- Inspection: Inspect the material to ensure no defects.

3. Lowering material

- Cutting: Cut the stainless steel sheet into blanks of required shape and size using laser cutting, plasma cutting or shearing machine.

4. Forming

- Stretching: The cut blanks are put into stretching molds and stretched and formed by stretching machine to form the basic shape of the cover.

- Trimming: Remove the excess material produced during the stretching process and trim the edges.

5. Finishing

- Punching: Punch out the air-permeable holes or pull-ring holes on the lid.

- Flanging: Flanging the edges of the lid to form the position of the sealing ring.

- Turning: Turn the inner and outer surfaces of the cover to ensure dimensional accuracy.

6. Surface treatment

- Polishing: Polishing the surface of the lid to improve the appearance quality and corrosion resistance.

- Cleaning: clean the lid to remove oil and impurities.

- Passivation: Passivate the stainless steel lid to enhance its corrosion resistance.

7. Assembly

- Seal Installation: Install the seal of silicone or other materials to the flap position of the lid.

- Functional Component Assembly: If required, install components such as pull ring, safety catch, etc.

8. Inspection

- Dimensional Inspection: Ensure that the dimensions of the lid meet the design requirements.

- Sealing test: Test whether the sealing performance of the lid is up to standard.

- Appearance Inspection: Check whether there are scratches, stains and other defects on the surface of the lid.
