The client in this collaboration operates in the optical component processing and inspection industry, primarily manufacturing lens elements, prisms, light guide plates, laser modules, and optical coating components. The company relies on optical measurement platforms to inspect lens curvature, thickness, light transmission profiles, and assembly clearances, and is extremely sensitive to vibration and airflow disturbances. The optical measurement platform features a granite surface with high rigidity, which makes it prone to resonance that amplifies vibration. The platform is enclosed within a fully sealed aluminum profile protective frame housing a high-speed scanning lens. Airflow from the plant's air compressor and workshop ventilation systems, combined with ground vibrations, create dual interference. Conventional isolation products only address solid‑borne vibration and cannot simultaneously dampen the microscopic table displacements caused by airflow fluctuations, resulting in wavy deviations in continuous scanning images.
Solution
In response to the above issues, Liva Shanghai's large-scale industrial air‑floating vibration isolation optical measurement platform damping project has been successfully completed and closed out. Our Shanghai team has completed the bulk supply of VC‑type pneumatic isolators, with all damping products having undergone on‑site installation at the plant, air line connection, leveling, and vibration measurement and commissioning.
Core Product Advantages
Ultra-low 2 Hz natural frequency
2±0.05 mm automatic leveling compensation
Adjustable damping flow control valve
Safety pressure relief valve
Long-term stable operation
Based on its long-term development strategy, Liva will continue to uphold independent technological innovation, strictly control product quality throughout the entire lifecycle, and continuously iterate and optimize the low-frequency isolation performance and environmental adaptability of its spring, rubber, and pneumatic isolators. The company will actively engage with upstream and downstream enterprises in the integrated circuit and precision semiconductor manufacturing supply chains, providing customized vibration isolation solutions for high-precision equipment such as optical inspection systems, coordinate measuring machines, and wafer inspection equipment. By delivering reliable domestically produced isolation products, Liva aims to support the steady advancement of China's semiconductor industry toward self-reliance and large-scale development.
