Product Overview
The 686+762 Double Layer Roll Forming Machine is a highly efficient, space-saving metal panel manufacturing solution designed for international construction and steel structure markets. Engineered with a dual-deck architecture, this versatile equipment allows operators to produce two distinct corrugated roofing profiles (686mm and 762mm effective widths) from a single machine. By integrating advanced cold roll forming technology, it significantly reduces factory footprint and capital investment while maximizing production flexibility. This automatic color steel tile press is ideal for export and widely used in industrial warehouses, commercial buildings, and residential roofing projects.
Core Features & Technical Advantages
- Dual-Profile Versatility: Equipped with independent upper and lower forming stations, enabling quick switching between 686 and 762 trapezoidal roof sheet profiles without replacing the main frame.
- Intelligent PLC Control System: Powered by an industrial-grade PLC (e.g., Delta) with a user-friendly touchscreen interface. It supports multi-language operation, automatic length counting, and precise batch production with a cutting tolerance of ±2mm.
- Robust Cold Roll Forming Structure: The main chassis is constructed from heavy-duty welded steel, stress-relieved to prevent deformation. The forming rollers are made of high-grade 45# steel with hard chrome plating, ensuring durability and a flawless surface finish on the panels.
- High-Precision Hydraulic Cutting: Features an integrated hydraulic shearing system that automatically cuts the panels to the preset length during continuous production, ensuring clean edges without burrs and maintaining high-speed output (8-10 meters/minute).
- Space & Cost Efficiency: By combining two machines into one footprint, it optimizes workshop layout, reduces labor costs, and lowers energy consumption, offering an exceptional ROI for overseas buyers.
