Hydraulic brick machine can produce many varieties and specifications of hollow brick, solid brick, blind hole brick, square brick, road paving brick and other new building materials products. The new technology adopts the control mode of internal displacement sensor, which is not affected by atmospheric environmental pollution, and can accurately ensure the external dimensions of various sizes of bricks. The machine adopts mechanical, electrical and hydraulic integration technology to make each cycle process of equipment operation consistent, so the stability of formed products is high and the scrap rate is low.
