The global high-end intelligent manufacturing industry is evolving at a rapid pace. Mass-production lines for semiconductor wafer inspection, lithium batteries and perovskites have raised brand-new performance requirements for reference inspection substrates. Ordinary metal worktables suffer severe thermal expansion and contraction, while generic stone materials wear easily and suffer rapid loss of reference precision. These flaws readily lead to deviated inspection data and lower production yields. Specializing in the R&D and production of ultra-precision metrology substrates, UNPARALLELED has launched a full range of finely crafted granite metrology plates. Leveraging exclusive stone formulations, refined dust-free manufacturing processes and a complete metrology calibration system, we deliver long-lasting, stable high-precision reference support for the entire semiconductor and new energy industrial chains.
Our plates are manufactured from self-developed exclusive high-density black granite. Its compact internal structure delivers an ultra-low thermal expansion coefficient, with superior friction and deformation resistance compared to ordinary marble available on the market. The flatness of the work surface will not degrade even under long hours of continuous inspection operations. We uphold integrity as our core business principle and never substitute low-cost inferior stone for premium raw materials. Every batch of raw stone undergoes sampling physical performance testing to guarantee long-term product stability from the source of production.
Our enterprise holds a full suite of internationally authoritative certifications and has registered patents and trademarks across multiple overseas regions. All products are manufactured in strict compliance with universal precision manufacturing standards worldwide, ensuring full regulatory compliance for export to all global markets. Our manufacturing base is located close to a port city with convenient sea and land logistics. We operate two large-scale production plants paired with dedicated raw material storage yards. Our ample production capacity supports simultaneous fulfillment of small and medium-volume standard orders as well as oversized custom projects. Equipped with multiple high-end large grinding machines and heavy-duty CNC machining units, our factory enables integrated processing of oversized, heavy-tonnage granite plates, flexibly meeting custom dimension requirements for equipment across diverse industries.
To achieve nanometer-level metrology precision during production, we have built an independent semiconductor-grade constant-temperature, constant-humidity, dust-free and vibration-isolated workshop. Multiple design features - thickened military-grade concrete flooring, circular anti-vibration trenches and silent overhead cranes - eliminate interference from vibration, temperature and humidity fluctuations that compromise machining precision. All fine grinding, precision calibration and finished product inspection of granite plates are completed within this dust-free environment, minimizing precision errors caused by environmental factors.
We firmly believe accurate inspection is the cornerstone of premium products. Our production line is fully equipped with imported high-end metrology instruments. All testing equipment is regularly calibrated by official metrology institutions, with fully traceable inspection data. Every granite plate undergoes multiple rounds of repeated precision verification before shipment. Products are only released once core indicators including flatness and parallelism fully meet standards, accompanied by complete inspection reports delivered to clients. 
Our production and technical teams regularly receive training on international metrology standards. Frontline polishing technicians possess decades of hands-on precision grinding experience, utilizing consummate craftsmanship to produce ultra-flat work surfaces. We maintain continuous technical collaboration with top domestic and international universities and national metrology research institutes. Joint innovation drives constant optimization of core processes including stress relief and precision grinding for granite components, pushing the technical limits of high-precision metrology substrates.
Our precision granite metrology plates are perfectly compatible with various equipment in two core industries: semiconductors and new energy. For semiconductor production lines, they serve as reference worktables for AOI optical inspection, X-ray flaw detection, coordinate measuring machines (CMM) and wafer inspection equipment. In the new energy sector, they fit lithium battery component inspection, perovskite coating machines, new energy tool inspection equipment and more. We also supply a full set of metrology measuring tools including granite surface plates, square rulers and V-blocks. Their nanometer-level flatness satisfies multiple application scenarios including equipment assembly, precision calibration and laboratory metrology.
Over the years, our stable, high-quality granite metrology plates have earned us an extensive global customer base. Our partners include multiple Fortune 500 manufacturing enterprises and leading international precision transmission brands. We also maintain long-term stable cooperation with numerous domestic and international metrology research institutes, universities and overseas government and enterprise organizations. Our products are exported across the globe and widely recognized throughout the industry.
Semiconductors and new energy represent the core growth sectors of global high-end manufacturing. High-precision metrology references are critical foundations for stable mass production and improved product yields. UNPARALLELED will continue to focus on precision inspection demands within these two industries. We will deepen technological innovation for granite metrology plates, upgrade supporting facilities for dust-free constant-temperature precision manufacturing, and optimize full-process quality control standards. Moving forward, we will keep delivering customized high-stability, wear-resistant, ultra-precision granite metrology plate solutions to intelligent manufacturing enterprises worldwide, empowering long-term, high-quality development of the global semiconductor and new energy industries through precision substrate technology.
