一、生产流程二片冲拔铝或马口铁罐的生产流程为:杯成型→冲拔→整修→清洗→与印刷底漆→干燥→内部涂料→干燥→上口轧颈状凹槽→装盖→测试→出厂。将卷材或片材送入垂直式坯件冲压机,冲成4～10个杯坯。杯坯输送到卧式挤拉机,将罐壁拉成需要的厚度。罐壳退出,经过整修和清洗,去掉润滑油,外部涂底漆,加四色印刷,干燥。内部喷涂一或二次,根据内容物而定,进行第二次干燥。装上易开盖。最后一步是通过灌入空气测漏。
First, the production process Two punching aluminum or tin cans of the production process: Cup forming → Chong pull → renovation → cleaning → and printing primer → drying → internal coating → drying → roll-neck roll groove → loading → Test → factory. The web or sheet into the vertical blank stamping machine, washed into 4 to 10 cup blank. The cup is conveyed to a horizontal puller, which pulls the can wall to the desired thickness. Shell exiting, after renovation and cleaning, remove the lubricant, external primer, plus four-color printing, drying. Internal spray one or two times, depending on the content, the second drying.
