Roberts Sinto's SCC Core Center revolutionizes core production. The SCC Core Center uses the most advanced technology in core machine processing to produce intricate cores from a few ounces up to 130 lbs.
Controls:
- PLC Controls
- Touch Screen
- Diagnostics
- Linear Transducers
The SCC Core Center controls allow the complete operation, set-up and machine monitoring from a single touch screen control mounted on the front of the enclosure. All major operations are hydraulic and are controlled by linear transducers providing fast, accurate operation.
Continuous Clamping of Core Box
The SCC Core Center continuously clamps the core boxes during the core making process. The blow head and gassing head are moved to the core box, keeping the mechanism simple and reducing the possibility of finning.
Special Air Flow Fluidizing Blow Chamber
The special blow chamber fluidizes the sand allowing the operator to make high-density intricate cores. The SCC Core Center will blow cores from a few ounces up to 130 lbs.
Horizontal / Vertical Core Boxes with Quick Change
The SCC Core Center can use both horizontal and vertical core boxes. A vacuum clamping system allows the SCC Core Center to use existing tooling and simplifies set-up.
Total Self-Contained System
The SCC Core Center is a complete system including mixer and gas generator, all contained in an environmentally friendly system

During the last years Belloi & Romagnoli has developed, together with the above-mentioned multi-piston technology, also the moulding principle based on air impact + high pressure. This choice has been made in order to make a modern and cost-effective technology available to all foundries, also to smallest ones.
The B&R COMPACT 4 moulding machine was designed for foundries that require high quality moulds at low-medium production rates. This machine will provide better quality and faster production rates than the typical jolt squeeze moulding machine. The machine uses air impact and a hydraulic squeeze to make the mould. The moulding media for this machine is green sand.

Moulding is the operation that allows to give shape to green sand in order to obtain impressions as equal as possible to the pattern.
This is one of the most important functions of the production process and deserves a particular attention both from a technical point of view (selection of the type of moulding) and from the point of view of the customization of the plant.
