AI-Powered supplier vetting
SummaryThe supplier is identified as a trading company with a stated 10,000-square-meter production base and multiple processing machines. It holds an ISO9001:2015 certificate, reports established complaint-handling and corrective-action procedures, and offers broad customization services. Export experience is stated as nine years, with exports representing 51%–70% of sales and markets including South America and Europe. Production quantities and peak-season fulfillment information are provided, but the supplier reports no new products in the past year, no ODM or SDK capability, no overseas agents, warehouses, showrooms, or inventory service. Financial information is incomplete and inconsistent across the supplied records, so financial credibility cannot be confirmed. No specific customer cases or named brand OEM experience are provided.
CertificationsThe supplier reports holding an ISO9001:2015 certificate. This is explicit evidence of a quality-management certification, but no additional certification details or validation information are provided.
After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaint handling. However, the quality-assurance status is unknown, so the evidence supports a positive service-process assessment but not a complete after-sales capability evaluation.
R&D capabilityThe supplier reports no new products during the past year, no ODM service, and no available SDK. These are explicit limitations in recent product innovation and development-related services.
Production capacityThe supplier describes a 10,000-square-meter production base with water-jet, CNC, milling, and other processing equipment, reports 6–10 quality-control staff, and lists production quantities for several product categories. It also states peak-season order fulfillment within 15 working days, providing explicit evidence of production resources and operational capacity.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. These services are reported consistently across the two records, indicating broad customization coverage.
Product Q&A
Q:What is the main difference between SK-1300 and traditional fused silica?
A:
SK-1300 is produced using the VAD process, providing much higher purity, lower OH content, and better UV transmission than conventional fused silica.
Q:Can SK-1300 be used for UV lithography applications?
A:
Yes. Its high UV transparency and low impurity levels make it ideal for photomask substrates and exposure optics.
Q:What are the available forms or dimensions?
A:
SK-1300 can be supplied as rods, plates, tubes, or custom-cut blanks according to customer requirements.
Q:Is it suitable for high-temperature use?
A:
Yes. It has excellent heat and mechanical resistance, making it stable even in high-temperature reactor environments.
Q:Can it be used for optical coating or polishing?
A:
Absolutely. The surface is stable and compatible with standard optical coating and polishing processes.
