lou)斗(dou)形(xing)等(deng)，主(zhu)要(yao)(yao)工(gong)序有(you)剪切、折彎(wan)(wan)扣邊、彎(wan)(wan)曲(qu)成型、焊(han)接(jie)、鉚接(jie)等(deng)，需要(yao)(yao)一定(ding)幾何知(zhi)識(shi)。鈑金件(jian)(jian)(jian)就是(shi)薄板(ban)五金件(jian)(jian)(jian)，也就是(shi)可以(yi)通過沖壓(ya)，彎(wan)(wan)曲(qu)，拉伸(shen)等(deng)手段(duan)來加(jia)(jia)工(gong)的零(ling)件(jian)(jian)(jian)，一個大體的定(ding)義就是(shi)在加(jia)(jia)工(gong)過程中厚度不變的零(ling)件(jian)(jian)(jian)。相對應的是(shi)鑄造件(jian)(jian)(jian)，鍛(duan)壓(ya)件(jian)(jian)(jian)，機械加(jia)(jia)工(gong)零(ling)件(jian)(jian)(jian)等(deng)。
