Description

The JML e-shooter is a fully connected and 100% electric Industry 4.0 compatible machine. Operational costs are significantly lower thanks to the energy savings, removal of insurance fees and reduced maintenance staff, when compared to conventional machines.

The E-Shooter is based on a lower static structure and movable shooting and gassing head. The design of the machine allows a better access for maintenance and cleaning. The absence of the shooting cartridge reduces the time for cleaning.

-30% energy saving

2,397 kWh/a are saved using the 4EE solution. This can amount to 383 €/a of savings (404g/kWh, 0.16 €/kWh) and a carbon dioxide reduction of 1 t/a.

E-shooter performance

  • 16-second cycle time (based on split core boxes)
  • 98% machine efficiency
  • 98 production cycles per hour
  • 2,058 estimated cycles per day (based on a cycle process of 20 secs)
  • 10,290 total cores produced per day (based on 5 cavities core box)
  • 10,080 viable cores produced per day (based on 2% cores’ scrap)

Indradrive energy benefit

The E-shooter uses a Rexroth 4EE electric solution. When compared to a standard hydraulic power unit with vane pump for pressure supply, this machine requires less cooling power and reduces noise when in operation.
