Optimum clamping forces and evenly distributed load on the tie bars are important parameters for die cast machines. Only perfect machine alignments ensures the quality of the parts and also extends the lifetime of tool and machine.
Parallelism in particular has an important role. If the platens are not quite parallel or the tool is not parallel, different tensile stresses occur in the individual tie bars. In the extreme case, these result in an overload on an individual tie bar, and thus in cracks or even breaks. It is therefore strongly recommended that at every change of the mould, the machine should be checked for parallelism.
This is done most simply and reliable by measuring the strain on the tie bar.
