ZHHIMG, a leading manufacturer in precision measurement tools, has officially launched its ultra-precision ceramic square ruler, marking a significant breakthrough in industrial measuring tool technology. This innovative product is set to redefine standards in aerospace and semiconductor manufacturing, where precision requirements have reached unprecedented levels.
Constructed from 99.5% high-purity alumina ceramic, the new square ruler achieves remarkable precision with flatness and straightness errors controlled within 1μm per 1000mm, and squareness within 2μm—representing a 3.5-fold accuracy improvement compared to conventional granite tools. The material’s exceptional hardness (≥1100 HV3) provides five times the wear resistance of metal tools, ensuring long-term precision retention without degradation over time.
A key advantage lies in its thermal stability, with a thermal expansion coefficient of 3.2×10⁻⁶/℃—only one-fifth that of stainless steel—maintaining sub-micron accuracy even in temperature-fluctuating environments. Weighing 50% less than equivalent granite tools while maintaining 380 GPa rigidity, the ruler significantly reduces operator fatigue during extended use. Its non-porous surface offers superior corrosion resistance, making it ideal for semiconductor cleanrooms and aerospace manufacturing facilities.
Timed to meet booming demand in precision manufacturing, the global measurement instrument market is projected to grow at 5.5% CAGR through 2031. In aerospace, where “zero defect” standards require ≤2μm accuracy for aircraft frames and turbine blades, and semiconductor manufacturing with 3nm node processes, ZHHIMG’s tool eliminates metal contamination risks while delivering critical measurement reliability.
Backed by 25 years of expertise, ZHHIMG’s 160-hectare production complex in Shandong Province offers 50-ton processing capabilities and flexible global shipping via Qingdao Port. The product meets ISO 9001, CE, and TUV certifications, with each unit accompanied by an ISO 17025 calibration report and industry-leading 1-year warranty—strengthening its position in China’s rapidly expanding ceramic measuring tool market, projected to reach RMB 1.5 billion by 2030.
Available in custom sizes from 200×200mm to 1000×1000mm, this ultra-precision ceramic square ruler delivers the reliability needed to push industrial measurement standards forward. Contact ZHHIMG today to discover how this breakthrough tool can enhance your production accuracy and efficiency.
