Opaque circular frosted perforated quartz plate is a functional plate made of high-quality quartz material and precision processed. It integrates the excellent physical properties of quartz materials with professional surface treatment and drilling processes, aiming to provide reliable solutions for various precision equipment and high-end applications.

Core features and solved problems:

Excellent durability and stability (solving problems of easy wear and deformation)

High hardness and wear resistance: Quartz plate has a high Mohs hardness, far exceeding glass and stainless steel, which can effectively resist scratching and wear. It can maintain a smooth surface even after long-term use, solving the problems of ordinary materials being easily scratched, affecting aesthetics and accuracy.

Extremely low coefficient of thermal expansion: extremely insensitive to temperature changes, even in harsh environments with alternating cold and hot temperatures, it will not undergo significant deformation or cracking, ensuring the alignment accuracy of the components installed on it and solving the problem of inaccurate measurement or operational failures caused by thermal expansion and contraction.

Corrosion resistance and aging resistance: It has excellent resistance to acid, alkali and other chemical reagents, is not easy to be polluted and corroded, and has a long service life.

Unique surface treatment (addressing issues of light interference, aesthetics, and cleanliness)

Opaque frosted surface: The surface is finely frosted to create a uniform, soft, and matte texture. This not only gives the product a high-end appearance, but more importantly, it can effectively prevent glare, eliminate light spots, provide a uniform background for devices such as lasers and optical sensors, avoid stray light interference, and improve detection and measurement accuracy. Meanwhile, the frosted surface is more resistant to fingerprints and stains, making it easy to clean and maintain.

Precise drilling process (solving installation and positioning problems)

High precision hole positioning: CNC (computer numerical control) technology is used for drilling, with hole positioning accuracy of ± 0.05mm or even higher, ensuring perfect alignment and seamless integration with installation components such as sensors, lenses, indicator lights, screw columns, etc.

Diversified hole types: Various hole types such as through holes, blind holes, countersunk holes, threaded holes, etc. can be processed according to needs to meet the needs of different installation methods and concealed wiring.

Customized design: The size, quantity, and distribution pattern of the holes can be customized according to the drawings, providing high flexibility to solve your specific structural design problems.

Main application areas

What problems can the product solve?

Limitations of traditional materials:

Replace ordinary glass: avoid the risk of hydrofluoric acid corrosion, have higher density (2.65g/cm ⊃3; vs 2.4-2.5g/cm ⊃3;), and improve impact resistance by three times.

Alternative metal materials: eliminate electromagnetic interference, suitable for high-precision optical and electronic devices.

Pain points in usage scenarios:

Laboratory safety: Explosion proof and high temperature resistance characteristics reduce the risk of chemical leakage.

Industrial efficiency: Precision drilling reduces fluid resistance and enhances microreactor processing capacity.

Maintenance cost: Anti fouling coating reduces cleaning frequency by 70%, and long-term use only increases surface roughness by 0.3 μ m/decade.
