High Precision Flexible Duct Connector Machine For 0.3-0.6 Mm Material

Designed for high-efficiency production of flexible connectors, this full-automatic roll forming line is engineered and manufactured by Dongguang Hengfu Roll Forming Machine Co., Ltd. It is specially built to process galvanized steel sheets and fire-resistant fabric, delivering stable, high-quality finished products for ventilation, pipeline, and dust removal systems. With reliable structure, precise forming, and easy operation, this machine provides a cost-effective and durable production solution for manufacturers worldwide.

This integrated production line combines a complete workflow: uncoiling, servo feeding and punching, roll forming, secondary punching, cutting, and material collecting. It supports galvanized steel with a thickness of 0.3-0.6 mm and width of 50-105 mm, as well as fire-resistant fabric from 120 mm to 450 mm. The final flexible connector width ranges from 180 mm to 600 mm, fully meeting diverse project requirements. The automatic process ensures high productivity, consistent dimensions, and stable output at a speed of 6-8 meters per minute.

Built with heavy-duty industrial components, the machine features 12 forming stands for smooth and accurate profile shaping. The main shaft is made of Cr40 steel with fine machining, while the forming rolls adopt high-grade Gcr15 bearing steel with 0.05 mm hard chrome plating for excellent wear resistance and long service life. The frame is constructed with 80*80 square tubes and 14 mm thick vertical plates, ensuring strong stability during continuous operation. Powered by a 3 KW main motor and controlled by a PLC system, the machine runs steadily under 380V/50Hz/3Phase power supply.
