Quality Assurance & Testing
EDXRF spectrometers provide rapid, non-destructive elemental analysis for various materials. They are widely used for quality control and material verification, delivering accurate compositional measurements and impurity detection. The system supports environmental compliance testing such as RoHS certification, and can analyze plastic components, copper contacts, and metal oxide content in our products, ensuring that raw materials meet environmental protection and quality standards.
Automated Manufacturing Process
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.
