Thermoformed PVC Rigid Sheet welding methods are generally considered irreversible thermoplastic welding. A few processes such as induction welding can produce reversible assemblies. As for which method to choose, it should be made at the beginning of the workpiece design, because the welding method can be very important for the description of the workpiece, and different welding methods are not the same.
Hot gas welding techniques are generally used to weld Thermoformed PVC Rigid Sheets, sheets or semi-finished products rather than injection molded parts. However, many thermoplastic moldings, commonly thermoplastic automotive discs, are repaired using hot gas welding techniques, which are also sometimes used to make plastic-like moldings. Hot plate welding (for flat parts), it is a thermoplastic welding process that uses electric heating of metal molds to soften the surface of the joined plastic parts. Applicable to almost all thermoplastic parts large or small. Since different mold surface temperatures can be applied to two different thermoplastic materials, this process is suitable for welding different materials. Hot plate welding can achieve very high welding strength. However, the cycle of this process can be relatively long, 15s for small parts and several minutes for large parts. Hot gas welding is a welding method widely used to join thermoplastic profiles and sheets to produce very large parts. Suitable for smaller injection-molded parts that require some assembly, repair of thermoplastic parts and the manufacture of prototype parts. It is important to manufacture electrodes from the same polymer brand as the parts being welded.
Extrusion welding is a welding method developed from hot gas welding. Automatic welding for larger sheet size planning. Adhesives can be used to join plastic parts of the same material polymer, and are generally used to edge parts made of different materials. Join thermoset plastic parts to each other, or thermoformed PVC Rigid Sheet parts to metal.
