The upper and lower hot plates employ multi-zone independent temperature control and can be designed to conform to the workpiece contour, compensating for uneven heat absorption caused by structural differences and ensuring consistent melting depth across the entire welding surface.

The hot plate surface is coated with a Teflon or other non-stick coating, and the demolding stroke and speed are optimized to effectively prevent workpiece stringing or deformation, thereby improving product yield and appearance quality.

A laser displacement sensor is used to monitor the melting depth in real time to ensure batch consistency.With the quick-change mold system, production line changes can be completed in minutes, adapting to flexible production needs.
