Reveal 9 Inspection Steps for Stainless Steel Water Bottle Manufacturers

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

In this step, it is necessary to check whether the inner container of the cup is clean and free of dirt after electrolysis.

6. Polish the outer surface of the cup

In this step, it is necessary to check whether the surface of the cup is polished smoothly.

7. Paint the outer surface of the cup

In this step, it is necessary to check whether the cup surface is painted with color difference, whether the paint thickness is uniform, whether there are impurities in the paint, and to test the fastness of the paint.

8. Print on the outside of the cup

In this step, it is necessary to check the color difference and fastness of the printing on the cup surface.

9. Pack the cup

In this step, the cup needs to be vacuumized again, and the appearance of all cups needs to be checked again. Only after the cups pass the inspection can they be packaged.
