Exceeding Customer Expectations - Ceramic Nozzle

Exceeding Customer Expectations - Ceramic Nozzle

Our customer pursued electro-formed gold, believing it was their only option, But partnering with SPT resulted in a CIM zirconia nozzle that outperforms the gold nozzle in all aspects

  • Full component characterization, including flow testing.
  • OD: +/- 0.003mm
  • Orifice:
    Size 0.070 +/- 0.0025mm
    Concentric < 0.010mm
    Circularity < 0.0025mm
Process Stability

Process Stability

  • Optimizing production processes to guarantee for the most process stability.
  • Developing and building atomatic production machines, handling systems and inspection systems for the parts. 
  • Engineering of special fixtures and gauges for our production.
