Perforated roller shutter machine/shutter door slats roll forming machine

Product Introduction

The Automatic Perforated Roller Shutter Slat Roll Forming Machine is engineered for continuous manufacturing of micro-perforated and vision-slat roller shutter doors. Combining an in-line high-speed mechanical punching press with a precision multi-pass roll former, this production line processes galvanized steel (GI), pre-painted steel (PPGI), stainless steel, and aluminum strips into perfectly interlocking shutter slats featuring uniform ventilation perforations, smooth edges, and high structural integrity.

Designed for high-speed operation and minimal maintenance, the system includes integrated strip guiding, custom profile-matched hydraulic shearing, and an intuitive PLC touchscreen control unit.

Key Highlights & Advantages

• Synchronized In-Line Punching: Integrated mechanical punching press and automatic feeder execute high-density micro-perforations or slot patterns across flat coil strips prior to roll forming.

• Precision Interlocking Profile: CNC-machined 45# steel rollers with 0.05mm hard-chrome plating form tight, smooth-sliding interlocking hooks without scratching pre-painted coatings.

• Contour-Matched Hydraulic Post-Cutting: Four-pillar hydraulic cutter featuring Cr12MoV quenched alloy steel dies cuts along the exact slat cross-section without end deformation or burrs.

• Smart PLC Automation: Delta touchscreen panel paired with optical rotary encoders enables precise slat length tracking, automated batch counting, 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.Pre-punch:Customized according to product punching requirements

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

4.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

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

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

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

8.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.
