Granite Straight Ruler
1. Semiconductor wafer inspection and lithography equipment
In the installation and calibration of the guide rails of the motion platform, the ZHHIMG straight ruler serves as a "geometric reference" for detecting the straightness and parallelism of the moving pairs. Without it, the high-speed moving precision sliders would lose their sense of direction.
2. Flexible Display and OLED Production
In the manufacturing process of large-sized panels, ensuring the flatness of the racks spanning several meters is of critical importance. Our long-scale granite straightedges can provide highly accurate plane references over an extremely large span.
3. Aerospace and Optical Alignment
In the assembly of satellite components or high-magnification optical lenses, the high-precision measurement accuracy (00 grade or 000 grade) provided by ZHHIMG serves as the final safeguard to ensure that product performance meets the standards.

In high-precision fields, metal materials often falter due to thermal expansion and contraction or internal stress, while our granite straightedge demonstrates nearly perfect physical properties:
1. Ceiling of physical stability: Made of high-quality Jinan green stone that has undergone natural aging for hundreds of millions of years, all internal stresses have been fully released. Even in fluctuating environments, it remains as stable as a mountain and does not deform over time like cast iron or steel.
2. Extremely low coefficient of thermal expansion: Even with strict temperature control in semiconductor workshops, minor temperature fluctuations pose challenges. Granite has an extremely small coefficient of thermal expansion, ensuring the repeatability of test results.
3. High hardness and corrosion resistance: It has a high Mohs hardness and strong wear resistance. More importantly, it does not rust, magnetize or stick to sand, fully meeting the strict environmental requirements of Class 1000 and Class 100 cleanrooms.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)
1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).
2. Special Export Plywood Case: Export fumigation-free wooden box.
