1. Gem nozzle This nozzle is commonly used in early inkjet printers. The nozzle is extruded into a stainless steel outer circle with a diameter of about 2 mm. The gemstone has a hole with a diameter of 30-80 μm.
2. Stainless steel nozzles are now used by most manufacturers. The stainless steel nozzle is made of a stainless steel disc with a diameter of about 5 mm and a thickness of 1 mm. On the top, a hole with a diameter of 30-80 μm is burned by laser.
Comparison of the nozzles of the two nozzles:
1. Production process gemstone nozzle In the production process, the gemstone piece is easily crushed, which is more complicated. The stainless steel inkjet printer is relatively simple, as long as the laser is used to punch holes in the stainless steel piece.
2. The smoothness of the gemstone nozzle is relatively high, there is no burr. The stainless steel nozzle is burnt by laser, the burr is generally more, not smooth. However, by grinding, the finish can also reach the level of the gem nozzle.
3. Adjusting the breakpoint of the gemstone nozzle Because the distance between the gemstone piece and the crystal shock is not fixed (the depth of the gemstone in the outer circle of the stainless steel is determined by the strength of the extrusion process), it is troublesome to adjust the good breakpoint. The thickness of the stainless steel nozzle is due to the thickness. Consistent, basically as long as the grinding is better, it is easy to break out a good point.
4. Cost comparison Gems nozzles are much more expensive than stainless steel nozzles.
