Moulding shop and melting shop
The SHB plant in Leipzig is one of the most advanced foundries in Europe. Whether you request cast parts in series production or individual parts, SHB is equipped to meet the most stringent demands. We are able to achieve maximum flexibility and efficiency with three moulding methods.
| machine moulding | size | 1400 x 1300 x 400/400 mm |
| weight | 20 kg to 700 kg | |
| volume | mid-range to large series | |
| mechanised hand moulding | size | up to 3000 x 1800 x 900 mm |
| weight | u p to 8.000 kg | |
| volume | small and mid-range series | |
| Hand moulding | size | max. height 1800 mm |
| weight | up to 8.000 kg | |
| volume | one-off pieces and small series |
Special manufacturing facilities provide us with two high performance electric arc furnaces, each having a 7.5-tonne capacity for the melting of low and high alloy steels. With the help of a 1.1-tonne modern induction furnace, we produce materials and batch sizes flexibly.
Mechanical processing
Mechanical processing is carried out in our company using conventional as well as modern NC and CNC-controlled machine tools. Turning, milling, planning or sinkhole drilling – we offer the perfect solution for every need.
B = borehole, depth = 1000 mm
The size of the workpiece depends on the tool and machining type.

Fettling shop and Heat Treatment
In our modern fettling shop, the components obtain the required finishing through flame cutting, jointing, welding and reciprocating grinding. The essential mechanical and technical values can be adjusted using a correct heat treatment method.
Heat treament methods
- Annealing
- Quenching and Tempering in various mediums (tempering after quenching):
- Air (different movements)
- Hardening oil (modified high- Performance quenching oil)
- Polymer solution (different concentrations possible)
- Water
- Austenitising
- Soft annealing
- Stress relieving
