Annual savings, cost and payback for example plant mixer control

Good binder management measures are used in the vast majority of the foundries using bonded sand. 

Modem mould and core-making machines allow the production parameters of the various product types to be saved in an electronic database. This allows easy change-over to new products, without the loss of time and materials from finding the right parameters by simply using trial and error. For new products, the settings for similar products may be used to shorten the optimisation time. 

Reduction of the amount of waste sand and energy, through minimisation of the test mn period. 

Series production of small series with high production throughput. An errorless change-over requires good control and continuity of the sand quality. 

The investment cost for a core shooting machine depends on the core volume, and range from EUR 150000 (5 1) to EUR 400000 (1001). Operational costs are 5 - 10 % of investment costs
