For our welded assemblies, SHZHJ leverages advanced process control and strict quality standards to ensure every weld point delivers excellent electrical and mechanical performance. Whether applied in switches, relays, or other conductive systems, our welded assemblies achieve low contact resistance and high tensile strength. By optimizing welding parameters and material matching, we effectively avoid common issues such as cold solder joints, porosity, or overheating failures. Each batch undergoes systematic reliability testing, guaranteeing stable performance even under prolonged power exposure or frequent switching cycles. SHZHJ’s welding solutions not only enhance the safety of end products but also significantly reduce on-site maintenance costs.

For riveted components, SHZHJ provides a complete manufacturing capability ranging from composite contact rivets to various precision riveted elements. Our composite rivets are produced using high-precision forming processes, achieving a silver-to-copper bonding strength exceeding 150MPa—twice that of traditional methods—completely eliminating the risk of silver layer edge lifting or delamination. Meanwhile, the CPK (Process Capability Index) for critical dimensions is consistently above 1.33, reaching 1.67 for single batches. This means you won’t need to frequently adjust your automated riveting equipment. Whether you require standard round or flat shapes, or complex custom profiles like stepped or asymmetrical designs, SHZHJ maintains strict tolerance control, helping you simplify your supply chain and improve assembly yield.
