Operation
A feature of NETCore® is that the breaker core utilizes a ceramic medium. The high refractoriness offers a significant advantage for preventing metal penetration and distortion, the improved breakdown of the core at shakeout ensures the formation of a clearly defined riser neck. NETCore® has a refractory fabric incorporated in the sinter-free breaker core and where placed, the mesh introduces a clearly defined fracture point within the riser neck, systematically weakening the material at approximately 80% of the cross-sectional area. At this predetermined breaking point, the riser rest can be removed quickly and safely through the formation of a breaking edge “0” at the casting surface.
Advantages of NetCore®
Efficient, precise
removal of risers in perfection
- Reduced cleaning costs
- Faster processing times
- Improved productivity
- Eliminates breaking into the component
- Improved casting surface
- Reduced mechanical load on the component
- Applicable for riser contact diameters up to 450 mm
- Improved process reliability and work safety
