Each Lucco Borlera product is the result of a careful analysis of the functional specifications of the component, which in 95% of cases is intended for the Automotive sector. Over the years, this important Turin company has earned a leading position as a supplier of components for electronic control units and mechanical parts for the electric cars of the most successful European manufacturers. These are often products that are processed and assembled by Lucco Borlera and which must satisfy specific qualitative requirements, such as the absence of contamination by residual particles and which must undergo bonding and sealing treatments, or chemical and painting treatments, or tests. sealing. In order to guarantee the quality required of its products, Lucco Borlera requested our support to identify the critical points of the lubrication of the molds and to carry out a process optimization study. We then defined together an adequate number of products on which to carry out the tests and applied our optimization methodology, which involves the analysis of the thermal mapping of the mold surfaces using the iCast Lube Analyzer software. Based on these analyses, we chose a lubricant from the E-CASTING family and conducted the test campaign. The final result of the optimization, analyzed with our iCAST EVO application, was a reduction in the annual cost of mold lubrication by 50%, thanks to the reduction in cycle time and lubrication and blowing times, an increase in annual production of 21 %, and a 33% reduction in costs related to waste water disposal and water consumption. To these results we must add the zeroing of the charge costs for non-compliant batches, which can sometimes seriously aggravate the profitability of some productions. The combination of Lucco Borlera's production skills, our optimization methodology and the E-CASTING line lubricants, have made it possible once again to make the diecasting process more profitable for the foundry and more sustainable for the environment, guaranteeing to castings the quality required by the customer.
