Quartz rod wholesale supplier

In the fields of high-temperature operations, optical transmission, and semiconductor manufacturing, quartz rods are a fundamental and critical raw material, and their purity and dimensional tolerances directly determine the performance of the final product. As a professional wholesale supplier of quartz rods, we focus on the research, development and production of high-purity fused silica rods and synthetic quartz rods. Relying on stable raw material channels and precision machining capabilities, we provide standard and customized quartz rod solutions with outer diameters ranging from 2mm to 100mm for global optical, fiber optic communication, semiconductor, and laboratory equipment customers. We not only supply standard length quartz rods, but also specialize in high-precision cutting, grinding, and deep processing according to drawings, committed to becoming the most reliable quartz material source factory for global procurement partners.

Frequently Asked Questions (FAQ)

Q1: Can your quartz rod solve the problem of insufficient insulation in our company's high-temperature environment?

A: Absolutely possible. Our quartz rod is made of high-purity SiO ₂ (99.99% or above) material, with a long-term operating temperature of up to 1100 ℃ and a short-term use temperature of over 1200 ℃. It is an ideal insulation and support material for electric heating tubes and industrial furnaces.

Q2: I need an optical light guide rod with non-standard diameter and strict tolerance. Can you do it?

A: This is precisely our core service. We support customized design based on drawings, and through precise CNC machining and fire polishing processes, we can control the outer diameter tolerance of quartz rods within ± 0.05mm, meeting the stringent requirements for light guiding efficiency in the fields of laser devices and optical communication.

Q3: How to avoid semiconductor process contamination caused by material purity issues when purchasing quartz rods?

A: We are well aware of the sensitivity of the semiconductor industry. The semiconductor grade quartz rods we provide undergo strict purification processes and have extremely low levels of metal impurities. We can also provide detailed material testing reports along with the goods to ensure the stability of the materials in core processes such as diffusion and etching.

Q4: As a wholesale supplier, do you have a high minimum order quantity? Is small batch testing supported?

A: We encourage new customers to conduct small batch samples first. Although bulk procurement has cost advantages, our flexible customized service system supports various needs from single sample to bulk orders, helping you verify product compatibility first.

Product Core Advantage: Defining High Industry Standards

As a source manufacturer, our quartz rods have the following core competitiveness:

-High material purity: high-quality fused silica or synthetic quartz with SiO ₂ content ≥ 99.99%, few bubbles and even stripes, ensuring excellent spectral transmittance and radiation resistance.

-Full range of specifications and sizes: Regular inventory covers diameters from 3mm to 100mm, and lengths can be customized according to customer requirements. Large diameter quartz rods (such as those over 50mm) can also ensure roundness and straightness.

-Excellent temperature resistance: Its extremely low coefficient of thermal expansion (5.5 × 10 ⁻⁷/℃) enables it to withstand severe thermal shocks and is not easily exploded.

-Strong deep processing capability: We not only provide raw material rods, but also offer customized services throughout the entire process, including cutting, chamfering, end face polishing, punching, and slotting.

Multi industry application scenarios

-Optical communication and special optical fibers: as the basic consumables for fiber preform rods, or used as plug-in supports in the production of fiber optic connectors, they require uniform refractive index and low hydroxyl content.

-Semiconductor manufacturing: used to manufacture support frames for quartz boats, diffusion furnace tubes, and wafer carriers. Our materials can withstand corrosive gases such as high-temperature chlorine gas, avoiding contamination of wafers.

-Optics and laser technology: used as substrate materials for laser rods, high-power xenon lamp cores, or lens blanks for ultraviolet optical systems.

-Industrial heating and lighting: Core insulation components for infrared heating tubes, as well as end seals for ultraviolet sterilization lamps.

Customized service process

We are well aware that each customer's application scenario is unique. We offer:

-Size customization: Supports outer diameter of 2mm -200mm, with length accuracy controlled within ± 0.1mm.

-Surface treatment: transparent polished surface (for light guidance), frosted surface (for diffuse reflection) or precision polished surface.

-Alien processing: Processing round bars into L or U shapes through hot bending technology, or processing them into conical or spherical shapes at one end.

Customer Application Cases

Case 1: German Industrial Heater Manufacturer - High Temperature Insulation Rod Replacement Project

-Customer demand: The customer's original ceramic insulation rod is prone to brittle cracking under long-term 1200 ℃ working conditions, causing a short circuit in the heater. We need to find a more thermally stable alternative material that must comply with RoHS environmental standards.

-Solution: We recommend high-purity transparent quartz rods and cut the 25mm diameter quartz rods into precise lengths according to their drawings. The ends are chamfered and fire polished to eliminate edge stress.

-Final effect: After replacing the quartz rod, the failure rate of the heater was reduced by 90%. Customer feedback shows that the red hardness and heat shock resistance of quartz material far exceed those of ordinary ceramics, and its appearance is more beautiful. At present, the customer has listed quartz rods as a standard material for all high-temperature models.

Case 2: American semiconductor equipment refurbisher - customized high-precision quartz support column

-Customer requirement: We need to replace a batch of custom sized quartz support columns in the old diffusion furnace. The material batch must have high stability, minimal diameter tolerance, and be able to adapt to strong acid and alkali cleaning environments.

-Solution: Use a CNC grinder to precisely grind the outer diameter 12mm rod, ensuring that all support columns in the same batch have consistent dimensions and heights, and provide a comprehensive packaging solution to avoid scratches caused by friction during transportation.

-Final effect: Customer feedback shows that there is no need for secondary repairs during installation, and it can be used immediately after installation. The customer expressed in the thank-you letter, "Not only the product quality, but also your dedication to packaging details has shown us professionalism.

Case 3: Asian University Laboratory - Customized Optical Experiment Light Guide Rod

-Customer requirement: A physics laboratory at a certain university urgently needs a quartz rod with a length of 300mm, a diameter of 10mm, and optical grade polishing at both ends for low loss transmission of specific wavelengths of laser.

-Solution: Start the rapid sampling process, select synthetic quartz rods with low hydroxyl content, and use special polishing technology to achieve a mirror effect on the end face, with light transmittance meeting experimental requirements.

-Final effect: The experimental data collection was successfully completed, and the professor stated that the light guiding efficiency of the quartz rod was no less than that of a well-known brand previously purchased, but the delivery speed was nearly twice as fast.
