Hunter Production Line
An automatic frameless forming line, based up a Hunter forming machine, with a jacket size of 600 × 800 300/300mm, pouring line, cooling tunnel, vibrating pan, sand cooling DISA with a fluid bed. The production line is computer controlled. We produce castings weighing from 3 kg to 70 kg.
Sand Thrower with Finishing Frame
- Forming of bentonite mixes
- Frame size: 1000 × 1200mm
- Casting Weight: 300 kg
- Intermediate Series
Furan
The furan castings are produced from both steel, ductile and flake graphite cast iron, weighing from 25 to 1800 kg.
The forms are produced from a self-hardening mix, with furan resin. The form mix is made by a mixer, a product of WOHR 25t/h,1ss. It is poured into frames from 600 × 600mm to 2200 × 2200mm. The modeling for low run production is done by wooden models. For larger production batches, the modeling is done by wooden models placed onto wooden sheets. These sheets are placed on automatic tracks, a product of Axeman. Removal of the sand forms, sand cooling and moistening, are done by products of GUT.
Aggregate Melting
- The foundry is equipped with and electric arc furnace OTO 3 with a capacity of 4.5-5t of liquid metal.
- Additionally, the foundry is equipped with a crucible induction kiln with a capacity of 2t + 0.5t.
Production of Cores
Handmade cores with use of Cold-box core system.
Surface Repair
- Steel shot blasting machine (hanging chain blaster, drum blaster)
- Hand blasting (Blasting room)
- Grinding (Pendulum grinder, hand grinding, grinder pedestal)
- Priming of castings
- Application of corrosion inhibitor
Heat Processing
Heating processing of castings is carried out in gas kilns. These kilns are a tunnel conveyer furnace, a chamber kiln, and a carousel kiln.
- Annealing Furnace - normalized annealing
Continuous annealing furnace, conveyer annealing furnace for castings of 4 × 5m) - Heating processing of metal - hardening is carried out in cooperation with our partners.
