AI-Powered supplier vetting

SummaryThe supplier is a limited company offering optical lenses, sapphire lenses, sapphire glass, and watch lenses, with registered activities covering optical glass, functional glass, new optical materials, and related manufacturing. It reports a 1,500 m² manufacturing plant, five production lines, and equipment including CNC, grinding, molding, inspection, cleaning, and testing machinery. Customization from samples and designs is available. The supplier has in-stock capability and accepts FOB, CIF, CFR, and EXW terms, but has no overseas warehouse, showroom, agents, branches, or offline trade-show participation. R&D resources appear limited to two years of engineer experience, and no SDK is available. Certification status, customer cases, environmental documentation, fire-drill status, ERP integration, and sustainable-practice implementation are not sufficiently evidenced. A valid manufacturing-capacity contract with related subcontractors is explicitly absent.

Supplier typeThe supplier is identified as a limited company with a combined company type. Its stated activities include optical glass manufacturing, unsealed glass casings, non-metallic mineral products, jewelry manufacturing, and related optical-material sales, indicating a manufacturer with trading-related scope rather than a purely trading entity.

R&D capabilityThe supplier’s scope includes new-materials technology R&D and new optical materials, and it offers customization with listed production and testing equipment. However, no SDK is available, R&D engineer experience is listed as two years, and ERP and sustainable-practice implementation statuses are unknown, so overall innovation strength is mixed and not sufficiently established.

Production capacityProduction evidence includes a 1,500 m² plant, five production lines, optical and glass manufacturing scope, and equipment such as CNC, grinding, molding, ultrasonic cleaning, inspection, and impact-testing machines. In-stock capability is available, although the supplier explicitly lacks a valid manufacturing-capacity contract with related subcontractors.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad stated customization coverage.

Product Q&A

Q:Is sapphire glass made from real natural sapphire?

No, it is synthetic sapphire crystal created by crystallizing aluminum oxide at high temperatures. It has identical physical properties to natural sapphire but is manmade.

Q:Why is sapphire glass more expensive than standard glass?

The complex manufacturing process makes it costlier, but it offers unparalleled scratch resistance and durability, saving long-term costs from frequent replacements.

Q:What is the primary advantage of sapphire glass?

Its core advantage is Mohs hardness of 9, making it highly scratch-resistant. It also offers excellent optical transmittance and strong antireflective properties.

Q:Is sapphire glass shatterproof and impact-resistant?

No. High hardness does not equal high impact resistance. It can be brittle and susceptible to cracking under sharp, concentrated point impacts. It is best for scratch prevention.

Q:What are the available coating options?

Options include Anti-Reflection (AR) coating to reduce reflection losses, High Reflection (HR) coating for laser cavities, and Oleophobic/Hydrophobic coatings for anti-fingerprint protection.
