FAQs of HVAC Duct Machines

Q. For square duct production, how to decide whether to choose auto duct line or small machine combination?

A. This depends on the customer's production volume and budget. If the customer needs mass production and has a sufficient budget, then we recommend auto duct line. Compared with the combination of small machines, the auto duct line is an efficient and economical production method. It not only reduces the use of manual labor, but also greatly improves production efficiency. For customers with small batch production, it is more economical to choose a small machine combination.

Q. Where do you mainly sell air duct machines?

A. Our air duct machine for sale are sold all over the world, and are particularly popular in South America, the Middle East, and European markets.

Q. How long is your machine's service life and how long is the technology update period?

A. Our machines can generally be used for more than ten years. However, we recommend that customers update the machine within five years, so as to maximize production efficiency and product excellence rate. Regarding technological updates, various technologies are becoming mature, and it will take at least several decades to have new breakthroughs.

Q. What is the technological level of your spiral duct machines in China and the world?

A. Our spiral duct machine is the best product in China, and its technology is far ahead of other manufacturers. Even on a global scale, our machines are at the top level.

Q. Regarding aluminum flexible duct forming machine, is it better to choose solid glue or liquid glue?

A. Under the premise of meeting the budget, we recommend using liquid glue. Because the liquid glue solidifies faster, and the machine matched with the liquid glue has functions such as automatic cutting and shrinking, the production efficiency is also higher.
