Innovations in Domestic Connector Technology: Stepping towards High Quality Gradually
In recent years, domestic connector manufacturing enterprises have made significant breakthroughs in the process level, gradually narrowing the gap with international brands through the introduction of precision mold processing, automated assembly, and quality control systems. In the in-depth comparison with brands such as ASSMANN WSW, domestic manufacturers have particularly achieved quality improvement in the following aspects:
Mold accuracy and automated assembly
The promotion of high-precision CNC machining and modular mold design has significantly improved the consistency of domestic connector shells and the precision of PIN foot arrangement; through automated pin insertion, welding, and packaging processes, it has greatly reduced human error and improved production efficiency and batch stability.
Material upgrade and electroplating treatment
Domestic brands are gradually aligning with international standards in material selection, using engineering plastics such as UL-certified PBT, PA9T, and LCP, to improve flame retardancy, heat resistance, and insulation properties; at the same time, through multi-layer gold plating, tin plating, and other treatments, significantly improve the contact resistance and service life of connectors.
3. Detection System and Reliability Verification
Drawing on the high-standard testing system adopted by ASSMANN WSW, domestic factories have introduced methods such as salt spray testing, high and low temperature cycling, and insertion and extraction durability tests to ensure the stability and reliability of connectors under harsh conditions.
Customization capabilities and response speed

Domestic manufacturers have significant advantages in localization engineering support, rapid prototype production, and customized services, especially in projects related to new energy, intelligent manufacturing, and rail transportation, where they can better synchronize with customer schedules and achieve fast matching from design to mass production delivery.
