Precision & Repeatability

The new system is both low cost and simple enough to be viable on small engines from 50 to 250cc, a range that covers everything from lawnmowers and small marine outboard motors to motorcycles and scooters.

The rig used by Scion Sprays to hold the components in place during laser-welding uses a Kistler NCFT servo press module. These modules are simple to install requiring only a 3-phase electrical supply and have integral piezoelectric force and absolute encoder displacement monitoring capabilities that simplify the precise programming of home position, return stroke, joining stroke and an intermediate position. Of special importance to Scion Sprays is the 0.005 mm repeatability of the NCFT units under real world, production conditions ensuring that the injector pulse volume of 1μl (one micro litre) is maintained during quantity production.
