Duct Bender: Fabricating Round and Rectangular Ducts

In the HVAC industry, the ability to accurately and efficiently bend ductwork is critical for creating components

that fit securely and perform optimally.

The Duct Bender range from Preda Machine encompasses various advanced machines designed

specifically for bending both round and rectangular ducts.

From 3 roller rolling benders and angle iron benders for round ducts to

manual, electric, hydraulic, pneumatic TDF folders,and pan brakes for rectangular duct forming,

our lineup covers all needs in duct fabrication.

Duct Benders for Round Ducts

The 3 Roller Rolling Bender is an exceptional machine designed for creating curves and bends in round ducts.

Utilizing a three-roller system, it allows for efficient control while bending, ensuring that operators can achieve the desired shape with precision.

The robust construction of the 3 roller rolling bender ensures stability and reliability,

making it suitable for high-volume production environments where consistency is key.

The Angle Iron Bender complements the rolling bender by specifically targeting the bending of angle iron,

which is often used in duct framing and reinforcement.

This machine provides fabricators with the ability to create precise angles and bends, allowing for true versatility in custom ductwork assemblies.

Duct Benders for Rectangular Ducts

For rectangular ducts, several types of TDF (Table Duct Flange) folding machines are employed,

each catering to different preferences and operational requirements:

Manual TDF Folder:

The Manual TDF Folder is designed for ease of use, allowing operators to create accurate TDF flanges through manual operation.

This compact machine is ideal for smaller fabrication shops or on-site applications where flexibility and portability are required.

Electric TDF Folder:

The Electric TDF Folder automates the bending process, enhancing speed and efficiency in duct forming.

Operators can easily set up the machine for precise bends, reducing manual labor while increasing production throughput.

Hydraulic TDF Folder:

The Hydraulic TDF Folder offers powerful bending capabilities while ensuring high precision.

The hydraulic system provides consistent pressure, allowing for accurate, repeated bends that meet stringent specifications.

Pneumatic TDF Folder:

The Pneumatic TDF Folder utilizes pneumatic power, offering a quick and efficient solution for forming TDF edges.

This machine is characterized by its reliability and minimal operator strain, making it suited for extended production runs.

American Type Pan Brake:

The American Type Pan Brake is a traditional yet essential tool for creating flanges and bends in rectangular ducts.

This machine provides fabricators with the ability to achieve precise angles and dimensions efficiently.

CNC Press Brake:

The CNC Press Brake takes automation to the next level.

With precise computer numerical control, it enables operators to execute complex bending patterns with high accuracy.

This machine is perfect for large production runs where consistency and precision are paramount.

Benefits of Using Duct Benders

Increased Production Efficiency:

Whether using 3 roller rolling benders for round ducts or more specialized TDF folders for rectangular ducts,

duct benders enhance workflow efficiency, allowing for faster production times and the ability to meet demanding deadlines.

Consistency and Quality:

Precision engineering ensures that each bend or fold produced is consistent in quality, reducing the risk of defects

and enhancing the overall performance of duct systems.

Flexibility for Various Applications:

The diverse range of machines enables fabricators to address various project specifications and material requirements,

ensuring that they can adapt to different customer needs.

Cost-Effectiveness:

By minimizing labor costs and material waste, duct benders represent a smart investment for manufacturers looking to improve their bottom line.
