x ray glass factory

When sourcing from an X-ray glass factory, the most critical factor is the Lead Equivalent (Pb value), typically ranging from 0.5mmPb to 4.0mmPb depending on the radiation energy (kV) of the equipment. You must also verify the Light Transmittance, which should be above 85% to ensure clear visibility for medical staff, and the Density, usually exceeding 4.36g/cm³ for high-shielding performance.

Professional buyers must ensure the factory adheres to IEC 61331-2:2014 (Protective devices against diagnostic medical X-radiation). For the US market, FDA registration is essential, while the European market requires CE Marking and compliance with the Medical Device Regulation (MDR). Always request a Radiation Protection Test Report from a third-party laboratory.

Check for surface bubbles, inclusions, or scratches, as these can impair visibility and indicate poor manufacturing processes. High-quality X-ray glass should have excellent chemical stability to prevent 'fogging' or oxidation over time. Ask the factory if they use automated polishing lines to ensure a thickness tolerance of ±0.5mm.

ZF2 or ZF3 series high-lead glass is standard for X-ray rooms, CT scan rooms, and PET-CT suites. For industrial applications like Non-Destructive Testing (NDT) or nuclear power plants, thicker glass with higher lead content is required. Ensure the factory provides custom cutting services to fit specific observation window frames.

The biggest risk is physical breakage due to the high density and brittleness of lead glass. You must mandate vacuum-sealed packaging and reinforced fumigated wooden crates with shock-absorbing materials. It is highly recommended to use Made-in-China.com's Secured Trading services to protect your payment until the goods arrive intact.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for tiered pricing based on annual volume and request a warranty of at least 5 years against discoloration or spontaneous cracking. For large projects, ask for Incoterms 2020 DDP or CIF quotes to simplify the complex logistics of heavy, fragile cargo.

Always conduct a Factory Audit or use the Verified Supplier reports available on Made-in-China.com to confirm the manufacturer's production capacity. Never transfer full payment upfront; use a 30% deposit and 70% balance against the Bill of Lading (B/L) after a successful pre-shipment inspection.

Ensure the factory provides the correct HS Code (typically 7013 or 7003 series) and a detailed Packing List. Because this is a medical-related product, some countries require a Certificate of Origin and a Radiation Safety Declaration to avoid delays at the border. Verify if your local customs requires a Medical Device Import License before the cargo departs.
