Screw vacuum pump housing

Pump housing EN-GJL-250

Initial situation at the customer

Screw vacuum pump chamber bore

  • Bottlenecks in project planning and process design due to large increases in lot sizes and a high degree of variation of parts
  • Massive problems due to fluctuations in casting quality and therefore reduced process reliability in the inventory process
  • Lack of qualified personnel for process supervision during series production

Special features of this solution

  • Regulation of casting fluctuations through precisely tuned progressive die
  • Optimal guiding and avoidance of vibrations during machining with difficult length/diameter ratios
  • Low cutting material costs thanks to insert solutions
  • Short cycle time and therefore maximum productivity thanks to multi-blade solutions
  • Cost savings through multiple usage of tools for parts families (20% savings)
