Description
High Speed Flexible Connection Production Line Automatic HVAC Duct Connector Making Machine
Dongguang Hengfu Roll Forming Machine Co., Ltd. delivers a fully automatic flexible connector production line designed for high-efficiency, stable, and precise manufacturing of HVAC soft connectors. This integrated line combines uncoiling, servo feeding, punching, roll forming, cutting, and collecting into one smooth workflow, delivering consistent product quality, strong durability, and easy operation.
With reliable performance and mature design, it has become a trusted solution for HVAC manufacturers and metal processing factories around the world.
Processing Capabilities
This production line supports a wide processing range to meet diverse production requirements:
  • Galvanized steel sheets: 0.3-0.6mm thickness, 50-105mm width
  • Fire-resistant cloth: 120mm to 450mm width
  • Finished flexible connectors: 180mm to 600mm width
This adaptability makes the line ideal for various duct connections, ventilation systems, and industrial pipeline applications.
Robust Construction
The forming host is built with industrial-grade components for long-term stable operation:
  • 12 forming stations with high-precision Gcr15 bearing rollers
  • CNC machining with 0.05mm hard chrome plating for smooth forming
  • Main shaft made of Cr40 steel with precision finishing
  • Heavy-duty 80×80 square tube frame with 14mm thick vertical plates
Performance & Control
Driven by a 3KW main motor with cycloidal pinwheel reducer, the line achieves a stable output speed of 6-8m/min. The professional PLC control system enables accurate action coordination, reliable punching, and precise fixed-length cutting.
Sprocket and gear transmission ensures stable power delivery with low noise and low failure rates, supporting long-hour continuous production and reducing labor costs.
Complete Configuration
The complete production line includes:
  • Forming host
  • Four sets of punching and cutting dies
  • Servo feeding and punching unit
  • Hydraulic power station
  • Two electric uncoilers
  • One electric coiler
Every component is carefully selected and strictly assembled to ensure excellent performance and easy maintenance.

Frequently Asked Questions
How should the machine be stored when not in use for an extended period?
Disconnect the power, clean the machine, apply anti-rust oil, cover it with a dust cover, and store it in a dry environment.
Can a single machine produce multiple types of profiles?
Standard models are typically designed to produce one specific profile type per machine. However, customizable models—such as those with interchangeable rollers, double-layer machines, or triple-layer machines—can be configured to enable a single machine to serve multiple purposes.
Does the machine require a foundation?
It simply requires a level concrete floor; no complex foundation is necessary.
Does the machine require disassembly for transport?
The core structure remains intact; only the auxiliary components are removed to ensure that precision is maintained.
There are no professional maintenance personnel available locally; what should we do in the long run?
We provide lifetime remote video guidance; most issues do not require on-site repair.
