At present, as for the traditional labor production line, although the investment in the initial stage of construction is relatively small, but with the expansion of market demand and the rising of labor costs, its inherent inefficiency and poor product quality stability are increasingly affecting the development of enterprises. Automated production lines just happen to solve these problems. Higher production efficiency, stable product quality and lower single-piece production costs under scale production conditions are the advantages of automated stamping lines, especially for the production of large body panels. In short, automated production is the trend of the times! 1. delivery method (Progressive) The more common one. It is mostly used in electronic, digital, OA, home appliances and other products, with high production efficiency, general precision effect and low material utilization. Combined with the servo machine, it can meet the requirements of production efficiency and high precision. 2. multi-station handling method (Transfer) It is more common in the processing of automotive interior parts, and the products with higher added value have higher material utilization rate and better forming effect. But speed (SPM) is difficult to reach more than 30. With the 3D servo multi-station handling system, it can reach SPM60 or above, but rarely have professional manufacturers that can do it. 3. robotic method (Robot) It is more common in products with high added value and high requirements on appearance, such as IPAD casing. A variety of combinations are more suitable for future higher product requirements, and Robot will abandon traditional processing methods in the next few years. 4. tandem mode (Tandem) It is more common in the production line of large body parts for automobiles. At present, several major automobile manufacturers in the market are using this processing method.
