Micro Hole Orifice from Sapphire/Ruby, which are used in various control applications of hydraulics, water, chemicals and airflow.
A 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’s design and specifications. New entrants in this field can be helped by our engineering department to design nozzles to work under different pressure.
