Product Overview
This compact metal hemming machine is specially designed for folding and hemming thin‑gauge metal sheets. It bends the edge of metal panels to form neat, smooth folded rims, eliminating sharp cutting edges. Widely matched with roof panel roll forming machines, it is ideal for processing color steel, galvanized sheet and aluminum sheets used in roofing, wall cladding and ventilation duct manufacturing.
With a table‑type integrated structure, this hemming unit occupies little workshop space. Driven by chain‑gear transmission, it delivers stable and consistent hemming results. Simple setup and low maintenance make it perfect for small‑to‑medium metal fabrication factories and roofing component producers.
Core Features
✅ Compact Table‑type Structure
Benchtop all‑in‑one design, easy to place and connect with roll former production lines. Saves valuable factory floor space.
✅ Precision Multi‑roller Forming
Multiple sets of forming rollers gradually roll and fold sheet edges. Produces uniform, wrinkle‑free hemming profiles without damaging the painted surface of color coated metal.
✅ Reliable Chain‑gear Driving System
Chain and gear power transmission ensures steady feeding, reduces slipping during continuous operation. Stable performance for long‑time daily production.
✅ Adjustable Forming Specifications
Adjustable rollers support different hemming widths according to customer requirements. Quick parameter changeover for various sheet workpieces.
✅ Surface‑friendly Processing
Polished forming rollers prevent scratches on pre‑painted, galvanized and aluminum metal surfaces. Finished edges are smooth and burr‑free for safe handling.
✅ Easy Operation & Low Maintenance
Motor‑driven automatic feeding, minimal manual intervention. Simple mechanical construction for convenient inspection and part replacement.
