VTY (Tianyue) operates a production facility equipped with 134 CNC machines, including MAZAK machining and milling centers, as well as robotic manipulators for automated processing. These machines are used for machining sanitary sight glass components with controlled dimensions and repeatable accuracy. Welding and pipe fitting polishing processes are carried out in dedicated workshops to achieve smooth internal and external surfaces suitable for hygienic applications.
Quality control follows an ISO 9001-certified system. Inspection is conducted in an in-house laboratory equipped with 3D coordinate measuring machines, hardness testers, and surface roughness testers. Each sanitary sight glass is inspected for material grade, wall thickness, dimensional tolerances, and surface finish before release.
Most products are exported to European markets, which account for approximately 95% of shipments, and quality requirements are applied according to customer specifications and relevant industry standards.
