Indexed spin welding machine for plastic

All thermoplastics as well as elastomeric are weldable if they can be count in the group of GF-materials and filled materials.
Good weldable thermoplastics are: ABS,PA,PC,PMMA,POM,PP,PS,PVC,PVC-U,SAN, and their reinforced modifications.
We consider basic-welding for new materials suggestive, these can with the help of test-plates be welded in the standard sizes of 50 x 40 mm and they reduce the expense considerable compared to the part of the mould-sample which at least makes a simple acceptance-tool necessary.
Thin wall parts and thin joint-flanges are ideal to connect.
The welding oscillation operates to all sides also in the direction of the thin wall part and transverse of it. Due to these rotating oscillations the walls remain thin and instable against the friction strength in its position.
Wall reinforcements are only necessary at instable work-pieces.
The welding flow of the melt is reduced due to the circular welding kinematics but not removed. A small visible welding flow is the proof for the root-penetration in the joint connection.
QUALITY DEMANDS TO THE ASSEMBLY-PARTS
Good welding connections can be achieved with parts which are according to the geometry of the parts adapted joining zone and shaped for the friction welding. No special seam-shaping is necessary for circular-welding if the shaping is constructed to RS.
Equal vibrations to all sides are allowed, even smaller welding flanges and therefore exact welding at precision-parts.
