Industries
We solve casting problems
Choose your industry. Challenge, solution and matching references.
Gearbox industry
Your challenge: Core-intensive gearbox housings with tight tolerances and high dimensional accuracy
Our solution: Series production of complex housings from 5–200 kg, proven in drive technology
Machine moulding
Parts we cast often
Gearboxes, pumps, motor housings — the same lines, the same materials.
Gearbox housings
In the 5–200 kg range we produce core-intensive gearbox housing raw castings in green-sand machine moulding, with reproducible dimensional accuracy on bearing, flange and sealing faces.
Pump housings
Core-intensive pump housing raw castings in green-sand machine moulding, dimensionally accurate on sealing and connection faces, with a uniform microstructure for robust series quality.
Electric-motor housings
In the 5–200 kg range we cast stator and motor housings in green-sand machine moulding, thermally and mechanically loadable, with consistent fits and run-out in series.

Certification
Trust for your purchasing team
Certifications de-risk your projects.
TÜV SÜD
DIN EN ISO 9001:2015
Quality certification to DIN EN ISO 9001:2015 for first-class castings
Benefit: Documented processes, traceable quality and structured complaint handling, important for your supplier approval.
QM/E² Cert
AD2000
Röth Guss is certified to AD2000 for cast iron conforming to the Pressure Equipment Directive.
Benefit: PED-compliant castings for valves and pressure-loaded components, the proof your purchasing team needs.
DMSZ
DIN EN ISO 50001:2018
Energy is an important topic for Röth Guss. We improve continuously and are certified to the latest standard.
Benefit: Predictable, sustainable production, a plus for your supply chain and CSR requirements.
Digital process transparency, your advantage as a customer
More certainty for your series
Even as a mid-sized foundry we invest in connectivity and data-based process control. The aim is repeatable quality, documented traceability and reliable deliveries, including small and medium series.
Traceability in minutes
We answer queries on batches or process parameters much faster, the process history of your casting is available centrally, not spread across systems for days.
More stable series quality
Sand preparation, moulds, melt and pouring are monitored as a network. Deviations are detected early, before they affect your series at scale.
Faster response to deviations
Causes can be analysed in a targeted way, affected batches isolated and corrective action taken. The basis is process data.
More predictable delivery dates
Fewer unplanned stoppages and less scrap mean more reliable series delivery and fewer surprises in your production.

HWS moulding line
The HWS moulding line has a box size of 1030×810×320/320 mm, optionally 370 mm height. It uses the SEIATSU air-flow squeeze process. The line produces uniform castings to tight tolerances. Piece weights: 5–200 kg. We focus on core-intensive, complex housings. A fully automatic pouring unit completes the line. Mould filling stays process-reliable.
Moulding shop
Disamatic moulding line
On our Disamatic with a mould size of 600x480x150–395 mm we produce small-format series parts of 0.2–30 kg economically in flaskless moulding. The line also suits smaller lots, from about 20 moulds per batch. A fully automatic core setter lets us produce complex, dimensionally accurate castings. The electrically heated automatic pouring furnace ensures even pouring and consistent castings.
