Frequently Asked Questions

Find answers to commonly asked questions about our products and services.

Are you a direct manufacturer or a distributor of quartz glass?

Aoxin Quartz is a direct manufacturer of quartz glass products. We handle the entire process from raw material selection (or sourcing) to final fabrication and quality control at our own facility located in China.

What grades/purity levels of quartz glass do you offer?

We offer various grades to meet different application needs, including standard purity fused quartz, high-purity fused quartz (e.g., for semiconductor applications), synthetic fused silica (JGS1, JGS2, JGS3 equivalents), and opaque quartz. Please specify your application or required purity level (e.g., SiO2 content > 99.99%) when requesting a quote.

Do you accept custom orders based on drawings? What is the process?

Yes, custom fabrication is a core part of our business. The typical process is:
1. You provide detailed drawings (e.g., CAD files like DWG, STEP) and specifications (material grade, tolerances, quantity).
2. Our engineering team reviews the feasibility and provides technical feedback if necessary.
3. We provide a formal quotation including price and estimated lead time.
4. Upon order confirmation, we proceed with manufacturing according to the approved drawings.
5. Quality inspection is performed before shipment.

Please send your drawings to [email protected] or use our quote request form.

What is your Minimum Order Quantity (MOQ)?

Our MOQ varies depending on the product type and complexity. For standard items like tubes or rods, we might have lower MOQs compared to highly customized precision components. Please contact our sales team with your specific requirements for details.

What is the typical lead time for custom and standard products?

Lead times depend on product complexity, quantity, and current production schedules. Standard items might ship within 7 days. Custom orders typically range from 1 to 4 weeks after drawing approval. We will provide a specific estimated lead time with your quote.

Can you provide material certifications or Certificates of Conformance (CoC)?

Yes, we can provide material certifications detailing the properties (like purity) and Certificates of Conformance upon request, confirming that the products meet the specified requirements and standards.

How can I get a quote? What information is needed?

The best way is to use the “Request a Quote” form on our website or email us at [email protected]. Please provide as much detail as possible:
1. Product type (tube, plate, rod, custom part, etc.)
2. Material grade/purity requirement
3. Dimensions and tolerances (drawings are preferred for custom parts)
4. Quantity needed
5. Application (helps us understand the context)
6. Your contact information

Do you provide samples?

Samples for standard materials or simple items may be available, sometimes at a cost depending on the item. For custom components, prototyping might be part of the development process. Please discuss your sample needs with our sales team.
