From a circular economy perspective, the recovery and reuse of waste plays a fundamental role. Foundries purchase hundreds of millions of siliceous sands every year to create molds and cores that give shape to the casting. These sands, after several uses, become waste that must be properly recovered or disposed of; they are called waste …

If the shear strength of the sand is below that of the pressure created by the liquid metal filling the mold, the core might split and create a distortion in the casting body. Binders are a big part of the core-sand making process. Green sand cores are made from standard damp molding-sand mixtures, and a binder, like dextrin. Cores of this type ...

Because the amount of cores can vary from job to job, using core sand as new sand additions can be a hit-or-miss method unless it is separated from the green sand, and then metered back in at a given rate. The second source of airborne silica dust is the sand still attached to the castings after shakeout (in pockets, cavities, and corners.)
YouTube creator The King of Random demonstrates aluminum casting in this short video of his at-home Mini Metal Foundry.

Steps for taking permeability test. Step 1: Green sand is rammed under the sand rammer to prepare the sand specimens. A 5cm x 5cm standard specimen of sand is used. Step 2: The sand specimen is held by a tube called "sand specimen tube." This standard specimen has Height =H in cm and Area = A in cm².
Lost offers design, cost, and environmental advantages such as no cores, core defects, or core fins. Dry unbonded sand is used so there is no moisture or binder related defects. This simple process control allows for lower labor costs, lower capital costs, lower machine tooling damage, and lower energy consumption.
