When we buy the mould, we can save part of the cost. This is to consider the problem of matching the rectangular tube or square pipe mold with other size moulds. The main problem is matching with the round tube mould, because the rectangular tube or square tube is obtained from the shape transformation of the round tube.

Let me give you an example to illustrate that if we produce 30 * 10 rectangular tubes and convert them into round tubes, it will be 25.4, so we only need to replace the straightening head and the front and rear two groups of pipe molds, and then we can use them directly. Is it possible to save a lot? Most of them are still 25.4 molds, and the straightening head and the front and rear two groups of molds are replaced with 30 * 10 pipe making molds, No extra cost.

The key point of the matching use and exchange between the pipe molds is to consider whether the open band width is consistent. As long as the open band width is the same, almost only part of the dies need to be replaced.

Key words:pipe mold
