FEATURES OF PLASTIC:

  • Can be used for prototypes, functional models or lost models
  • Fast delivery within a few working days
  • Precise layering of 80 / 120 / 150 µm
  • Components of any complexity
  • Economical production in batch sizes of 1 as well as in series production
  • Infiltration in any color
  • Wax-infiltrated parts for perfect investment casting result

 

FEATURES SAND:

  • 100% inorganic binder
  • Good bending strength
  • Castable with all alloys
  • Relatively low emissions during casting
  • Emissions are mainly water
  • Low running costs
  • Process operates at room temperature
  • The sand mixture comes ready to use
