Product description
Corrugated Panel Roll Forming Machine
The Garage Door Panel Roll Forming Machine from LotosForming is a continuous cold forming line for producing sectional garage door panels from pre-painted, galvanized, or aluminum coil. Raw coil is fed through a series of precisely engineered roller stations. Each station bends the strip gradually until the finished panel profile is reached, with consistent dimensions, a clean surface, and straight edges. The line is built for manufacturers who need stable output, repeatable quality, and minimal material waste.
Key Features :
- High production speed: The machine forms at up to 30 m/min (without punching), which suits high volume garage door panel production.
- Precision roller tooling: The rollers are made from high grade alloy steel, heat treated, and CNC machined. They hold tight profile tolerances and resist wear over long production runs.
- Surface protection: The forming process is designed to protect pre-painted and coated coil from scratches and coating damage, so panels need little or no finishing.
- Rigid, durable structure: A heavy-duty welded frame and robust drive system keep the line stable and vibration-free at high speed.
- Automatic cutting: A hydraulic cut-off system cuts panels to length accurately without stopping the line.
- PLC control system: The touchscreen interface lets operators set panel length, batch quantity, and speed. It also supports fast changeovers and simple operation.
- Optional configurations: Options include hydraulic decoilers, pre-punching or embossing units, foaming integration, and an automatic stacking system.
Work Flow :
Step 1#: 8 ton hydraulic double head decoiler + cart →Feed guide + manual strip pulling →Forming main machine→ 5-hole punching (left + right)→ Notching (left + right)→Hydraulic servo tracking cut-off → electric conveying platform (not marked on the drawing)
Step 2#: Roller shutter door sheet→Offline punching station (not designed)
