The automatic block making machine applies the high-strength structural steel and special welding technique for its mainframe. The firmness of the mainframe allows the whole machine to come with good rigidity and vibration resistance.The guide pillar of this machine applies the ultrastrong special steel. By virtue of the chromate plated treatment, it perfectly resists torsion and abrasion. Additionally, the four guide pillars together with the ultra-long guide bearing make the pressure head and mould move accurately. This moving system adopts the special device that is good for lubrication, thus avoiding abrasion.
