The density of hand-made is not enough, it's light, while the density of machine pressure is high, it's heavy, each has their own benefits
Withstanding voltage strength is not the same, the strength of the mechine-made is higher
Hand-made brick mainly produces brick that is not easy to produce molding Machine pressure brick adopts 100 tons of press machine to mold the density of hand-made brick is not enough, it's light; machine pressure bricks can only produce bricks that produce molding at a time, hand-made bricks mainly adopts hydraulic vibration molding machine
