Equipment and production technology
Ferroalloy castings
The core assortment is represented by a machine production of castings on the moulding lines, where we produce castings of up to 500 kg, accuracy category GTB 16. It is a production of moulds of single bentonite mixture by pressing, jolting and jolting with final pressing by a split pressing head. Moulding frame dimensions of our moulding lines are as follows:
| Moulding frame dimensions (mm) | Casting weight (kg) |
| 1,450 x 900 x 400/400 | 5-500 |
| 700 x 500 x 200/200 | 5-25 |
| 1,000 x 750 x 350/300 | 15-120 |
| 1,000 x 750 x 300/200 | 15-120 |
| Cylinder line – casting jigs Ø190/290 |
Aluminium alloy castings
These castings are produced by sand mould or gravity die-casting.
| Technology | Casting weight (kg) | Accuracy class |
| Manual sand moulding | 0.2 - 100 | GTB 15/5 |
| Machine sand moulding | 0.4 - 40 | GTB 15/5 |
| Gravity die-casting | 0.1 - 25 | GTB 14 |
For higher weight categories of up to 150 kg, please contact our sales representatives.
