Metal stamping
Metal stamping is really a manufacturing process where a metal stamping die or a series of metal stamping dies are utilized to form sheet metal into three-dimensional dimensional shaped workpieces. It's utilized in a variety of industries, for example: automotive and household appliances. Automotive stampings are a fundamental part of the metal stamping industry. This kind of processing enables extremely powerful forming of sheet metal. The metal stamping dies are installed on a press, which forms one workpiece per stroke.
Features
(1) The dimensional accuracy of the stamped part is guaranteed through the die, that has the characteristic of being one mould, therefore the quality is stable and interchangeable. The die guarantees the dimensional and shape accuracy from the stamped part and does not generally damage the surface excellence of the stamped part, as the life of the die is generally long.
(2) Because of the utilization of mould processing, it is possible to obtain parts with thin walls, lightweight, good rigidity, high surface quality and sophisticated shapes that cannot be manufactured by other processing methods or are difficult to fabricate. Stamping can establish parts having a a lot of different sizes and sophisticated shapes, such as stopwatches for clocks and watches, longitudinal beams and coverings for cars, etc. Together with the cold deformation and hardening effect of the material during stamping, the force and rigidity of stamping are higher.
(3) The stamping process generally does not require heating from the blank, nor will it cut a lot of metal like the cutting process, so it doesn't only save energy but additionally saves metal, as the stamping generally does not generate chips and scraps, the consumption of materials are less, with no other heating equipment is required, so it is a material-saving and energy-saving processing method, and also the cost of stamping parts is lower.
(4) For ordinary presses, a large number of pieces can be achieved each minute, while high-speed presses can establish hundreds or thousands of pieces per minute. The development efficiency of stamping processing is high, and the operation is convenient and simple to realize mechanization and automation. It is because stamping is dependent on the punching die and stamping equipment to complete the procedure, the number of strokes for ordinary presses can reach dozens of times per minute, high-speed presses can reach hundreds of times each minute or even more than a thousand times, and every stamping stroke may get a punching part.
