Feramo. Gray cast iron foundry and patterns manufacturer of wood, epoxi and metal

Foundry technology

Melting and Casting

Liquid metal preparation is provided by hot-air cupola furnaces with melting zone diamater 1000 mm and with automatic charging system with output 7,5 t/hour.

Casting of liquid metal is provided through automatic casting machines with induction heating PRESSPOUR 5 CTO from ASEA and INVR 2500/100 from INDUCAL. Both automatic machines are equipped with metal stream graphite inoculation system of type MSI 90 from FOSECO.

Moulding

Moulding capacity is provided in particular by DISAMATIC automatic frameless moulding lines, namely: type 2013 Mk 4 A – mould dimensions 600 x 480 mm and type 2032 – mould dimensions 775 x 600 mm and frame moulding line Savelli F 1 with frame dimensions 800 x 800 x 250/250.

Core shop

Cores are manufactured by COLDOX AMIN methods on LAEMPE L 20, LAEMPE LKV-H 25, LAEMPE LL 20 and AVS-6 machiness.

Finishing operations

The fettling area is equipped with machines STEM B 12x16, PT 1800, PT 63 B, two TS 2000 machines and three TZV 1 machines. Finishing is carried out on AHS 600 grinding machines. During the completation works two kinds of primer coats can be optionally applied on the castings.

Technical preparation of production

To acquire a high quality of our castings we use a computer simulation of feeding the moulds in preproduction stage and metal solidification in the moulds. To manufacture patterns on CNC machines we carry on computer processing of received 3 dimension drawings.

Other processing techonologies

Machining

Our machinery enables to test mechanical machining of castings on conventional machine tools. Further we are able to bore different holes into the castings include screws till 16 mm for our customers.

Annealing

The parts of our machinery are also electric annealing furnaces for 2 to 5 tonnes of castings, in which is carried out annealing according to the customer requirements (e. g. to remove strain, to faciliate machining, and so on).
