Have you ever used a pressure cooker? How is the pressure cooker made? Pressure cooker, also called pressure cooker, is a common cooker in our life. Making a pressure cooker starts with this stainless steel disc.

Firstly, the pressure cooker body is molded. First, put the disc soaked with lubricant on this plastic molding machine. The machine will process the disc into the shape of a pot, and then use this punch to press a groove on the edge of the pot. The groove will be embedded with the lid of the pressure cooker. Then, wrap the aluminum plate with a layer of aluminum-silicon-copper mixture, and then put it at the bottom of the pot with a stainless steel plate on it. Subsequently, the turntable will send the pot body into the heating furnace, melt the aluminum and silicon-copper solution at a high temperature of 600 degrees Celsius, so that the disk surface and the pot bottom are completely fused together, and then put the pot bottom into cold water to cool.

Second, polish the pressure cooker. Next, use a cutting machine to eliminate the serrated edge formed after the bottom of the pot is fused and make it into a smooth inclined plane. Then put the pot into this processing bin for grinding and polishing, and the polished pot will be sent to the water washing station by conveyor belt to wash away the polishing residue. Then the stainless steel plate is made into the pot cover of the pressure cooker through six pressing processes, and the hole in the middle of the pot cover is two safe gas methods for installing the pressure cooker.

Third, install safety devices. In order to install the safety valve, the worker should align the fixing ring with the larger hole on the cover, then put the spring valve into the hole, and the automatic device below will tighten the spring valve. This smaller hole will be equipped with a spare air valve to release excess steam from the pressure cooker to prevent explosion. After the rubber sealing ring is put on the pot cover, the pot cover of the pressure cooker is completed. Then weld a few bolts on both sides of the pot body, install the bracket, screw on the bolts, tighten the handle, and finally label the pressure cooker. Finally, it is packed and packed, and then it can be transported to the sales market. At this point, the production process of the pressure cooker has been completed.
