Discover Durmapress’s Trusted Duct Machines!
Durmapress is more than just a bending machine expert. We are also a world-class duct equipment manufacturer, providing a full range of duct equipment for HVAC and industrial ventilation systems. When the Germany delegation visited our factory, they witnessed first-hand how our automatic duct production line, rectangular, spiral and round duct machines achieve “disruptive precision and durability”. Learn how Durmapress’s four core duct systems solve manufacturing challenges with unparalleled advantages. Our duct production lines are deeply trusted by international customers for their quality, performance and intelligent automation functions.


Full Range Of Duct Machine Equipment
Durmapress provides comprehensive solutions to meet the needs of modern HVAC duct manufacturing. Our duct equipment is mainly divided into four categories:
- Automatic duct production line
This is an automated production line designed for large-scale production. It integrates multiple processing steps, including uncoiling, leveling, crimping, slotting, punching, shearing and folding. The fully automated production line reduces manual labor, improves production efficiency, and ensures high consistency in rectangular duct manufacturing.
- Rectangular Duct Making Machines
These stand-alone machines are designed specifically for producing square and rectangular ducts. They include Pittsburgh Lock Forming Machines, TDF Flange Forming Machines, and Duct Seaming Machines. They are compact and easy to operate, making them ideal for small to medium-sized workshops.
- Spiral Duct Forming Machines
Spiral duct forming machines are designed specifically for making strong and airtight spiral ducts for commercial and industrial ventilation systems. The spiral forming process ensures structural integrity and reduces the need for internal reinforcement.
- Round Duct Making Machines
This type of forming machine is designed specifically for producing round ducts and accessories. It includes elbow machines, V-belt lock machines, flange forming machines, and sealing machines. These machines are essential for making precise and efficient round ducts.
Each duct machine is built with heavy-duty construction, precision control systems, and durable components to ensure you get a machine that will continue to operate reliably under demanding conditions.
