Ruby or sapphire jewels with hole size smaller than 0.08mm are classified in this category of micron orifice.
Micron orifice is made from synthetic Ruby and sapphire, which are single crystal materials with a hardness of 9 on the MOHS scale which makes it the most preferred hard material for commercial applications. Being extremely hard, the parts made from ruby and sapphire can attain a high degree of polish and can be machined into parts with micron accuracy.
Industrial jewels have the ability to manufacture the micro-hole orifice to extremely precise tolerance which can be fine-tuned in steps of 0.001mm.
Using world-class measuring instruments, industrial jewels can customize a highly reliable and cost-effective product.
Micro hole orifice made from ruby and sapphire is commonly used in industrial inkjet printers. For inkjet printing, it is necessary to spray the ink in the right volume and flow quality to obtain consistent printing results. The ruby or sapphire micro hole orifice can be manufactured to have holes with a tolerance of +/-0.002mm and a scratch-free surface finish which results in the exact quantity of ink flowing through the hole without being deposited on the orifice surface. In addition to this, as the ruby and sapphire material is extremely hard there is no wear on the surface of ruby or sapphire orifice.
Having extremely high chemical resistance, these micro hole ruby or sapphire orifices do not get corroded like some other hard materials.
The other industrial applications for these micro hole orifice is for micro-dosing of chemicals or fluids for analysis. Having precise and a wear-resistant surface, a limited quantity of fluids can be consistently dosed through this orifice. In some cases, fluids are passed at high pressure of up to 5000 bars to obtain a laminar flow of fluid for water jet cutting and cleaning applications.
