HALANSM® D18 H20 M9 3D Laser Nozzle
Aftermarket copper 3D nozzle for tube and 3D fiber laser cutting heads
HALANSM® HLN-3DM9-D18H20 is an aftermarket 3D laser cutting nozzle sized OD 18 mm x height 20 mm x thread M9, built for Gangchun and compatible 3D tube-cutting heads to deliver stable assist-gas flow and clean cuts on round, square, and shaped tubes.
Product Overview
The HLN-3DM9-D18H20 mounts at the front of a 3D tube-cutting laser head. Its bore directs assist gas to eject molten material while the head pivots around the tube profile. A concentric bore and accurate M9 thread keep the focal point stable through complex 3D contours.
Key Advantages
High-Purity Copper Body
Machined from high-purity copper for strong thermal and electrical conductivity during continuous cutting.
Single or Double Layer
Available in single layer for nitrogen cutting and double layer for oxygen and thick-plate work. Confirm exact specs with us.
Precision Bore, Smooth Flow
Polished inner wall maintains laminar gas flow for clean edges and less spatter.
Knurled Mounting Seat
Toothed flange grips the ceramic seat securely and resists loosening under vibration.

Selection Guide
Use 1.25 - 1.5 mm for thin-wall tube with nitrogen, and 2.0 - 3.0 mm for thicker wall with oxygen. Confirm exact specs with us for your material and gas.
Choose single layer for nitrogen and fine-finish cutting; choose double layer for oxygen and heavy-duty cutting. Confirm exact specs with us.
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 M9 thread and hand-tighten the new nozzle; do not overtighten.
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-3DM9-D18H20 3D nozzle?
It fits Gangchun and compatible 3D tube-cutting heads with an M9 nozzle interface. Provide your head model and original part number for exact fitment.
Is the HLN-3DM9-D18H20 an original Gangchun part?
No. It is an aftermarket replacement made to the D18 H20 M9 form factor. Gangchun is a third-party trademark used only for fitment identification.
What material is the HLN-3DM9-D18H20 made of?
High-purity copper with a polished bore. Layer type and surface finish vary by SKU; confirm exact specs with us.
How do I choose the right bore caliber?
Use 1.25 - 1.5 mm for thin-wall tube with nitrogen and 2.0 - 3.0 mm for thicker wall with oxygen. Confirm exact specs with us.
When should I replace the 3D nozzle?
Replace it when the bore clogs with slag, the tip deforms, or cut quality drops. Timely replacement protects the ceramic ring.
Can I install the HLN-3DM9-D18H20 myself?
Yes. Power down, remove the old nozzle, clean the seat, hand-tighten the new nozzle, recalibrate the sensor, and test cut.
