Laser Drilling

Precision laser drilling with high-energy beams offers a non-contact method for creating micro-holes in quartz tubes. This technique allows for extremely small diameters, precise positioning, and smooth edges. It is ideal for fabricating high-precision, high-density hole arrays in fused silica or quartz tubes, without causing any mechanical stress or damage to the material. Laser micromachining ensures minimal heat-affected zones and tight tolerances for critical applications.

Quartz Tube FAQ

1.Outer Diameter, Wall Thickness, and Length: These three parameters determine the weight of the quartz tube. A greater weight indicates more raw materials used, naturally leading to a higher price.

2.Purity of the Quartz Tube: Higher purity necessitates more advanced purification techniques for the quartz sand and a more complex manufacturing process, resulting in a higher price. We offer high purity (99.99%) quartz tubes.

3.Order Quantity: The quantity purchased directly impacts the price. Bulk orders often receive discounts. 

4.Customized Sizes: Non-standard or unique dimensions with higher material wastage will also affect the price. We offer custom fabrication services for quartz tubes. 

5.Special Dimensions and High Precision Requirements: If CNC machining or secondary shaping processes are required, the price will increase.

Yes, absolutely! When purchasing quartz products, volume purchasing power translates directly into significant price advantages, primarily in two key areas:

Firstly, considering production costs, fixed expenses like design and programming are distributed across a larger number of units. This reduces the per-unit cost allocation, resulting in a more competitive unit price.

Secondly, leveraging economies of scale, bulk orders enable us to maximize the benefits of large-scale manufacturing. We achieve greater efficiencies in raw material sourcing, streamlining production processes, and optimizing logistics. These cost savings are directly reflected in our pricing, providing you with significant economic benefits

Therefore, bulk purchasing of quartz products not only provides you with more favorable pricing but also ensures consistent product quality, thus maximizing your overall purchasing value. We offer volume discounts on all of our quartz products, including quartz tubes, rods, and custom-fabricated components.

Yes, we can. Our company offers comprehensive, one-stop export services to our international clients. We have a streamlined process for export transactions:
Detailed Quotation: We provide a detailed quotation that includes comprehensive product specifications, pricing terms (Incoterms), packaging details, and other relevant information.
Formal Sales Contract: We create a standardized sales contract that clearly defines the rights and responsibilities of both parties, ensuring a transparent and legally sound agreement.
Expert Export Guidance: We offer professional guidance throughout the entire export process, including customs declaration procedures, optimal transportation methods, and all necessary documentation requirements.

Order Quantity: The number of units ordered.
Tube Dimensions and Specifications: The specific size and characteristics of the quartz tube.
Technical Requirements: Including the required precision grade (e.g., tolerances). 
Additional Processing Needs: If any secondary processing is required.
For Standard Specification Products: Lead times are primarily determined by the order quantity. Please contact us for specific lead time estimates. 

Please Note: 
Custom Specifications: Customized or non-standard quartz tubes may require additional production time.
Secondary Processing: Operations such as cutting, polishing, or fire polishing will typically extend the lead time by approximately 3-7 business days.
High Precision Requirements: Products requiring very high precision may necessitate an additional 5-10 business days for quality control and inspection.
We strive to provide the fastest possible turnaround times while maintaining the highest quality standards. For a precise lead time estimate, please provide us with your specific requirements.

For Standard Specification Quartz Tubes:
We maintain a large inventory of over 500 standard specifications, covering more than 90% of commonly used sizes.

Yes, we specialize in custom fabrication of quartz tubes to meet your exact specifications.
Standard Quartz Tube Customization: 
We offer customization within the following parameter ranges:
Outer Diameter (OD): 1mm – 500mm
Wall Thickness (WT): 0.25mm – 30mm
Length (L): 1mm – 5000mm
Tolerance Grade: Options ranging from ±0.1mm to ±1mm

We have a flexible approach to Minimum Order Quantities (MOQs), depending on the type of customization:
For Custom Dimensions (Outer Diameter/Wall Thickness):
MOQ: 500kg
Reason: This type of customization typically requires creating a new mold and adjusting our production processes.
Recommendation: For initial orders, we recommend starting with 500kg. Larger volume orders placed subsequently will qualify for more competitive pricing.
For Custom Lengths (Cutting Only):
No MOQ: We do not have a minimum order quantity for custom length cuts. 
Small Batch Orders Welcome: We support small batch orders for length customization
Cutting Accuracy: ±0.5mm
Advantages: No mold creation is required, and the production turnaround time is typically 1-3 days

We maintain strict quality control over the materials and manufacturing processes of our quartz products. You can be confident that there will be no issues with the temperature resistance of our tubes.
Our Responsibility: If, upon receipt, you find any agreed-upon quality issues such as cracks, bubbles, impurities, or dimensional deviations, our company will take full responsibility.
Transportation Damage: In the event of damage caused by impacts or mishandling during shipping, we will promptly replace the damaged products.
Documentation: Please take photos or videos and document the specific nature of any quality issues or damage. This will greatly assist us in resolving the matter quickly and efficiently.
