Manufacturing of Bricks for Masonry Construction – Methods and Process
The mold is then lifted up and we have raw brick in the ground. And again wet the mold by dipping it in water and repeat the same process. The process of dipping mold every time to make bricks is called slop molding. Sometimes, the inside surface of mold is sprinkled with sand or ash instead of dipping in water this is called sand molding
