The principle of hot plate welders is simple and intuitive. Thermoplastic materials, by definition, are sensitive to heat and the materials melt by direct contact with a hot plate with electronic temperature control.
The hot plate welding principle is simple and intuitive.
Thermoplastic materials are by their very nature heat sensitive. Using this technology material melting occurs as the result of direct contact with an heated plate whose temperature is controlled electronically. The pressure applied during the welding of thermoplastic materials is one of the essential parameters, as well as correct temperature setting which should be of between 250 e 350° C.
The two parts to be assembled are contained inside the relative fixturings and the hot plate welding cycle occurs automatically controlled by the settings of the heating and cooling times.
The mechanical movements of the machine must be fast, so that the heating and the melting of the weld joint, is sufficiently plastic for the interpenetration of the two parts to be welded.
The equipment is fitted with mechanical stops that determine the melting and packing height values of the parts to be assembled.
