The table gives a overview of thevariety of vertical casting cylinders used. With the exception of the cardanic suspended plunger- casting cylinder, which is still in use in casting plants with external table guidance, all casting cylinders have an integrated, highly precise table guidance and a bending resistant piston rod. The advantage of this solution is due to a minimum possible friction as well as the protection of the entire casting cylinder guidance. This modern casting cylinder construction can be supplied with or without integrated anti- rotation protection.
By application, in which the plunger and table weight is not enough to ensure a minimum starting pressure, differential type casting cylinders of can be used. Through the annulus pressure, a uniformly controlled retraction can be ensured from the load free starting position to the maximum table weight. Of course, the casting cylinders of the differential cylinder construction type also have an integrated rod guidance with bending resistant construction of the piston rod as well as an integrated anti- rotation protection over the entire stroke.
