Plastic welding can be done using a hot plate. Several names exist for this process: heated mirror welding, mirror welding, hot plate welding, and hot blade welding.

This welding process is especially suitable for welding large plastic parts, parts with complex geometry or made of flexible materials. It is used to produce both technical and aesthetic assemblies.

It is contact welding: the plastic parts are in contact with the hot plate thus allowing the transmission of heat energy to the parts to be assembled.

When the material fusion point is reached, the hot plate is withdrawn. The plastic parts are then assembled together. This technology ensures non-removable assemblies, that can withstand high mechanical stresses, and ensures sealing.

Examples of welding by hot plate for thermoplastic parts: lights, tanks, filters, tubes, air distributors, toys, household appliances and more.
