Micro Hole Orifice

A ruby microhole orifice is a small hole or opening made in a synthetic ruby gemstone that is typically used in various fluidic applications, such as inkjet printers, fuel injectors, and microfluidic devices. The microhole orifice is typically produced by using a laser or chemical etching process to create a precise and uniform hole in the ruby gemstone.

The use of a ruby microhole orifice provides several benefits over other materials, such as stainless steel or ceramic, including:

  1. High wear resistance: Ruby is one of the hardest materials known to man, which makes it highly resistant to wear and abrasion. This allows the ruby microhole orifice to maintain its shape and performance over long periods of use, resulting in more accurate and consistent fluid flow.

  2. Precise and uniform hole size: The laser or chemical etching process used to create the microhole orifice allows for extremely precise and uniform hole sizes, which is critical in many fluidic applications.

  3. Chemical resistance: Ruby is highly resistant to chemical attack, which makes it an ideal material for use in harsh or corrosive environments.

The use of ruby microhole orifices is particularly important in microfluidic applications, where precise and accurate control of fluid flow is critical. The small size and precise nature of the ruby microhole orifice make it an ideal choice for these types of applications, as it allows for highly accurate and consistent fluid flow control.
