Quality without compromise
Process control
Input control All inputs are checked according to internal specifications (sand, chemicals, paints, resins, etc.) using the appropriate laboratory equipment.
Forming mixture quality control The mechanical characteristics of the forming mixture are checked daily for each mixer with adequate equipment.
Cast iron processing control
Thermal analysis of liquid cast iron With the help of software, the nodulation process is controlled and information is received upon the quality of the metal in the pouring ladle, before casting.
Cast iron chemical composition is also checked before casting the part using:
- ARL spectrometer
- Columbus spectrometer
- ELTRA %C & %S analyzer
The temperature control of the liquid cast iron is done with the HERAEUS immersion device.
Cast iron mechanical characteristics control
For each batch, samples are cast to check the tensile strength, cast iron elongation and the KCU resilience.
Components of the infrastructure used:
- GALDABINI 20 kN traction machine with extensometer
- Fritz Heckert 40 kN traction machine
- Charpy impact machine
Control of the casting process, casting forms, and casting assembly
The tack of the refractory paint is checked daily, using the Ford cup, as well as the thickness of the paint layer deposited on the forms and cores.
The temperature control for the surface of the part is done before the knock-out, with the help of a contact thermometer inserted in the mold until it touches the hot part.
Castings control
An internal final check is performed according to standard procedures and specific procedures as a result of the client's requirements.
Direct visual control
Dye Penetrant Control
Ultrasonic control The NAMICON device is used with probes of different frequencies and various geometries of the contact surface.
Hardness control is done with:
- Laboratory hardness tester Brinell 3000 Kg for hardness control on samples attached to the casting
- Portable hardness tester ERNST for hardness control on the part
- Dynamic Portable Durometer - Type G Probe
Micrographic control The analysis of the metallographic structure is carried out with the help of the Olimpus optical microscope. Beforehand, the samples are polished on special grinding machines.
Dimensional control It is performed by protracting on the laying-out table using classic tools such as drawing calipers of various sizes.
Painting control In the painting process, the characteristics of the paints are determined by:
- Ford cup - for tack control
- Digital tester to control paint layer thickness
- Digital thermometers
Database
All process control and castings control parameters are introduced into a very detailed database.
Each piece is marked with the foundry logo, casting series and the manufacturing year. In this way we have a rigorous traceability of each item.
