The Long-Focus Water-Cooled Coaxial 4-Stream Laser Cladding Nozzle dari Greenstone direkayasa untuk kelongsong laser DED / LMD efisiensi tinggi on large components where long working distance, high deposition productivity, dan stable coating quality are essential. Compared with conventional coaxial annular dan 3-point designs, this 4-stream coaxial nozzle delivers a tempat bubuk yang lebih besar dan kebuntuan yang lebih lama, making it especially effective for high-speed cladding and large-area surface processing.

Its optimized coaxial powder delivery forms a concentrated, controllable powder focus that can be precisely matched to the laser spot. When paired with high-power, large-spot laser sources, the nozzle helps achieve higher cladding efficiency while maintaining stable melt pool behavior and consistent layer formation. The water-cooling structure supports long-duration operation and contributes to masa pakai yang lebih lama, reducing downtime and improving production continuity in demanding industrial environments.

Dengan 30–31 mm working distance dan 2–4 mm powder spot size, this nozzle is well-suited for large workpiece repair, remanufacturing, and surface strengthening—including wear-resistant overlays, corrosion-resistant coatings, and heavy-duty component restoration where process stability and repeatability matter.
