Bench type pneumatic welders

The bench welders have a worktop for positioning the support piece holder and rigid perpendicular structure, on which a shelf slides to carry the motor with the piece holder spindle. The shelf is driven by pneumatic cylinder. The electrical and pneumatic control part can be housed inside the machine structure or contained in a separate unit.


The SWP 06 spin welder was designed and manufactured using state-of-the-art technologies (3D CAD, CNC). With this technology, most thermoplastic materials having a round shape can be welded.
For spin welding technology, the heat needed to melt the parts is produced by a rotating motion combined with thrust pressure. One of the parts to be welded is held by a fixture, while the other one is set in motion by a rotating spindle. The assembly process is easy and based on easily understood, well-known principles of physics. Welding joints are simple and permit a high degree of design freedom. The tools that hold the pieces to be welded are also simple and can be made by the client. The mechanical and electric solutions available create optimal working conditions with ample adjustment possibilities, making the welder ideal for most welding applications.
The welder has a highly robust structure. The motor that drives the rotating spindle is the brushless type. Movement of the transducer holder head is pneumatic, controlled by a proportional valve and takes place on high precision prismatic guides with excellent mechanical features.
