The SMS group company Hertwich Engineering designs, supplies, constructs, and commissions machinery and equipment for the aluminum industry worldwide. It focuses particularly on aluminum casthouses, supplying:
1. Horizontal casting plants for ingots, busbars, and billets
2. Vertical casting plants for extrusion and forging billets
3. Open mold ingot casters (air & water cooled)
Horizontal casting plants
Very different products can be manufactured on horizontal casting machines, which is why they are also referred to as "universal casters". They are ideal for the production of:
- Foundry alloy ingots
- T-bars
- Busbars and anode rods
- Extrusion billets
Vertical casting plants
Hertwich also offers vertical casting plants (VDC – Vertical Direct Chill). These are based on a proprietary design. Several plants for casting billets for extrusion and forging as well as rolling slabs have already been put into operation. Hertwich VDC casting systems are equipped with internally guided ceramic-coated casting cylinders and are compatible with all major casting tool brands.
Some outstanding features:
- design as single and double VDC caster possible
- version-controlled management of casting recipes for continuous quality optimization
- active guidance of the operators
- fully automatic casting start-up to eliminate subjective operator influences; this leads to constant product quality and improved safety
- log tracking system of downstream inspection equipment enables identification of defective molds
- operator-friendly diagnostic system for improved maintenance efficiency
Compact-type remelt plants for long profile scrap and VDC casting
A VDC caster, together with a tiltable casting furnace, can also be used as a compact-type remelt plant for long profile scrap. Many extrusion operators choose this type of furnace to remelt clean profile scrap up to 7 meters long at rates of about 3 tons per hour.

Open-mold ingot casting
You don’t just get water-cooled ingot casters from Hertwich. We also offer you an air-cooled version. It comes with several improvements and provides an attractive alternative. Common to both types are excellent efficiency, reliability, and product quality.
The casting launder used by Hertwich instead of a casting wheel reduces the cascading effect. That significantly cuts dross formation. It also ensures more uniform ingot height. You choose the downstream packing stations you want, including stacking, strapping, weighing, or marking equipment. All these are available in automated or manual versions. Simply enter your recipe, and the automated casting start ensures perfect safety and operator friendliness.
