It is currently connected and can be demonstrated under actual production conditions, allowing the buyer to inspect the complete process and the quality of finished ducts before purchase. Key Features * working diameter range: Ø80–1600 mm * production speed: up to 60 m/min * installed power: 11.25 kW * galvanized steel: 0.4–1.2 mm * stainless steel: 0.4–0.7 mm * aluminium: 0.4–1.3 mm * pneumatic sheet metal strip decoiler * touchscreen control panel * automatic lubrication system * automatic forming angle adjustment Lrodpfx Aszt Ni Eef Sot * automatic rotary cutting * automatic fault detection * smooth ducts or single/double reinforcing beads * external spiral lock seam * machine weight: approx. 2,900 kg 39 Forming Heads Included The machine comes with an extensive set of 39 forming heads covering 22 diameters: Ø80 (1), Ø100 (2), Ø125 (3), Ø160 (3), Ø200 (3), Ø250 (3), Ø315 (3), Ø355 (2), Ø400 (2), Ø450 (2), Ø500 (2), Ø560 (2), Ø630 (2), Ø710 (1), Ø800 (1), Ø900 (1), Ø1000 (1), Ø1120 (1), Ø1250 (1), Ø1400 (1), Ø1500 (1), Ø1600 (1). The set therefore covers the full working range from Ø80 to Ø1600 mm, with additional heads for the most commonly produced diameters. Spare Parts Package A comprehensive package of spare and wear parts is included, such as forming and guiding components, lock-seaming rollers, pneumatic components, cutting knives/rotary cutting components and decoiler braking parts. This provides an important operational reserve and helps minimise downtime without having to immediately source essential parts internationally. Production-Ready + Training The buyer receives a fully configured and proven production machine, not an uncommissioned unit requiring extensive setup and adjustment. We provide on-site commissioning assistance and operator training at the buyer’s facility, including machine operation, forming head replacement, adjustment for different diameters and sheet thicknesses, maintenance and trial production. The machine can be inspected and demonstrated during actual spiral duct production before purchase.
