The hot plate welding machine mainly uses a temperature-controlled heating plate to weld plastic parts. When welding, the heating plate is placed between the two plastic parts. When the workpiece approaches the heating plate, the plastic begins to melt. After the preset heating time, the plastic on the surface of the workpiece will melt to a certain degree. At this time, the workpieces are separated from each other, and the heating plate is removed. Then combine the two parts-together. When the hot plate stops working, let the pressure continue for a few seconds to solidify. In this way, a strong molecular chain is formed, the purpose of welding is achieved, the welding strength can be increased beyond the strength of the raw material, and the entire welding process is completed.

Hot plate welding machine welding steps:

(1): Reset state: When the equipment is in the stop state or start state of a working cycle, and the entire working cycle is in the automatic state, manually put the plastic parts to be welded into the upper and lower molds (the mold is equipped with a vacuum suction cup for (Holding device for plastic parts)

(2) When the upper and lower plates are in hot pressing state, the upper and lower plates are in thermal contact, and the welding surface of the plastic parts to be welded is hot melt

(3) Hot melt state of plastic parts: The upper and lower plastic parts have been melted and cannot be carbonized within the specified fusion time

(4) When the welding time is up and the upper and lower molds are safe, the upper and lower plastic parts are at the same time away from the hot plate for a certain distance, and then the hot plate exits to the exit position

(5): The upper and lower rubber parts are closed under the action of the upper and lower cylinders. In the preset curing time, the two rubber blocks are fused into one block. After the welding is completed, the upper vacuum sucker loosens the upper cover of the plastic part. The upper and lower templates are reset to the state (1), and the lower vacuum chuck is released. The welded rubber parts are manually taken out, and the machine waits for the next welding cycle.
