The mold is a basic equipment to make blocks. The production capacity depends on the amount of the mold. The combination of the bottom of the mold and the wall of the mold is flexible. For example, you can produce 100 cubes of bricks by using 50 walls and 100 bottoms. So you can decrease the investment by buying more bottom and less wall. One can also save the cost by using the cement floor as the bottom of the mold.
