Cnc air duct production line is a duct making line with the highest automation and highest efficiency in rectangular air duct production line machines.

The spiral air duct forming machine is mainly used for making round spiral air duct. The machine can automatically complete round spiral tube with different diameters and different lengths based on customers demand. BLKMA company adopts the principle of using duct mold to form the spiral duct. Spiral duct machine is easy to operate and fast to form duct with accurate diameter.

The auto duct production line 2 machine can be used to feed material for HVAC duct manufacturer. Meanwhile, it can feed sheet metal for TDF flange.

A customer ordered the Auto duct line 3, CNC Plasma cutting machine, TDF Flange machine, Lock forming machine, and Duct folding machine, etc. BLKMA company completed the delivery in time after receiving the order.

Hydraulic duct lock seaming machine is used to lock 0.3-1.2 mm thickness rectangular HVAC air duct within 1500 mm length. The machine adopts PLC control and hydraulic drive.

Electric lock seaming machine can lock square HVAC air duct. The sheet thickness range is 0.3-1.2 millimeters. This machine is small and very easy to operate.

Lock forming machine is a necessary equipment for HVAC air duct manufacturing. Multi-function lock forming machine can form 6 shapes (7-function is available) to finish sheet jointing.

Hand folding machine is usually used to fold 1.5 mm thick sheet metal to finish HVAC air duct sheet plate three folds. The machine can bend TDF flange sheet metal and flat sheet.

The hydraulic folding machine is a sheet metal folding machine that makes rectangular HVAC duct. Actually, the hydraulic sheet metal folding machine can be divided into two types, hydraulic TDF flange sheet folding machine and hydraulic flat sheet folding machine.

Line 5 beading machine and line 7 beading machine are used to make sheet metal reinforced ribs during HVAC air duct processing.

Portable angle steel flange production line is mainly for punching and cutting duct angle steel flange(30-50 angle steel). Cutter and punching die are both made of Japan SKH51, which are fast and accurate.

CNC plasma cutting machine is mainly for automatically lofting and cutting the deformed workpiece. You can select a drawing from the new version of CAM-DUCT and input dimensions and choose a way of connection, then the software will start calculating

Air booster fans are an essential tool for improving air circulation in a room or space. These fans help to increase airflow, improve ventilation, and ensure that air is distributed evenly throughout the room. In this ultimate guide, we will explore the benefits of using an air booster fan and 4-inch duct booster, discuss their energy efficiency, provide tips on improving air circulation, and guide you on how to determine the right size and capacity of an air booster fan for your space.

The pneumatic folding machine adopts the 4-cylinder pneumatic system as the power source. Two cylinders are used for bending when the other two are used for pressing.

J23 series presses are one of the new generations of plate process and developed by BLKMA team. The press is for cutting, punching
