Pneumatic cylinders and copper parts are widely applied in clamping, positioning, pressing, and feeding operations. Pneumatic cylinders provide stable pneumatic motion, enabling precise reciprocating movement and pressure control at welding stations. Copper parts, with excellent electrical and thermal conductivity, are used for welding electrodes, terminals, and conductive blocks to ensure efficient and reliable current transmission. The optimized combination of these components improves welding quality, enhances productivity, and extends equipment service life, making them suitable for spot welding machines, butt welding machines, and seam welding machines.
