Company Profile
Packing & Delivery
Quality Control & Inspection
We use three-coordinate detectors, height gauges, electronic digital calipers, and measuring projector stress gauges to meticulously inspect product appearance and dimensions.
Custom quality metrics are integrated strictly per customer requirement. All testing data and QC reports are fully archived and traceable. Operators undergo rigorous training to serve as qualified quality inspectors, and all metrology tools operate under strict Measurement Systems Analysis (MSA) control.
Packaging Specifications
The product itself is wrapped securely with bubble wrap, with internal gaps fully shock-buffered with high-density foam. The exterior is crated in solid wooden boxes compliant with international export specifications. Specialized packing solutions can be arranged upon request.
Customized Branding Service
Equipped with high-precision in-house laser engraving systems, we provide custom text, part coding, and trademark/logo engraving directly on the quartz component according to your requirements.
Frequently Asked Questions (FAQ)
Can I have a sample order before bulk procurement?
Yes, we welcome sample orders to test and verify the purity, dimensional tolerance, and overall product quality before full production.
What is your typical delivery and lead time?
Standard lead time is generally within 15 days upon receipt of the initial deposit, depending on customization details and batch volume.
Do you have a Minimum Order Quantity (MOQ) requirement?
We maintain a low MOQ policy. A single piece (1 pc) is available for sample inspection and quality evaluation.
How is an order processed through your factory?
First, communicate your specific requirements or application scenario. Second, our engineering team supplies CAD drawings and formal quotes. Third, you confirm specifications and deposit for production. Fourth, we process manufacturing, inspection, and dispatch.
What shipping methods are available and what is the transit time?
For small parcels or urgent samples, express carriers such as DHL, UPS, FedEx, or TNT are utilized, taking approximately 3-5 days. Air cargo and sea freight logistics are provided for bulk commercial consignments.
Can you customize quartz parts based on custom technical drawings?
Yes. We specialize in deep processing such as precision cutting, burning mouth, pinching, bending, and laser engraving based on your provided CAD drawings or engineering files.
