Flat Roller Shutter Slat Roll Former/Roll-Up Door Slat Roll Forming Machine

Product Introduction

The Automatic Flat Slat Roller Shutter Roll Forming Machine is an industrial-grade production line designed for continuous, automated manufacturing of modern flat-faced roller shutter slats. Engineered with a heavy-duty reinforced steel chassis, precision CNC-machined forming rollers, and a 4-pillar contour-matched hydraulic post-shearing system, this machine converts galvanized steel (GI), pre-painted steel (PPGI), stainless steel, and aluminum coil strips into perfectly flat, interlocking door panels.

Flat profile roll-up door slats provide superior architectural aesthetics, improved structural wind-load resistance, smooth sliding operation, and low maintenance—making this production line an essential asset for commercial, industrial, and high-end residential door manufacturers.

Highlights

• Ultra-Flat Surface & Precision Interlock Geometry: Designed with optimized multi-stage progressive roller passes that prevent center bowing, oil-canning, and edge warping, ensuring crisp flat panel faces and smooth-sliding interlocking joints.

• Chrome-Plated CNC Forged Steel Rollers: Manufactured from high-grade 45# forged steel (or optional GCr15 bearing steel), CNC precision machined, and hard-chrome plated ($0.05\text{ mm}$ thickness) to protect pre-painted and galvanized coil surfaces from scratches.

• Guided 4-Pillar Contour Hydraulic Shear: Equipped with Cr12MoV alloy die steel blades subjected to vacuum heat treatment ($\text{HRC 58–62}$). The cutter dies are precision-profiled to match the exact flat slat cross-section, guaranteeing clean, burr-free cuts without deforming the interlocking hook profile.

• Intelligent PLC Touchscreen Automation: Integrated Delta PLC control system paired with high-resolution rotary encoder tracking enables fully automated length control, batch counting, manual/automatic operational switching, and fault diagnostics.

Production Workflow

Detailed description

1.Decoiler:Used to stand the steel coil and uncoil, keep them working stably. Manual and automatic options available

2.Sheet guide device:Leveling machine ensures the flatness of the raw material

3.Roll forming system : Roller surfaces polish, hard plating dealing Polished surface and heat treatment towards molds can keep the molding plate surface smooth and not easy to be marked when it is being stamped

4.Main motor:The main motor provides power to the forming rollers through chains or gears

5.Hydraulic cutting : Automatic cutting as target products length Blade material: Cr12, quenching treatment Hydraulic cutting and electric cutting available

6.PLC control system : Button press and screen touch operate Target piece`s length is adjustable Work automatically The system operate easily

7.Pump station Hydraulic oil into the hydraulic oil tank, the pump drives the cutter work Hydraulic oil: 46# Oil add capacity: oil add 3/4 of box capacity Oil pressure: 8-10 MPa.
