FINISHING AND TESTING
After shake-out, the castings enter a DISA CT4 shot-blasting belt machine where they are blasted with grit prior to riser removal. All phases are fully automated.
The castings are then subjected to final processes, which depend on the customers’ specific requests: deburring, coating, mechanical machining.
Full compliance with the international standards is guaranteed by:
– Chemical analyses (ARL 3460 spectrometer – 18 elements)
– Tensile and hardness tests (GALDABINI and HECKERT machines)
– Dimensional tests (gauges; depth gauges; scanning machine)
– Micrographs (LEINZ microscope; KRAUTKRAMER ultrasonic system; GOM 5M scan)
All the data acquired are processed and outlined in the 31B test certificate.
