The processing equipment of the foundry is represented by the two moulding shops – machinery and manual. The machinery moulding shop is equipped with an automatic shaping line with the impulsion system of bentonite-bonded sand compaction.
The manual moulding shop is equipped with continuous mixing tanks of furan self-solidifing sand mixture. 100% of reclaim from the mechanical reclamation is used for the sand mixture preparation.
AUTOMATIC MOULDING
The horizontal FA casting line with pulse moulding into a bentonite mixture represents the basic manufacturing equipment for medium and large-scale casting production.
The maximum annual capacity of the line in a three-shift system is approx. 5.000 t of castings. The equipment is in permanent two-shift operation and is subject to regular maintenance and annual overhauls.
