HALANSM® Hongshan D28 Laser Nozzle, OD 28 mm x H 15 mm x M11
Aftermarket copper D28 H15 M11 single or double layer nozzle for Hongshan and compatible fiber laser cutting heads
HALANSM® HLN-HS-D28H15M11 is an aftermarket laser cutting nozzle sized OD 28 mm x H 15 mm x thread M11, built for Hongshan (HSG) and compatible fiber laser cutting heads to deliver stable assist-gas flow and clean cutting on mild steel, stainless steel and aluminum.
Product Overview
HLN-HS-D28H15M11 mounts at the front of the cutting head above the ceramic ring or nozzle seat. Its bore and gas-channel geometry control assist-gas coverage, directly affecting dross, slag adhesion and edge quality. Replacing a worn nozzle restores stable airflow and cutting performance.
Key Advantages
High-Purity Copper
CNC-machined copper body offers strong thermal and electrical conductivity to dissipate heat during high-speed cutting.
Single or Double Layer
Available in single and double layer. Use single layer with nitrogen for bright edges, double layer with oxygen for thicker carbon steel.
Optional Chrome Plating
Chrome-plated bore improves surface hardness and wear resistance. Confirm exact specs with us.
Batch Consistency
Bores are inspected for concentricity, so repeat orders stay dimensionally consistent.
Compatible with aftermarket Hongshan (HSG) and other cutting heads using a D28 H15 M11 nozzle form factor. Also cross-referenced against DNE-compatible nozzles of the same D28 H15 dimensions. Provide your head model and original part number for fitment check.
Selection Guide
Match outer diameter, height and thread first: this nozzle is D28 x H15 x M11. Then choose bore caliber by material and gas. The same D28 diameter appears with different threads, so always confirm the thread before ordering.

Installation and Handling
1. Power down the laser and release all assist-gas pressure.
2. Unscrew the worn nozzle from the ceramic ring or nozzle seat.
3. Clean the mounting seat and ceramic interface with a lint-free cloth.
4. Align the M11 thread by hand, then tighten only until snug.
5. Recalibrate the capacitive sensor, then run a low-power test cut on scrap.
6. Store spares in a dry, sealed container away from dust and moisture.
Frequently Asked Questions
What laser heads fit the HALANSM® HLN-HS-D28H15M11 Hongshan nozzle?
It fits Hongshan (HSG) and compatible heads using a D28 H15 M11 nozzle. Provide your head model and original part number for fitment check.
Is the HLN-HS-D28H15M11 an original Hongshan nozzle?
No. It is an aftermarket replacement made to the D28 H15 M11 form factor. Hongshan is referenced only for fitment identification.
What material is the HLN-HS-D28H15M11 made of?
It is machined from high-purity copper, with optional chrome plating for wear resistance. Confirm exact specs with us.
How do I choose between single and double layer?
Use single layer with nitrogen for bright, dross-free edges; double layer with oxygen for thicker carbon steel.
When should I replace the D28 nozzle?
Replace it when slag blocks the bore, the tip deforms from heat, or cut quality declines. Timely replacement protects the ceramic ring.
Can I install the HLN-HS-D28H15M11 myself?
Yes. Power down, remove the old nozzle, clean the seat, hand-tighten the new nozzle, recalibrate the sensor, and test cut.
