FIN MILL

Efficient, precise, future-proof: corrugated fin rolling machines for modern lamella production.

Efficiency and precision for lamella production

Rely on scalable precision systems that efficiently and reliably process even complex lamella geometries and high lamella densities. Technologically advanced – for future-proof heat exchanger production at the highest level.

User-friendly & automated

Automate your processes. Rely on maximum user-friendliness.

Everything digital. No manual handling:
Control all processes centrally via the HMI – intuitively, safely and efficiently
Tool detected. Process secured:
NFC detects components immediately—ensuring fast access, safe processes and error-free work.
Intelligent lubrication:
Oil consumption automatically adapts to speed and bandwidth—ensuring clean processes with optimal use of resources.

ZELTWANGER thermal management corrugated fin rolling machine

Efficient & powerful

Maximize your output – with a high number of cycles, short set-up times, and stable performance

High-speed cutting:
Up to 180 cuts/min (single track) or 360/min (double) – with constant cutting quality and a maximum belt speed of 6.5 m/s.
Tool-free conversion—ready in minutes:
Quick-release system, tool-free changeover and maintenance-free components reduce set-up time by up to 80%—for maximum flexibility and availability.

Precision & Quality

Ensure the highest quality. Measure, control and monitor automatically – in real time.

Cutting without length fluctuations:
The flying guillotine guarantees consistently precise cutting lengths.
Quality 100% inline tested:
Inline height, density and Louver Angle Measurement System – maximum control for every part.
Precise to the last detail:
± 0.05 mm belt guide at 6.5 m/s – fully automatically controlled.
Constant slat height:
Belt force control keeps heights constant – even under changing conditions.
Automated belt guidance:
± 5° belt path correction for perfect cutting quality.
