Spiral Duct Forming Machine — New | BLKMA, Ma'anshan, China

The BLKMA Spiral Duct Forming Machine automatically produces round spiral tubes in different diameters and lengths according to customer requirements, using duct molds to form the spiral duct. The machine is designed for ease of operation and accurate diameter formation, with a high-speed synchronous automatic cutting system enabling customizable duct lengths cut precisely to size.

Two models are available — the BAL-1500 and BAL-1500C — differing in diameter range, thickness capability, feeding speed, and power draw, giving buyers flexibility to select the configuration matching their production requirements. BLKMA has optimized the machine's structure multiple times to enhance speed and molding quality, earning recognition from customers worldwide for producing aesthetically pleasing, precisely sized ducts.

To complete spiral duct processing, this machine is typically used alongside complementary equipment such as round elbow machines and angle steel round rolling machines.

Why Choose This Spiral Duct Forming Machine?

A spiral duct forming machine remains the single most critical piece of equipment in round spiral duct production — the quality of its forming mechanism directly determines the dimensional accuracy and finish of every duct produced. BLKMA's machine stands out through its use of internationally recognized components rather than unbranded generic parts: a German Siemens control system, German Schneider Electric system, German FESTO cylinders, a Beijing Huade hydraulic system, and a Japanese OMRON encoder — combining reliability from established global brands across every critical subsystem.

This component sourcing strategy matters practically for international buyers: replacement parts and technical support for these globally recognized brands are typically far easier to source locally than parts for unbranded components, reducing long-term downtime risk.

Frequently Asked Questions

What's the difference between the BAL-1500 and BAL-1500C models?
The BAL-1500C covers a slightly wider diameter range (80–1500mm vs. 100–1500mm) and offers a faster maximum feeding speed (45 m/min vs. 35 m/min) at lower power draw (9.5kW vs. 16kW), while the BAL-1500 has a larger overall footprint.

Why does BLKMA use international brand components?
Using recognized global brands (Siemens, Schneider Electric, FESTO, OMRON) for critical subsystems makes replacement parts and technical support easier to source locally for international buyers, reducing long-term downtime risk compared to unbranded components.

What additional equipment do I need for full spiral duct processing?
To complete duct processing, this machine is typically used alongside complementary equipment such as round elbow machines and angle steel round rolling machines.

Can this machine produce custom duct lengths?
Yes. The machine features a high-speed synchronous automatic cutting system that allows precise, customizable duct lengths based on production requirements.

What material thickness can this machine process?
The BAL-1500 handles 0.5–1.2mm material, while the BAL-1500C handles a slightly wider range of 0.4–1.2mm.

Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.

Should I buy new or used?
This model is available new, from a manufacturer with duct machinery experience since 1994.
