In TORUN DIE CASTING operations, the vacuum has been used for a while to provide the end-users with the best quality castings. Over the past 20 years, the complexity of the parts and market specifications have significantly increased. Customers require casting parts without air entrapped and with different walls thicknesses. To meet these highly demanding specifications, we design our own dies by combining calculation and multiple simulations to achieve optimum results. In this pursuit of excellence, the expert staff of FONDAREX is supporting TORUN by performing application studies to ensure optimum integration and performance of the vacuum system in the high-pressure die casting machine.
