Brick made by the rotary table type brick machine is not in

What is the problem if the rotary table eight hole brick machine can not make standard brick size,such as the width of the brick on both side is not the same?

The answer is that it's the problem of the mould,because the mould  may be used for a long time, the friction level of the mould from height direction  is not the same. It is to say that the the friction level was gradually lengthened from feed direction to the direction of the product coming out. It causes the mold height facade bulk of the small head. So the bricks will have this kind of problem. New model will have no problem.

the longer use of the mould the  more serious the problem is.
