Hot plate welding

Hot Plate Welders

The principle of hot plate welding is easy and direct.
Thermoplastic materials, according to the definition, are sensitive to heat. With this technology, the fusion of the material is achieved by direct contact with a heated and electronically thermo-regulated plate. The pressure exercised during the welding of the thermoplastic materials is one of the essential parameters, such as the correct temperature setting, which is between 250 and 350° C.
The two parts to be assembled are contained inside respective fixtures and the hot plate welding cycle is performed automatically, and is handled with the setting of the heating time and the cooling time.
The mechanical movements of the machine have to be quick, in the way that the heating and the fusion of the welding joint are sufficiently plastic for the interpenetration of the parts to be welded.
The toolings are equipped with mechanical locks which determine the fusion height and the solidification quote of the parts to be assembled.
With our hot plate welders, you can even weld parts having big dimensions which have as well to be watertight.
The sale of hot plate welders finds a lot of space within the assembling of parts made of semi-crystalline thermoplastic materials as polypropylene, with particular reference to household appliance and automotive field.

The sale of welders for thermoplastic materials within the hot plate welding field.
Applicative examples.

 Our production of hot plate welders provides two types of welders: the hot plate welder Basic series and the hot plate welder Linear series.
The Basic one stands out for easy use and the quality/price ratio.
It is unique in its kind as it is a bench-type one.
The Linear one is suitable for hot plate welding of parts with medium-big dimensions.
This machine may be endowed with an hydraulic unit to have a thrust pressure between the two parts that is especially high. We can manufacture special welding machines, capable to satisfy specific industrial requirements. Our technical service provides directly for the sale of spare parts for plastic welding machines.
