As a key material in industrial manufacturing and scientific research, the accuracy of quartz rods directly affects the performance and reliability of the final product. For global buyers seeking high-precision quartz rods, choosing a factory with strong technology and strict quality control is crucial.

Core application areas of high-precision quartz rods

High precision quartz rods are not ordinary materials, and their application scenarios have strict requirements for dimensional tolerances, roundness, straightness, and surface smoothness:

-Semiconductor manufacturing: used for carrying rods in diffusion furnaces and oxidation furnaces, with an accuracy deviation of less than ± 0.05mm to ensure wafer transport stability.

-Optical instruments: As supporting or guiding components of optical systems, the straightness requirement is often higher than 0.1mm/m.

-Laboratory equipment: High purity quartz rods are used as sample supports in high-temperature environments (such as above 1200 ℃), requiring extremely low thermal expansion coefficients.

-Medical devices: used as precision structural components in high-end medical equipment, requiring no bubbles, no impurities, and compliance with biocompatibility standards.

Core production standards for high-precision quartz rods

High precision quartz rods must meet the following technical specifications:

1. Dimensional accuracy: The diameter tolerance can be controlled within ± 0.02mm, and the length tolerance can reach ± 0.1mm.

2. Geometric accuracy: straightness ≤ 0.05mm/m, roundness ≤ 0.01mm.

3. Material purity: SiO ₂ content ≥ 99.99%, critical applications need to reach 99.998% or above.

4. Thermal stability: The coefficient of thermal expansion is as low as 5.5 × 10 ⁻⁷/℃, ensuring no deformation at high temperatures.

5. Surface quality: Surface roughness Ra ≤ 0.4 μ m, no scratches, no microcracks.

Why choose us? ——Advantages of professional custom quartz manufacturers

As a customized quartz product manufacturer specializing in foreign trade, we have the following core advantages in the field of high-precision quartz rods:

1. Precision machining technology system

-Using CNC numerical control laser cutting and precision grinding technology, combined with a self-developed calibration system, to ensure consistency in mass production.
