Additional activities, which are executed at the foundry.

HEAT TREATMENT:

Heat treatment is done with a heat treating furnace “SDO-125” – Bulgaria. Tmax=1000 o C; The dimension of the working chamber is: 2200 x 1000 x 1000 mm. The following processes are performed there:

• stress relieving of the castings from gray cast irons;
• ferritizing annealing of the castings from nodular cast iron;

PRIMING:

At the customer’s request priming of castings can be accomplished.

CONTROL:

In order to ensure the high quality and the perfect execution, shall be controlled the following:

• Chemical control,
• control of mechanical properties,
• hardness,
• metallographic analysis,
• sand examination.

Central laboratory:

The chemical laboratory has a vacuum spectrometer – new generation Spectromax for analysis of 26 chemical elements (for ferrous metals) and equipped with computer. The metallographic laboratory has technology for metals structure testing including microscope NEOPHOT2. The mechanical tests of the metals are made with other machines for hardness, toughness and tensile strength. The tests of the sands and paints are carried out in a separate part of the laboratory with the devices GEORG FISHER.All of the devices have undergone obligatory tests, calibration and certification by the licensed institutions.

Dimensions control:

Dimension control is performed by qualified personnel with a large scale of devices and appliances for measurements upon a table for tracing of the castings.

Magnetic particle examination:

At customer’s request magnetic particle examination could be done.

CERTIFICATES:

IHB METAL CASTINGS issues a certificate for the quality for all of the manufactured products as follows:

• Certificate for chemical control;
• Certificate for mechanical properties, hardness and metallographic analysis;
• Certificate for dimensions control;
• Certificate for magnetic particle examination;
• Heat treatment’s diagram;
• Certificate for sand examination and others.

The staff of the IHB METAL CASTINGS AD has the necessary professional qualifications, knowledge and experience to produce castings with guaranteed high quality.

In the foundry has implemented a system of quality management and has a Operating Licence according to ISO 9001.
