Industrial jewels for nozzle orifice

Industrial artificial sapphire and ruby are gem-quality synthetic forms of Al2O3 or Corundum with a hardness of 9 on the Moh's hardness scale which is second only to diamond, they are extremely durable and wear resistant, besides, they features zero porosity, high degree of polish, heat resistant, low friction coefficient, chemical inertness and shock resistant. The durability and hardness of corundum makes synthetic ruby and sapphire resistant to abrasion and damage, thus, they are quite suitable to work under ultra-high pressure water environment and are adopted for orifice of nozzles including water-jet nozzle, spray nozzle, Ultra-dry fog nozzle, pin jet nozzle, needle jet nozzle and trim squirt nozzle.

Synthetic ruby orifice and synthetic sapphire orifice are nearly identical, they are the same hardness, same wear resistant, same sliding co-efficient of friction, same everything, except for the color. White sapphires are inherently transparent and more convenient for a visual inspection with a naked eye via microscope.

Unique Characteristics of Synthetic Ruby and Sapphire:

Single crystal	High thermal conductivity
Zero porosity	Heat resistant

Fluid Nozzle

We specialize in the manufacturing of the orifice jewel with Sapphire/Ruby, which are used in various control applications of hydraulics, water, chemicals and airflow.

We equipped well-controlled process ensures proper edges for inflow of material, followed by a precisely centered and polished hole to ensure proper flow of water or air. A high degree of accuracy and precision is required in the manufacturing of these parts as they work under extreme pressure.

These parts are manufactured as per customer抯 design and specifications. New entrants in this field can be helped by our engineering department to design nozzles to work under different pressure.
