BEIJING, CHINA – Jovvi (Beijing Hengtai Tech Co., Ltd.), a global leader in radiation and electromagnetic shielding solutions, has announced the successful completion of a major upgrade to the internal structure of its medical radiation protection lead doors. The project, led by Jovvi's expert engineering team, enhances the doors' structural integrity, shielding performance, and operational reliability—demonstrating the company's technical professionalism and the superior quality of Jovvi's materials.
Engineering Excellence in Structural Design
The upgrade focused on re-engineering the internal framework of Jovvi's lead-protected doors, which are widely used in X-ray rooms, CT suites, DSA rooms, and nuclear medicine facilities. Jovvi's engineering team redesigned the internal steel skeleton structure, adopting advanced welding techniques and precision assembly processes to ensure unparalleled stability and durability.
Key structural improvements include:
Reinforced Internal Framework: The upgraded doors feature a steel skeleton with a solid thickness of ≥2.0mm, utilizing advanced welding processes to prevent deformation and maintain long-term structural integrity.
Precision Sealing Technology: The team implemented enhanced lead lining integration within the door frame, with lead sheet purity reaching ≥99.996%, ensuring zero radiation leakage around door edges and hinges.
High-Performance Door Axle System: The doors now incorporate stainless steel top-pin door axles with HK1816 bearings and anti-detachment design, capable of bearing loads ≥1.5 tons, ensuring smooth and secure operation over extended use.
Seamless Composite Bonding: The new design eliminates traditional screw fixation methods, adopting integrated bonding technology that combines decorative layers, shielding layers, and the steel skeleton without wood or screw holes—preventing damage to the protective lead layer.
Premium-Grade Materials Delivering Superior Protection
The success of the structural upgrade is underpinned by Jovvi's unwavering commitment to material quality. The lead doors utilize high-purity lead sheets with verified purity levels meeting or exceeding 99.99%, ensuring consistent shielding effectiveness across the entire door surface.
Material quality highlights include:
High-Purity Lead Shielding: The internal lead lining is manufactured through a rigorous rolling process, delivering a void-free, seamless protective layer that meets or exceeds national standards for X-ray and gamma-ray protection.
Corrosion-Resistant Surface Materials: Door panels are constructed from ≥0.8mm stainless steel or electrostatic powder-coated steel, offering excellent durability and resistance to hospital-grade disinfectants and environmental stress.
Anti-Microbial Hardware: Stainless steel locks and handles with antibacterial, anti-fingerprint finishes ensure hygiene compliance in medical environments.
Intelligent Control and Safety Integration
Beyond structural and material enhancements, the upgraded lead doors integrate advanced automation features that reflect Jovvi's commitment to user safety and operational efficiency:
Intelligent Control Systems: Microprocessor-controlled automatic door operators with brushless DC motors provide adjustable opening/closing speeds (250–500mm/s) and obstruction-sensing reverse functionality, ensuring patient and staff safety.
Infrared and Mechanical Safety Protections: Multi-layered safety systems, including infrared sensors, manual control redundancy, and mechanical anti-pinch mechanisms, guarantee reliable operation even in emergency scenarios.
Door-Light Interlock: Integrated with LED operational status indicators and ionization radiation warning signs, the system provides clear visual alerts to prevent accidental exposure.
Third-Party Verified Performance
All upgraded lead doors undergo rigorous third-party testing to verify compliance with national and international radiation protection standards, including GB18871-2002, GBZ130-2002, and GBZ/T147-2002. Field testing confirms that the doors achieve shielding effectiveness exceeding 96%, ensuring that radiation dose rates in controlled areas remain well below regulatory limits.
A Testament to Jovvi's Professionalism
The successful completion of this internal structure upgrade reflects Jovvi's engineering expertise and dedication to continuous improvement. By combining precision engineering with premium materials, Jovvi continues to set the standard for medical radiation protection solutions worldwide.
"At Jovvi, we believe that excellence in radiation protection begins with meticulous structural design and uncompromising material quality," a Jovvi engineering lead commented.
