制造兩片罐的兩種成型方法均采用金屬板成型法。這種方法是以在復合應力作用下，通過晶體結構重新排列而表現出的金屬“流動性”為基礎，而且在這一過程中材料不應發生斷裂。就要用勁諾沖壓拉伸潤滑油，對鋁罐體進行沖壓和拉伸。

沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)鋁罐沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)壓成型。即利用沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)壓機(ji)的(de)一(yi)個沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)頭(tou)將一(yi)塊平板沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)進圓(yuan)柱形的(de)沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)模中，從而使(shi)平板變形而成圓(yuan)筒。在(zai)初(chu)始沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)壓后形成的(de)杯的(de)直(zhi)徑，可以應用再沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)壓工序來縮(suo)小。再沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)壓工序用一(yi)沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)壓套筒代替沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)模，安裝在(zai)沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)頭(tou)與(yu)沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)杯內(nei)(nei)徑之(zhi)間。等面積規(gui)則決定了伴隨直(zhi)徑縮(suo)小的(de)是高度的(de)增加，再沖(chong)(chong)(chong)(chong)(chong)(chong)(chong)壓工序可再重復一(yi)次，書直(zhi)徑在(zai)一(yi)定的(de)極限(xian)范圍內(nei)(nei)逐漸縮(suo)小，并避(bi)免金屬發(fa)生(sheng)斷裂(lie)。

勁諾鋁罐沖壓拉伸油低粘度快干型揮發性沖壓油。本產品是由精制基礎油配合特殊復合添加劑調配而成。具有優異的潤滑、冷卻性，而且揮發快、殘留少、氣味小。適用于銅片、鋁片、矽鋼片及鍍鋅片使用，已廣泛應用于空調、電器、熱轉換器及空氣干燥機等工業。
