PP plastic welding machine is a kind of plate we often use. It has low density, easy welding and processing, excellent chemical resistance, heat resistance and impact resistance, non-toxic and odorless. It is currently the most environmentally friendly engineering plastic. one. So do you know how to weld PP sheets, and what are the welding methods of PP sheets? The welding method of PP sheets is generally considered to be irreversible by the Hot melt plastic welding machine. A few processes such as induction welding can produce reversible assemblies.
As for which method to choose should be selected in the design of the part, because the welding method is very important for the description of the part, and different welding methods have different effects.
Hot Plate Plastic Welding Machines are generally used to weld plastic tubes, 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 Plastic Welding Machine is a thermoplastic welding process that uses electric heating of metal molds to soften the surface of joined plastic parts. Applicable to almost all thermoplastic parts large or small. Commonly suitable for welding softer semi-crystalline thermoplastics such as PE sheets or PP sheets. Since different mold surface temperatures can be applied to two different thermoplastic materials, this process is most 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.
