At GIFA 2019, we unveiled our latest innovation, the 100% electric core shooter (E-shooter) is designed to deliver green core making. The e-shooter is environmentally friendly, more efficient and has the advantage of being Industry 4.0 compatible.
Advantages of an electric core maker
In addition to being a more environmentally friendly solution and improving the quality of your foundry's cores the electric core shooter offers the following advantages:
- Oil-free hydraulics
- No pit or foundations required
- No core box movement during shooting and gassing
- 30% energy saving
- Clean and silent
- Predictive and straightforward maintenance
- Industry 4.0 ready
Operational costs are significantly lower thanks to the energy savings, removal of insurance fees and reduced maintenance staff, when compared to conventional machines. The design of the core making machine ensures a completely closed core box without movement during shooting and gassing.
Key e-shooter performance figures
|Cycle time*||16 seconds|
|Number of production cycles||98 per hour|
|Estimated number of cycles**||2,058 per day|
|Total cores produced***||10,290 per day|
|Viable cores produced****||10,080 per day|
** based on estimated process cycle of 20 sec.
***based on 5 cavities core box
****based on 2% cores' scrap
Indradrive energy benefit in the e-shooter
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 31% less cooling power whilst reducing noise in operation. 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.
How a 100% electric core maker could help your foundry
Industry 4.0 is already 10 years old and yet many foundries have yet to take steps to become 4.0 compatible. The E-shooter brings economies in terms of energy performance and is a fully connected machine that integrates into a 4.0 infrastructure.
Downtime always has a negative impact on foundries and the E-shooter, thanks to its closed core box, has significantly less wear compared to a traditional shooter and simplifies maintenance. This means you can run more efficient cycles and increase your productivity.
