Description

Technical Field

[0001] The utility model relates to the field of welding machines, in particular to a servo hot plate welding machine. Background Art

[0002] A hot plate welder utilizes the principle of electrothermal melting to weld plastics. It's suitable for thermoplastic materials like PP and PE, and is particularly well-suited for welding large and specialized plastic workpieces. During welding, a heating plate is placed between two plastic parts. When the workpieces are pressed against the plate, the plastic begins to melt. After a predetermined heating time, the plastic on the workpiece surfaces reaches a certain degree of melting. At this point, the workpieces separate, the heating plate is removed, and the two pieces are brought together. The welding process is complete after a predetermined welding time and depth have been reached.
