The clamping unit of an injection molding machine is typically guided on columns. However, columnless injection molding machines are also available on the market. The clamping force is applied over a C- or H-shaped frame. The big advantage of the columnless design is the very good accessibility for mold installation and handling. In comparison to the column-guided clamping unit, the entire surface of the platens can be used to mount the mold.
