Production process:
1. Loading and leveling--cutting and unloading
2. Automatic rolling and welding--flanging and rolling--rib expansion----closed barrel roller compression neck---open barrel roller compression neck----capping machine--reverse barrel inversion----bottom sealing----leakage test (sampling);
3. Stamping bottom cover----stamping large and small threads-----pre-rolling glue dripping
4. External spraying of barrel body + baking + secondary spraying + baking;
5. Internal spraying and capping-external spraying of barrel body + baking
