01 / Spin Welding

The welding of thermoplastic materials using spin welding occurs as the result of the melting of the contact surfaces.
The increase in the local temperature necessary for the melting  process is obtained through the rubbing of one of the two pieces to be welded. The rotating part is subjected to a thrust pressure so as maintain contact between the parts during the process.
In these spin welders, the rotary movement is generated by means of specially controlled motor and with a spindle which has the shape of the part to be welded.

This technology makes it possible to weld parts made of thermoplastic material with round shape only.

Areas of
Application
Filters
The spin welding allows to assemble articles of exclusively circular shape. This is the case with water filters and fuel filters.
Technical articles
Thanks to the use of rotational technology it is possible to weld pieces made in most thermoplastic materials and with exclusively circular geometric shapes.                                                                                                APPLICATION EXAMPLES: welding of filtering elements, welding of valve bodies.
