The extrudate shape, dimension and output can be effectively controlled on single roller extruder with its variable screw and roller speeds and the flexible combination of preform die and final die.
Small part dimension and tolerance? Low weight? Adaptation of machine performance to the parts? Flexible machine configuration (many molds suitable for one machine)? Stable quality, reproducibility.
The geometry of the flexible cantilever based one dimension compliant mechanism is optimized to get the biggest output displacement by using orthogonal arrays and analysis variance.
