This part consists of two SPHC stamped pieces (2.3mm thick) joined by a pivot pin, requiring high concentricity and precision between the holes for smooth, snag-free rotation.
The bending/forming step must ensure the press direction and folded edges are free of scratches or dimensional deviation, since this component bears the patient’s load during bed rotation/folding movement.
The pin welding process also requires strict control to prevent weld spatter from landing on the surface, as both safety and appearance quality are critical for a medical device component.
