Round Duct Machine in Duct System

Durmapress recently welcomed a delegation from Mongolia, marking their first visit as a new client specializing in construction and HVAC equipment. Their visit focused on evaluating our metalworking machinery, including the metal shearing machine, angle iron roller, 3-inch duct production line, press brake, and fiber laser cutting machine.

Client Background & Objectives

The Mongolian client, a key supplier of 3-inch ducts and structural components for infrastructure projects, sought equipment to enhance production efficiency. Their goals included:

– Testing metal shearing machines for cutting thick steel plates.

– Evaluating angle iron rollers for shaping 3-inch duct supports.

– Verifying fiber laser cutting machines for precision sheet metal processing.

Factory Tour Highlights

In addition, the customer showed great interest in our angle iron roller, which is perfect for forming angle irons used in construction and industrial applications. We demonstrated how it smoothly bends various metal profiles with minimal deformation.

The customer also reviewed our capabilities in fabricating 3 inch ducts, which are commonly used in HVAC systems. Our machines ensure high precision and airtight seams, which are essential in ductwork production.

Of particular note was the demonstration of our high-precision press brake, which features multi-axis control and user-friendly programming. This machine is capable of handling complex bending tasks with repeatable accuracy.

Finally, our Fiber Laser Cutting Machine was presented in action, cutting through stainless steel and carbon steel sheets with clean edges and high speed. The customer was impressed with its performance and ease of operation.

– Verifying fiber laser cutting machines for precision sheet metal processing.

The air duct system is the most important part of air conditioning and ventilation engineering. Its main function is to transfer the regulated air to the terminal equipment as efficiently as possible according to the design flow. Generally, there are three shapes of duct cross section: rectangular, circular and oblate. Rectangular air duct is usually made by riveting four steel plates. The circular air duct is made of 137 mm wide steel plate on the circular air duct machine. Flat circular ducts are rare. It is generally formed by extruding the round duct through the round duct machine. Before 1960, because of the simple manufacturing process and the small installation space, most of the ventilation systems used rectangular ducts. With the successful development of large-scale spiral circular air duct machine, a large number of engineering examples have proved that circular air duct is far better than rectangular air duct in economy or other engineering parameters.

At present, the widely used fabric air duct in the market is an air distribution system which integrates the functions of tuyere, air supply pipe, static pressure box, thermal insulation material, air valve, etc. It has the advantages of accurate and even air supply, light weight installation block, high aesthetics, anti-bacterial and anti mildew, etc., which are recognized by users and widely used. The shape of the air duct made of fiber fabric has circle, semicircle, 1 / 4 circle, ellipse and semi ellipse to meet the needs of different building structures.
