Usually Stored In A Hopper, The Core Sand Is First Transported And Treated In The Preparation System, Where A Heavy-Duty Mixer Ensures Optimum Blending And Homogeneity Of The Core Sand. The Preparation System Also Includes An Automatic Binders Dosing Device, That Injects Both Agents On A Timed System To Help Increase The Rigidity Of The Cores.Once treated and mixed correctly, the core sand enters the discharge chute via a pneumatic vibrator tray and enters a vertical hopper, situated above the core shooter.
The core shooting machine will be used to make gassing cold box cores in horizontal parted core boxes. The shooting volume is approx. 40 dm³, however, the shooting volume can be increased by double shooting.
Once the hopper is full of sand mixture, the front entrance will shut, and the lower section and upper section of the shooting machine form the core shape. These sections are then compressed against the gassing unit and a seal is created ready for the core to be created. Once in position and a seal has been created, the shoot machine will blow compressed air and the sand will enter the core box.
cold box core shooter method
Now the core box has been created the gassing stage occurs, hardening the sand core box. This is where the cold box process receives its name, instead of using massive amounts of heat to harden a core, gas is used as a catalyst to rapidly harden the sand. The gas used is Triethylamine and it is a hazardous gas, hence why all operators are recommended to wear respirators.
Once the process has finished, an ejection system will remove the cores for inspection by the machine operator, prior to storage and finally production.
In the cold-box method for creating sand cores, a resin coated sand is blown into a room-temperature box which is sealed, and a gas catalyst is then passed through holes in the pattern to harden the core. Amine Gas is used to cure the core instantly to a relatively strong state.This is the most effective method for mass production of cores.

Why Sand Core Systems Are Widely Used
Choose the plan that suits you best.
Create Complex Internal Shapes
Cores allow foundries to make hollow spaces inside castings (like engine cooling channels or pipe cavities).
Without cores, you'd only get solid blocks of metal!
Design Flexibility
Almost any shape can be made by using different sand core designs - thin walls, curves, pockets, tunnels, etc.
Supports complex castings like engine blocks, pumps, valves, manifolds, and machinery parts.
Cost-Effective
Making sand cores is much cheaper than trying to machine hollow spaces after casting.
Saves time, material, and tooling costs.
Fast Production
Modern core shooters (Hot Box, Cold Box, Shell Core) produce high volumes of cores quickly and consistently.
Helps foundries keep up with high production demands.
