High Auto High Precision Slitting for 0.3-0.8mm PPGI and GI

These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.

1. Production Line Overview

• This slitting line is designed for thin gauge materials like galvanized, pre-painted, and aluminum-zinc coils. It provides precision slitting with minimal deformation, catering to metal sheet manufacturers, and those in need of high-frequency coil changes. The line’s advanced features ensure efficient and high-quality production, enhancing material handling and cutting performance.

2. Profile Description

• Hydraulic Decoiler → Tension Control → Slitting → Hydraulic Cut → Out Table → Scrap Coil Collection → Hydraulic Recoiler
• This slitting line begins with the 5T hydraulic uncoiler, which unrolls the material smoothly, followed by resistance rollers that gently control the tension. The rubber slitting machine ensures clean cuts, while hydraulic cutting delivers precise, no-deformation edges. Waste edges are collected, and the material is wound consistently by the hydraulic recoiler.

3. Key Focus

• High Compatibility: Precisely matches 0.3–0.8mm thin sheets, especially suitable for delicate materials such as galvanized, pre-painted, and aluminum-zinc coatings.
• Strong Protection: Rubber slitting and pressure arm design effectively prevent scratching and edge curling, safeguarding the surface.
• High-Precision Control: Automatic knife adjustment and tension control ensure accurate dimensions and tight coil formation.
• Convenient Material Change: Digital adjustments combined with the feeding cart save labor and improve coil change efficiency.
• Stable ROI: With a focus on quality, the design avoids redundancy and controls costs, making it suitable for long-term use.
