What are the production steps of stainless steel thermos cups?

The stainless steel thermos cup is a high-end container that can keep drinks hot or cold for a long time. It is usually composed of stainless steel, plastic, silicone and other materials, and is produced through multiple processes.

First, cut the stainless steel sheet to the desired size. Next, a numerical control (CNC) bending machine is used to process the stainless steel plate and bend it into the shape of the cup shell and lid. Then, use an automatic welding machine to weld the cup shell and lid to ensure sealing performance. Additionally, polishing is required to give it a smoother appearance.

Next, the plastic parts are manufactured. First, the mold needs to be designed and manufactured. The plastic pellets are then heated and melted in an injection molding machine and injected through a mold. These plastic parts include handles, cup bases, and seals.

Finally, the pieces are assembled together. First, secure the plastic handle and cup base to the cup shell. Then, install the silicone sealing ring on the lid and turn the lid into place to connect with the cup shell to form a sealed space. Finally, through processes such as vacuum water injection and testing, product quality and performance are ensured. #Thermos cup
