The maximum shot weight depends on :
- material being used.
- volume of barrel (cm3).
Different material - different gravity under temperature.
How to calculate max. shot weight :
= volume . factor
(cm3) . (g/cm3)
For example :
Volume of KM achine 120-460 with screw diameter = 275 cm3
Max. shot weight for ABS = 275 . 0.90 = 247 g
This means max. use of screw stroke !
As a recommendation from KM machine : do not use the screw stroke more than 85 - 95%
