stamping

 The stamping process is one of the methods to complete the plastic forming of metals, usually relying on presses and dies to apply external forces to plates, strips, tubes and profiles to produce plastic deformation or separation to obtain workpieces of the required shape and size, such as engine exhaust bends and muffler kits, manifold half shells, end cones, engine supports, stainless steel barrels, etc., all of which are formed by stamping technology is developing towards precision, versatility, energy efficiency The level and quality of the manufacturing process of pressed workpieces has a direct influence on the quality of automobile manufacturing to a large extent.
