Technology
Melting/ Melting shop
Two EGES 3 MW medium frequency induction MELT & HOLD melting furnaces (volume 2 x 4 tons, melting output of 6.1 tons per hour). Material charging is secured using a vibration cart common for both furnaces.
Moulding Frameless moulding line DISAMATIC 2013 LP/PLC-B, vertical parting line, with sizes of sand moulds ranging from 535 x 650 x 120–360 mm.
Technical capacity of up to 300 moulds per hour based on the type of casting and presence of cores; sand mixture is prepared in 2 mixers with a capacity of 1–1.2 tons using reversible sand cooling.
DISA DTC-2 blasting machine with polygonal drum.
Production of cores
4 “Schalco“ (hot box) machines; we purchase the core mixture.

IRON FOUNDRY DIVISION
Quality control of material according to the process flow.
An optical emission spectrometer Q4 TASSMAN from Bruker-Elemental is used directly at the smelting furnace where chemical analysis of each smelting process is carried out. Samples are subsequently taken from each smelting procedure according to internal procedures or according to customer requirements, where sampling castings are tested in the laboratory for metallurgical and mechanical properties.
Capabilities and laboratory equipment
Metallographic examination / macrostructure and microstructure of the material: grinding preparation for the semi-automatic Buehler grinder/polisher. Inverted metallographic microscope
NIKON ECLIPSE MA100 (50x – 500x), NEOPHOT 32, Carl Zeiss (50x – 1000x).
Possibility of evaluating the structure using image analysis with NIS-Eements.
