Vibration welding is a newly developed welding technology. It can weld a wide variety of thermoplastic parts without implementation of additional connectors or self-consumable materials such as adhesives, solvents, etc., and only the plastic parts themselves are welded together by the welding process.
Almost all thermoplastic materials can be welded by vibration welding technology, whether they are injection molded, extruded, foamed, or thermoformed. This joining method is particularly advantageous for crystalline resins such as acetal, nylon, thermoplastic resins, polyethylene and polypropylene. Other materials, including cellulose, thermoplastic and synthetic rubbers, fillers, reinforced resins, and those materials with hygroscopic properties are also easily welded.
In any case, the two welded parts must be the same thermoplastic resin or compatible resin. Most thermoplastic resins are well welded to the same materials as themselves, but some different materials can be also welded together, for example: polycarbonate to polypropylene, ABS to polypropylene. However, in general, different materials cannot be well welded.
