. Core Technical Features

High‑Precision Forming System

• Employs a multi‑pass progressive forming process, ensuring cross‑section dimensional accuracy of ±0.2 mm.

  
  

• Forming rollers are made of high‑strength tool steel, heat‑treated and precision‑ground to ensure long‑term stability.

  
  

• Equipped with an automatic roll‑gap compensation system for precise forming of materials with different thicknesses.

  
  

Multi‑Function Integrated Design

• Integrated online punching unit enables simultaneous, accurate processing of lock holes, hinge holes, and mounting holes.

  
  

• Optional auxiliary processing modules such as corner cutting, slotting, and embossing.

  
  

• Supports forming of multiple connection types (welded edges, snap‑fit, plug‑in, etc.).

  
  

Intelligent Control System

• PLC + touch‑screen control, capable of storing process parameters for various door‑frame profiles.

  
  

• Includes automatic fixed‑length cutting, production counting, and fault‑diagnosis functions.

  
  

• Optional vision‑inspection system for real‑time monitoring of forming quality.

  
  

Flexible Production Capability

• Quick mold‑change design with changeover time ≤20 minutes.

  
  

• Adaptable to different materials (galvanized sheet, stainless steel, aluminum sheet, etc.).

  
  

• Material thickness range: 0.6–2.5 mm (customizable up to 3.5 mm).
