Manufacturing:
When we remove the final custom manhole cover the process is called unmolding. With sand casting, unmolding is known as “shakeout.” This is done on a vibration table that assertively shakes as unflasked molds are dropped onto it. The shaking dislodges the sand which drops from the casting and sifts through holes in the table. The sand usually falls into a box or onto a conveyor, to be recaptured as molding sand.
REMOVING SAND CORES
Sand cores are made with resin or another substance that provides greater structure than basic foundry sand, and because of this they may need more than the vibrating table to remove them.
Machining
Sand casting often leads to a non smooth surface. If an item needs to be smooth, or needs precise dimensional tolerances, then it will be machined to match the exact product specs. Any additional grinding, slathing or lawing will also be done in accordance to pattern.
