Quartz Glass Tube Manufacturing Process
Raw Material Selection: The process begins with selecting high-purity quartz sand.
Melting Process: The quartz sand is heated in specialized furnaces at temperatures exceeding 2000°C, transforming the sand into a molten state.
Tube Formation: The molten quartz is shaped into tubes through a specialized process, typically using a rotational forming or drawing method.
Annealing: After the tubes are formed, they undergo an annealing process where they are gradually cooled in controlled conditions.
Cutting and Sizing: Once annealed, the quartz tubes are cut to the specific lengths required by the customer.
Surface Treatment: Depending on the application, the surface of the tubes may undergo additional treatments, such as polishing or etching.
Quality Control: Each quartz tube undergoes a thorough inspection to ensure it meets the required specifications.
Customization: Clients can request custom dimensions, wall thicknesses, and tube diameters to meet the needs of specific applications.
Final Packaging: After quality checks, the quartz tubes are carefully packaged to prevent contamination and damage during shipping.
