Although the nozzle is not the core component of the inkjet printer, it is closely related to the service life and work efficiency of the inkjet printer. When printer manufacturers produce these nozzles, they usually use ruby u200bu200bnozzles and stainless steel nozzles. As far as the production process is concerned, the ruby u200bu200binlay process is more complicated, which has high technical requirements for the producer and large production environment requirements. For stainless steel, you only need to drill holes in the stainless steel with a laser. As far as work efficiency is concerned, ruby u200bu200bhas a high finish and no burrs. Because the stainless steel nozzle is laser burned and perforated, the finish and smoothness cannot be compared to the gem nozzle, even after careful polishing, there will be a certain difference. Therefore, in the process of use, the smooth support of ink is completely different, especially when using pigment-based inks, the effect is more significant. In terms of usage time, since there are inks and adhesives in the ink, these contain a large amount of organic matter, so the corrosiveness must not be low. The corrosion resistance of stainless steel is not strong, so after a period of use, the nozzle clogging phenomenon will appear frequently. Ruby is naturally formed, has high hardness and corrosion resistance, so it can be used for a long time with simple maintenance. And the effect and stability of the spray will be much better than the stainless steel nozzle. The value of ruby u200bu200bis much greater than that of stainless steel, so it will be slightly higher in price. However, the quality of the nozzle is indeed extremely important to the performance and service life of the machine, so these factors need to be considered comprehensively.
