Stainless steel water bottle manufacturers need to conduct all-round inspections on the water bottles wholesaled by customers, so as to ensure the quality of the products, but the inspection steps of each manufacturer are not exactly the same. Today Oranda will introduce at least 9 stainless steel water bottle inspections steps.

1. Cut the tube into the required length for making cups.

In this step, it is necessary to check whether the pipe material is flat and whether the material is 201 stainless steel or 304 stainless steel.

2. Use the machine to expand the stainless steel pipe into the shape of a cup

This step needs to check whether the cup shape is smooth and flat.

3. Connect the inner and outer layers of the cup by electric welding

In this step, it is necessary to check whether the cup welding is smooth and whether the scar at the welding point is cleaned.

4. Vacuum the cup

In this step, it is necessary to check whether the cup is insulated, and the following thermometric machines are required for this check.

5. Electrolyze the inner tank of the cup
