Technology of reducing material loss in air duct manufacturing

During the production of air duct, due to the specification difference between the air duct plate and the specification difference in the duct design, the loss of the panel is caused (the loss is only 2.8 square meters of the difference in the number of a piece of air duct plate if it is 3 square meters). So how to reduce the loss of plate? Now I would like to suggest a few methods for your reference;

1. Before making the air duct, it is necessary to carefully understand the structure and specification of the air duct on the drawing, so as to cause unnecessary waste when cutting plates, which is also the most critical step to reduce the loss.

2. Clean up the foreign air duct and make it centralized and unified. Try to make the opposite type pipe first. In this way, all the large-scale plates left in the production of the opposite air duct can be applied to the straight pipe behind.

3. In order to reduce the complexity of some layout in the duct design, it can reduce the unnecessary waste of materials and the trend of complexity (of course, this should be approved by the owner).

4. The leftover material generated in the process of plate cutting should be applied to the upper part of the air duct as much as possible. Because the upper surface is hidden, it can be used as long as it does not affect the air duct itself (the sealing must be done when splicing to avoid air leakage of the air duct).

5. When connecting the air duct, the distance should be as large as possible, especially the small branch pipe can be processed according to the length of the plate, which can save the waste of auxiliary materials of air duct, and also can speed up the progress of air duct manufacturing.

The overall production of the air duct should be based on the actual situation of the site and the requirements of the drawings. It is important to remember that the quality of the air duct should not be ignored in order to leave some links that should not be omitted.
