Hot Plate Welding Machine

Hot Plate Welding is a thermal welding technique capable of producing string, air-tight welds in thermoplastic parts. When using thermal energy in a tightly controlled manner, thermoplastic parts can be heated to molten.�We provide our clients with a quality range of hot plate plastic welders which are used in automobile industry, FCMG industry, plastic industry and others. These products are known for their reliable & safe operation, low maintenance, cost-effectiveness, superior efficiency and high quality. Hot plate welding is the most appropriate method to join large size parts even with complex shapes. After cooling, the weld is aesthetically pleasing, leak proof, and characterised by its strong joining force. To a certain extent, hot plate welding allows to join elements having some degree of dimensional tolerance.It is possible to weld all kind of thermoplastics, even if they come with different stiffnesses. When needed, a double weld bead could be used to duplicate the welding feat. Process: Part halves are placed into and securely gripped by precision holding fixtures which insure adequate support and accurate alignment of the part halves throughout the hot plate welding process. To heat the part joint area, a thermally heated platen is placed between the part halves. The holding fixtures close to compress and melt the part halves to be welded against the platen, displacing material at the joint area only. Compression and material displacement continue until precision hard-stops built into the tooling are met. Thermal heat continues to conduct into the material even though compression and displacement have stopped. After the joint area reaches molten temperature, the holding fixtures open and the heat platen is withdrawn. The holding fixtures then close, forcing the two parts together until hard-stops on the holding fixtures come into contact with one another. When cooling is complete, the gripping mechanism in one of the holding fixtures releases the part, the holding fixtures open and the finished part may be removed. Feature: Touch panel human machine interface for quick setup and user friendly operation Interlocked safety doors with full guarding provide maximum operator safety Imported special steel heat plates, welding beautiful, can use very long time All imported pneumatic components, quick to respond to sensitive and improve work efficiency Digital temperature controllers for precise temperature control over entire platen Popular used in automotive and household electrical appliances industry Can choose pneumatic, hydraulic or servo motor drive manner
