Laser Cutting Thickness Chart
Understand actual cutting ranges for HVAC duct sheet thicknesses, and how to match laser power to 0.5-2mm galvanized and stainless steel.
HVAC Duct Manufacturing CNC Machines
Efficient sheet metal cutting and forming for HVAC ducts, ventilation components, pipe fittings, and ductwork. Efficient processing for ventilation and air handling equipment.
Industry Overview
What is this application about?
HVAC duct manufacturing involves duct sections, pipe fittings, flanges, and ventilation components. Sheet metal processing is used to cut sheets to size, notch, and form bends for duct assembly. Materials typically use galvanized or stainless steel sheets in the 0.5-2mm range. Production can be batch or higher volume; CNC bending and cutting provide consistent dimensions for duct and pipe fitting parts and support efficient processing.
Different duct sizes and fitting types require different part dimensions and bending configurations. CNC press brakes and fiber laser cutting machines support flexible HVAC duct production.
Fabrication Requirements
Common Processing Requirements
Bending Duct Sections and Flanges
Duct sections, pipe fittings, and flanges require consistent bending angles for proper assembly and sealing.
Cutting and Notching Sheets for Assembly
Fiber laser cutting precisely cuts and notches sheets for duct assembly without secondary processing.
Repeatable Dimensions for Duct Fit
Consistent part dimensions ensure ducts and fittings fit correctly during installation.
Efficient Production for Batch Orders
Batch duct production benefits from stable CNC processes that maintain quality in repeat orders.
Core Machines
Recommended Machines
CNC press brakes are used to bend duct sections, pipe fittings, and flanges at repeatable angles. Fiber laser cutting machines cut and notch duct and pipe fitting sheets. Shearing machines are suitable for straight-line cutting when laser is not needed. Equipment selection is matched to sheet size, thickness, and volume.

HVAC duct processing includes rectangular and round ducts, pipe fittings, and custom ventilation components. Machine combinations depend on duct size, material thickness, and volume.
Standard Rectangular Duct Production
Most CommonBest for: HVAC duct manufacturers and sheet metal fabrication workshops producing rectangular ducts, pipe fittings, and standard ventilation components.
Fiber Laser + CNC Press Brake + Shearing
Fiber laser handles duct blanks, notches, and fitting cutouts. Press brake forms flanges and fittings. Shearing efficiently prepares straight blanks for rectangular ducts.
Custom and Complex Duct Processing
FlexibleBest for: Processors producing custom duct shapes, complex fittings, and non-standard ventilation components for specialized projects.
Fiber Laser + CNC Press Brake
Fiber laser handles complex contours and fitting shapes. Press brake covers custom bends and flanges. Practical combination for flexible low-volume custom work.
For 0.5-2mm galvanized or stainless steel HVAC ducts, practical fiber laser and press brake combinations handle most rectangular and fitting duct requirements.

FAQ
Frequently Asked Questions
HVAC duct and ventilation production typically uses CNC press brakes to bend duct sections, pipe fittings, and flanges, fiber laser cutting or shearing to cut sheets to size. Galvanized and stainless steel sheets are common; thickness is typically 0.5mm to 2mm. Laser cutting handles contours and notches; press brake forms bends for duct sections and connection flanges.
Yes. Fiber laser cutting is widely used for duct blanks, fittings, and connectors. It precisely cuts thin to medium gauge sheets and handles notches and patterns needed for duct assembly. Table size and power selection matches sheet dimensions and thickness. Shearing is also used where only straight-line cutting is needed.
Consider maximum sheet length (duct and fitting sizes), material thickness (typically 0.5-2mm), and bending complexity. Tonnage and bed length should match your largest parts. CNC control supports repeatable bending of duct sections and flanges. We can recommend press brake configurations based on your parts mix and volume.
Duct and fitting sheets are typically 0.5-1.5mm for standard ducts, 1-2mm for heavier sections or fittings. Standard ranges of CNC press brakes and fiber laser cutting machines cover these thicknesses; exact capabilities depend on machine specifications.
