Flexible Duct Forming Machine SBLR‑600

Specifications, applications and operation

Specification breakdown. The Flexible Duct Forming Machine SBLR‑600 (double working stations) forms flexible duct from Φ80–Φ600 mm in non-woven fabric, PVC film and aluminium foil 0.02–0.08 mm thick, in continuous lengths up to 36 m. Material strip width is matched to duct size (about 35 mm at Φ80, 30–35 mm at Φ100–125 and 35–40 mm at Φ300–600). It forms at 65 m/min with fully automatic cutting, draws 7 kW on 380V / 50Hz / 3PH, weighs 680 kg, and has a mainframe footprint of 2000×1500×1800 mm.

Typical applications. Flexible duct manufacturing equipment supports a market that's grown rapidly with the rise of residential and light commercial ducted air-conditioning — semi-rigid aluminium duct, insulated flexible duct and canvas flexible connectors are now standard items in every HVAC supply catalogue. Typical buyers include flex duct OEMs supplying wholesale distribution, vertically integrated HVAC system manufacturers and large-volume installers running their own flex production.

How it works. Flexible duct manufacturing equipment combines coil feeding, helix forming, sleeve assembly and insulation wrapping into a continuous production line. The output is a finished length of insulated or uninsulated flexible duct, cut to the customer's required length, ready for packaging and distribution.

Quality, certification and after-sales. Like every machine in the Taokron catalogue, this unit is built to ISO 9001:2015 quality management standards and CE marked for European conformity. The office in Box Hill North, VIC has been operating since 1995 and Taokron holds 60+ invention and utility patents in HVAC ductwork machinery design. Each machine ships with a 12-month warranty on mechanical and electrical components, lifetime spare-parts availability, and 3–7 days of on-site installation supervision and operator training by an Taokron engineer. Remote support is available via WhatsApp and email, with engineer response within 12 hours and technical troubleshooting within 72 hours.

Where this fits in your workshop

Flexible duct machines run as a small dedicated cell, usually separate from the rigid-duct workshop because the products and the materials are fundamentally different. A typical flex cell has an aluminium-foil decoiler, the helical winder or sleeve forming station, an insulation wrapping station for insulated flex, an end-shrinking machine to prepare connection ends, and a packaging table. Taokron can supply the cell as a turnkey package or as individual modules to drop into an existing flex line.

Pre-purchase checklist

Use this list when you write the enquiry or when you compare two suppliers. Each line is something an Taokron engineer will want clarified before quoting.

• Diameter range matched to your distribution channel (residential vs commercial)
• Insulation type compatibility (glasswool, polyester, none)
• Maximum continuous run length per cycle
• Operator skill level — flex machines are typically run by 1–2 people
• Power demand at the heater elements, not just the main drive
• Compressed air spec if the machine uses pneumatic clamping

Operator and maintenance notes. The Flexible Duct Forming Machine SBLR‑600 is designed to be run by a single trained operator under normal conditions. Daily checks include lubrication of the forming rolls, inspection of the drive belts and chain tension, and a clean-down of the tool surfaces. Weekly checks add electrical cabinet inspection and a torque check on the main frame fasteners. Taokron ships every machine with an English operator manual, a maintenance schedule and a recommended two-year spare parts kit. Operator training is included in the 7-day commissioning visit, and a refresher session can be booked at any time within the warranty period.
