Precision Manufacturing for Superior Connector Performance

Our production facility features dozens of advanced automated injection molding machines with precision tolerances of ±0.01mm, ensuring consistent product accuracy and stability. The insert housing utilizes integrated die-casting technology to maintain structural integrity and dimensional precision. This manufacturing excellence guarantees reliable component fit and long-term durability, enabling our heavy-duty connectors to perform flawlessly in the most demanding industrial environments.

Automated Insert Assembly for Precision Performance

Our heavy-duty connector production integrates an automatic core assembly line, manufacturing from the inside out. First, silver-plated contact pins are automatically assembled for reliable electrical connections. Next, dual-row screws are installed via automation, followed by the precise assembly of surrounding copper components. The process delivers fully integrated, high-precision connectors with consistent quality and superior performance.
