There are many kinds of exhaust pipes, some have many exhaust holes, some have a certain shape. I believe many people are interested in knowing about the technological process of the automobile exhaust pipes in the production of these pipe making machine. Here I will tell you about it.

The automobile exhaust pipes with many holes are first punched out of the holes by a punch press, and then the steel coil with holes is put on the pipe making machine production line for production. This operation is a relatively simple one, which is applicable to the hole symmetry requirements are not high exhaust pipe.

Another kind of automobile exhaust pipe with shape requirements is produced by using high frequency pipe welding machine. This kind of automobile pipe first uses high frequency pipe welding machine to produce pipes of specified shape, and then according to the shape of automobile exhaust pipe, the produced pipes are reprocessed. This may involve the use of water expansion technology, but it may also involve stamping technology, resulting in a composite shape require for a automotive exhaust pipe. Some car tail pipes and some motorcycle exhaust pipes are produced in this way.

Here,do you know a lot about the technological process of the automobile exhaust pipe making machine?
