Applied Laser Engineering (ALE) has developed a new laser engraving nozzle by combining results from Computational Fluid Dynamics Software (CFD) and physical testing.
The new high performance nozzle fits on existing MBF/MBL style nozzles. Its uniquely developed design has the following benefits:
- Cleaner work area & roller surface
- Eliminate nozzle debris build-up
- Deeper engraving depth*
- Increased quality of the engraving*
*exact result will depend on the engraving type
New Nozzle Design
The developed nozzle has been carefully designed to improve the airflow characteristics. It comes with 3 standard shroud sizes: Ø80, Ø220 & Ø600 mm. Each size is designed to provide optimal performance at that specific diameter. With the Snap-On/off design it makes switching shrouds simple and easy. If required, special diameter shrouds can be manufactured for anything that is nonstandard. The new design fits in the same form factor as the previous MBF/MBA/MBL nozzle.
Enhanced Extraction Effectiveness
IMPROVED AIRFLOW
The primary initial focus of the redesign was to improve airflow utilisation and reduce turbulence. Using computational fluid dynamic simulations, the airflow paths, velocity’s, pressures, and many other parameters were compared. This allowed ALE to investigate what factors improved designs and how this can be used to refine the design and to quantify parameters and compare why certain designs have issues in specific areas.
Reduce Roller Surface Redeposition
COMPARISON
Improved airflow and extraction effectiveness dramatically reduces the ablated material that is redeposited on the surface.
