SAIC Volkswagen Langfang engine turbine rust screw corrosion
Usually, the frequency of the car is relatively low, and it is less than 6,000 kilometers in a year. However, the turbine and its attached screws of the thousands of kilometers of the car are very corroded. The screw is rusted and cannot be unscrewed. It is suspected that the turbine and screw materials are poor. , does not meet the requirements of high temperature components, I hope manufacturers pay attention!
We have over 20 years of custom making Stamping Metal Steel Products. Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene.
Stamped parts were used for mass-produced bicycles in the 1880s. Stamping replaced die forging and machining, resulting in greatly reduced cost. Although not as strong as die forged parts, they were of good enough quality.
