Over 30 Years' Experience in Stack Molds.

männer stack molds require roughly the same closing force as single-cavity molds. This means that by using stack molds with two or four parting lines, you can obtain two to four times the output with virtually the same closing force compared to using single-cavity molds.

For its stack molds, männer relies on more than 30 years of experience and, with it, sophisticated high-precision moldmaking technology, in addition to hot runner technology specially developed for use with stack molds.

The valve gate hot runner system (männer MES) has the benefit of injection points positioned along a single axis and – thanks to the special submanifold – does not compromise the assembly height of the middle platen. The split snorkel, meanwhile, provides sufficient room for handling systems.
