Laboratory for analysis and final inspection

Technical office and laboratories

Fonderie Palmieri makes available competence and professionalism, collaborating during the phase of design and development, finding solutions that can facilitate the production process. Our technical staff constantly analyses the various steps of the production processes, guaranteeing a continuous analysis of the whole production. A cutting-edge laboratory allows to carry out all the destructive and non-destructive tests) required.

Chemical analysis

For chemical analysis we use two optical emission spectrometers. One spectrometer is placed in the melting shop and one in the laboratry. 100% of our iron production is constantly checked for 28 elements.



Metallographic Analysis are carried out using an Olympus light microscope with magnifications up to 500x according to ISO EN 945-1 and ASTM 247.

Analisi termica

Thermal analysis

A sample from every ladle is withdrawn and poured in glass of sand connected to a thermocouple. The changes in temperature of the sample are monitored by means of a specific software.

Pendolo charpy

Analysis of mechanical characteristics

Mechanical characteristics of the production are constantly controlled by tensile testing (according to ISO EN 6892-1), impact testing (according to ISO EN 148-1) and hardness tests (according to ISO EN 6506-1).


Thanks to the introduction of modern facilities and monitoring techniques, the department has evolved consistently and a group of highly qualified operators monitors the phases of the process. System procedures and operational instructions are constantly updated to satisfy changes in laws and customers’ requests. Relevant specifications are handed to the suppliers to keep high quality standards even with regard to incoming goods. Within the inspection department the following tests are carried out:

Ultrasonic testing

The most efficient and immediate testing method in order to detect internal defects on cast irons. Ductile iron is controlled in compliance with ISO EN 12680-1, -2, -3 and UNI EN 583-1, -2, -5.

BNIF Campioni

Surface roughness control

Our employees check the correct condition of the cast part surfaces using BNIF comparative samples in accordance with the DIN EN 1370 standard.


Dye penetrant inspection

Dye penetrant inspection is used to ensure integrity of a surface (to highlight little cracks or porosity that are not visible to the naked eye).


Machinability testing

Controls the absence of hard spots of iron carbides.


Magnetic particle inspection

Magnetic particle inspection is a method for detecting cracks in or near the surface. The test is performed according to the standard DIN EN 9934:2017. Our employees are qualified according to DIN EN 9712 to carry out the tests and to certify them.


Endoscopic control

Technique that allows to search for superficial anomalies within details. Such test can be carried out whenever there is an inward access to be checked.

Controllo durezza


Fonderie Palmieri has the facilities to perform various hardness tests, the most common being Brinell.

These are carried out in accordance with the DIN EN 6506-1 standard.

The Rockwell hardness test is conducted in accordance with the DIN EN 6508-1 standard and applied mainly with our wear-resistant cast iron grades.

All hardness testers are continuously verified by calibrated comparative samples.

Controllo dimensionale

Dimensional control

Several 3D measuring arms with laser scanning are used to check the dimensions of our cast parts. With these instruments, we compare the mathematical model of the three-dimensional drawing approved by the customer with the cast part produced. The versatile control instruments are also used for continuous inspection of the dimensionally relevant components of the moulding line, such as clamping devices and moulding boxes.


Radiographic controls

X-ray analysis is used to detect defects in the casting at any depth. These inspections are carried out by our suppliers according to European and American standards.


Visual inspection

Visual inspection is used to detect visible macroscopic errors. Our employees are qualified according to EN 9712 and abilitated to certify the visual inspection.


Ultrasonic velocity testing

The grade of spheroidization in the ductile iron matrix can be determined using ultrasound.
