不銹鋼封頭廠家價格低質量好，旋壓普通采納冷成形。因為沖壓是要模具的，小的封頭根基上都是榻佳的模型，只有說DN幾許的就能壓了。沖壓又分冷沖壓和熱沖壓.碳鋼多選熱沖，不銹鋼多選冷沖。薄的也多選冷沖，厚的多選熱沖.如果大封頭的話多淘定壓，了日旱旋壓壞處即是封頭的R段處所成型欠好。沖壓有鐵模因此制品尺寸是不變的適用大批生產外貌較毛糙;旋壓沒有大鐵模尺寸者做適用小量生裝備封頭產外貌滑膩沖壓可分為冷中壓和繃中壓，冷沖壓用于規格小的，厚度較的接納熱沖壓。沖任連寸頭每每發現的壞處要緊有拉薄、褶皺橢圓旋壓封頭的范例、規格、材質，可接納整板或拼板經冷鐵封頭沖壓、熱沖壓、冷旋壓、熱旋壓、冷卷、熱卷等技巧成形；也可分瓣成形后再組焊成封頭。橢圓封頭加熱爐的爐內空氣應呈中性或弱氧化性。且應不小于3倍封頭外貌壁厚。
