LLT has established a sophisticated technical ecosystem organized into four specialized divisions that form the core of our innovation capabilities: the Connector Electrical Contact Research & Structural Design Department, the UL/TUV Certified Performance Verification Laboratory, the Precision Connector Manufacturing Workshop, and the Advanced Wire Assembly Division.
This vertically integrated structure enables continuous innovation in both materials and design methodology, ensuring seamless transition from concept to production while maintaining rigorous quality standards across all product lines.
Our specialized R&D center focuses on advanced electrical contact physics and structural engineering. The team employs computational simulation and rapid prototyping to develop next-generation connector architectures with superior mechanical integrity and signal integrity characteristics.
Our in-house verification laboratory operates to ISO/IEC 17025 standards with comprehensive testing capabilities for environmental simulation, mechanical durability, and electrical performance. This facility enables rapid certification pathways for new products while maintaining continuous quality monitoring for production lines.
Featuring over 30 precision injection molding systems and advanced metalworking equipment, our connector production facility maintains micron-level tolerances across high-volume manufacturing operations. Automated assembly and real-time quality monitoring ensure consistent product integrity.
Our specialized connector wire soldering workshop combines precision automation with skilled craftsmanship to deliver consistently reliable electrical connections. Advanced potting technologies provide enhanced environmental protection for the most demanding application scenarios.
Empowered by 200+ national patents, LLT has established a comprehensive product matrix of IP65~IP68+ sealing cable connection technologies for all scenarios. Our products feature ultra-wide temperature resistance, 20G mechanical shock tolerance, and deep-sea grade anti-corrosion protection systems, conforming to UL2238 and CE+TUV international certification standards.
