WHAT IS CTA
The CTA is a CNC rotary forming machine designed for hot neck and bottom forming of industrial tubes.
It performs controlled rotary forming operations at elevated temperatures, using gas blowtorches or induction systems to ensure stable material deformation. Programming is managed through DENN CAD-CAM, enabling precise, repeatable production cycles.
DENN machines can be integrated into automated production lines.
Why choose CTA?
BENEFITS
Reliable hot forming control
Integrated heating and temperature monitoring ensure stable deformation conditions throughout the cycle.
Repeatable neck and bottom geometry
Multi-pass forming using rollers or fixed tools ensures consistent results part after part.
Engineered for pressure-tight applications
Bottom closing supported by inert gas injection to minimise oxidation and micro-cracks.
Production-ready integration
CNC-controlled cycles and programmable sequences allow seamless inclusion in industrial workflows.
PARTS & MATERIALS
Industrial tube closing and neck forming applications
From cylindrical tubes, the CTA produces necked and closed-bottom parts designed for pressure containment and structural integrity.
Typical applications
Technical gas bottles, LPG cylinders, and other industrial pressure containers.
Materials
Steel and aluminium.
