3D Spray Heads

Proven technology taken one step further

Closed-die forging presses are used, for example, in the automotive industry. The spray head removes scale from the dies, cools the die surface, applies lubricants and dries the dies. SMS group now goes a step further with the new, additive-manufactured 3D spray heads:  The external-mix two-fluid nozzles produce an extremely fine aerosol. Unmixing, as in internal-mix systems, naturally cannot occur with this technology. The homogeneous, constant-over-time spray pattern provides for a long tool service life and optimal spraying results. The nozzles can be switched individually or in zones and offset in time. To switch the nozzles, SMS group continues to use the tried and proven membrane material for the 3D spray heads. The membrane platelets are located directly at the nozzle. The short switching periods allow for high dynamics, while dripping is precluded.

New possibilities bring an innovation push

Apart from these advantages, the new 3D-printed spray heads offer even more benefits:

  • Lightweight design and low structure height
  • Spatial nozzle arrangement customized to the client
  • Low installation and maintenance costs
  • Leak-free system in one-part construction
  • Flow-optimized form to prevent deposits in the canals
  • Prevention of spray medium collection on the spray head
  • Homogeneous spray pattern due to demand-oriented design and free arrangement of the individual nozzles, also at an angle
  • Operating pressure of between three and ten bar can be used
  • Fast acquisition due to automated construction
