Compared with the traditional stamping and welding process, copper pipe fittings within the main advantages of high-pressure forming is: reduce the weight although, saving materials: reduce the number of parts and molds, reduce mold costs; reduce the amount of subsequent machining and assembly welding; reduce production costs, although the high-pressure molding technology has many advantages, but because of its expensive investment in equipment, especially in our country, high-pressure molding technology, research and application of the late start. There is also a lack of systematic knowledge of process design and equipment design.
Inside the high molding parts in the automobile application parts are: automobile air conditioning copper piping; chassis parts, including subframe, rear axle, longitudinal beams and bumpers, etc.; body components, including the dashboard support beam, radiator support, seat frame, upper side beams and roof beams, etc.; engine and drive system, including manifolds and exhaust parts, camshafts and driveshafts, etc.; steering and suspension systems, including the control arms and steering rods, etc.
Structure of automobile exhaust system: it is composed of ① exhaust manifold, ② front pipe, ③ flex pipe, © converter, ⑤ center pipe, ⑥ silencer, © tailpipe, and the automobile exhaust system is mainly connected by pipe fittings.
