First of all, the factory will process the purchased stainless steel sheet or stainless steel coil into tubes of different diameters through stretching or tube drawing processes, and these tubes will be cut into tubes of appropriate size according to the requirements of the inner tank of the water cup . The production department will process these tubes in different time periods according to the diameter, size and thickness of these tubes.
Immediately afterwards, the production workshop first began to shape these pipe materials. The commonly used design is a water expansion machine and a shaping machine. Through this process, the water cup can meet the shape requirements. The molded tubes will be classified according to the outer shell and inner tank of the water cup, and then enter the next process.
The reshaped pipe material after being put on the machine again will be welded at the mouth of the cup first, but in order to ensure the welding quality, the mouth of the cup must be cut first to ensure that the mouth of the cup is smooth and of the same height. The semi-finished product with welded cup mouth must be ultrasonically cleaned before entering the next process. After ultrasonic cleaning, the bottom of the cup must be cut before welding. The effect is the same as the cutting before welding the cup mouth. The stainless steel water cup is divided into inner and outer layers. Therefore, two cup bottoms are usually welded, and some water cups also weld three cup bottoms according to structural requirements. #insulated mug
The semi-finished product that has been welded is ultrasonically cleaned again. After cleaning, it enters the electrolysis or polishing process. After completion, it enters the vacuuming process. After the vacuuming process is completed, the production of a thermos cup basically completes half of the process. Next, it needs to be polished, sprayed, printed, assembled, packaged, etc. At this time, a thermos cup is born. Everyone will think that these processes are very fast. In fact, each process requires not only exquisite skills, but also reasonable production time. In this process, there will be defective products that are not qualified in each process.
