HALANSM® Supersonic Laser Nozzle OD28 x H15 x M11, Single Layer, Copper

Aftermarket supersonic laser cutting nozzle, 28mm OD x 15mm height x M11 thread, for Han's / DNE / Hongshan high-power fiber laser cutting heads.

HALANSM® HLN-SUP-D28H15M11 is an aftermarket supersonic laser nozzle sized OD 28mm x H 15mm x thread M11, built for Han's, DNE and Hongshan high-power fiber laser cutting heads to deliver stable gas focusing and clean, dross-free cuts.

Product Overview

The supersonic nozzle sits at the very bottom of the laser cutting head, directly below the focus lens and ceramic ring, where it shapes and accelerates the assist gas around the focal point. Its bell-shaped (trumpet) bore is engineered to reach supersonic gas velocity, so the molten material is ejected cleanly and the kerf stays sharp even at high feed rates.

HLN-SUP-D28H15M11 is a single-layer, natural-color copper construction with a built-in internal step that improves gas-jet stability. It is an aftermarket replacement part and is not an original OEM component.

Key Advantages

Supersonic Gas Focus

The converging-diverging bore profile accelerates assist gas to supersonic speed, keeping the molten slag clear of the kerf and reducing dross on the underside of the sheet.

Internal Step for Stability

A precision-machined internal step (raised seat) centers the gas flow and protects the bore from back-splatter, helping the nozzle hold its profile through long production runs.

High-Purity Copper Body

Forged from high-purity copper for excellent heat dissipation, then CNC-finished for concentricity between the M11 thread, the bore and the mounting face.

Crash-Resistant Bell Profile

The wide umbrella (bell) shape gives the nozzle standoff clearance and deflects spatter away from the cutting head, reducing the chance of a head crash during high-speed profiling.

Specifications

Selection Guide: Caliber by Material and Thickness

Confirm the exact orifice and thread pitch with your cutting-head model and original part number before ordering. The guide above is a starting point, not a substitute for machine-specific settings.

Compatible Equipment

HLN-SUP-D28H15M11 is an aftermarket replacement for cutting heads that use a 28mm OD x 15mm height x M11 nozzle. It is commonly paired with the following brands and series:

- Han's Laser fiber cutting heads, including DNE-series platforms

- Hongshan / HSG high-power cutting heads (D28 family)

- Other M11, D28 x H15 cutting heads of compatible interface

Brand names above are used only for fitment identification. HALANSM® is not affiliated with, nor does it claim authorization from, the original manufacturers. Provide your head model and original part number for a fitment check.

D28 Nozzle Family: Watch the Thread, Not Just the Diameter

All four share the same D28 (or D32) outer diameter and 15mm height, but the thread is different. Matching the thread is the only way to avoid cross-threading or a loose seat, so always confirm the head interface before ordering.

Installation and Handling

1. Power down the laser and lock out the cutting head before any service work.

2. Remove the worn nozzle by turning it counter-clockwise; support the head so no side load reaches the ceramic ring.

3. Clean the mounting face and thread with a lint-free cloth; check the O-ring and ceramic ring for cracks or slag buildup.

4. Start the new nozzle by hand to ensure the M11 thread engages cleanly, then tighten finger-tight only -- do not overtighten.

5. Restore power, run a test cut on scrap material, and inspect the kerf and gas jet before production.

Store nozzles in their original packaging in a dry place. Keep the bore and thread clean; oil or fingerprints on the orifice can contaminate the gas flow and affect cut quality.

Frequently Asked Questions

What laser heads fit the HALANSM® HLN-SUP-D28H15M11 supersonic nozzle?

Any head that accepts a 28mm OD x 15mm height x M11 nozzle is mechanically compatible. The most common matches are Han's / DNE and Hongshan high-power heads. Send your head model and original part number for a confirmed fitment check.

Why choose a supersonic (converging-diverging) bore over a standard nozzle?

The de Laval profile reaches supersonic gas speed, which clears molten material faster and gives a cleaner lower edge with less dross. It is most effective on medium to thick plate at high feed rates.

What orifice size should I pick for carbon steel?

Use 1.2-2.0mm for thin sheet with oxygen, 2.5-3.5mm for medium plate, and 4.0-7.0mm for thicker material on high-power machines with nitrogen or air. Your machine settings and gas pressure should be matched to the chosen orifice.

Is the HLN-SUP-D28H15M11 an original OEM part?

No. It is an aftermarket replacement manufactured to the published interface dimensions. It is not affiliated with nor endorsed by the original head manufacturers, and no OEM authorization is claimed.

How do I avoid cross-threading when installing the M11 nozzle?

Always start the thread by hand until it seats without resistance, then tighten finger-tight. If you feel resistance, back off and re-align -- forcing the M11 thread will damage both the nozzle and the head seat.

What causes poor cut quality after replacing the nozzle?

The most common causes are a mismatched orifice for the material thickness, contamination on the bore, a damaged ceramic ring, or an incorrectly seated nozzle. Verify the thread, clean the assembly, and run a test cut on scrap before resuming production.
