D28 M11 H15 Double Layer Laser Cutting Nozzle for Han's Compatible Fiber Laser Cutting Head

D28 M11 H15 Double Layer Laser Cutting Nozzle

The D28-E-C-15 double layer laser cutting nozzle is designed for use with compatible Han's fiber laser cutting heads and CNC fiber laser cutting machines.

Featuring a 28 mm outer diameter, M11 threaded connection and 15 mm overall height, the nozzle provides a precise mechanical interface with the cutting head and supports controlled assist-gas delivery during fiber laser cutting.

The double layer construction is suitable for cutting applications where stable gas flow, nozzle concentricity and consistent cutting performance are important. Precision machining of the nozzle aperture and internal gas passage helps maintain proper gas distribution around the laser cutting zone.

This nozzle series is available in a wide range of apertures from Ø1.2 mm to Ø6.0 mm, allowing users to select the appropriate specification according to laser power, material type, sheet thickness, assist gas and actual cutting parameters.

The D28-E-C-15 nozzle can be supplied as a replacement laser consumable for compatible Han's cutting head configurations used in industrial sheet metal processing.

Technical Specifications

Available Nozzle Aperture Sizes

Selection Note: The correct nozzle aperture should be selected according to laser power, material type, sheet thickness, assist gas, cutting head configuration and actual cutting parameters.

Typical Applications

The D28 M11 H15 Han's compatible double layer laser nozzle is suitable for fiber laser cutting systems used in industrial sheet metal fabrication.

Typical applications include:

• Stainless steel laser cutting
• Carbon steel laser cutting
• Mild steel sheet cutting
• Galvanized steel cutting
• Aluminum sheet processing
• CNC fiber laser cutting
• Sheet metal fabrication
• Industrial laser cutting applications

Depending on the laser cutting system and process requirements, different nozzle apertures may be selected for cutting with oxygen, nitrogen or compressed air as the assist gas.

How to Select the Correct Laser Nozzle

Choosing the correct laser nozzle requires matching both the cutting head interface and the actual processing conditions.

Cutting Head Compatibility
Confirm that the cutting head uses the corresponding D28 outer diameter, M11 thread and H15 nozzle geometry.

Nozzle Aperture
Select the appropriate aperture according to material type, sheet thickness and cutting process.

Laser Power
Different laser power levels may require different nozzle aperture and gas-flow configurations.

Material and Thickness
Carbon steel, stainless steel, aluminum and other materials may require different cutting parameters.

Assist Gas
Oxygen, nitrogen and compressed air have different pressure and flow characteristics.

Cutting Parameters
Laser power, focal position, cutting speed and gas pressure should be considered together when selecting the nozzle.

If the exact nozzle specification is unknown, the existing nozzle model, dimensions, markings, product photos or cutting head model can be used for identification.
