Product Details

Our fully automated Silo Purlin Roll Forming Line is engineered for the high-volume production of precision C-section steel purlins, essential structural components for modern storage silos. This integrated manufacturing system transforms raw steel coils into finished, ready-to-install C-purlins with exceptional dimensional accuracy and consistent quality, optimizing your silo framing production.

Line Configuration & Process Flow

1. Decoiling & Feeding System

· Heavy-Duty Decoiler: Accommodates coil weights up to 10 tons with motorized expansion mandrel
· Automatic Coil Car: Facilitates easy loading and changeover
· Pre-Leveling Unit: Multi-roll straightener ensures flat, uniform material entry

2. Pre-Punching & Notching Station (Optional)

· PLC-controlled hydraulic punching system
· Creates accurate bolt holes, service openings, and connection notches
· Programmable for custom hole patterns without interrupting the forming process

3. Precision Roll Forming Section

· Progressive Forming: 10-16 forming stands gradually shape the profile
· High-Grade Roller Dies: Manufactured from alloy steel (Cr12, 12CrMo), hardened and ground for durability
· Quick-Change Design: Facilitates profile/size changeover within 30-60 minutes

4. Cutting & Output System

· Computerized Flying Cut: Hydraulic or servo-driven shear for burr-free cutting
· Automatic Stacker: Counts and bundles finished purlins for efficient handling

Core Advantages & Features

① Superior Product Quality

· Consistent profile geometry ensures easy, secure assembly on-site
· High-strength design maximizes load-bearing capacity for silo cladding
· Clean, precise pre-punching eliminates secondary drilling work

② High Production Efficiency

Frequently Asked Questions

Successful FAT of a Silo Wall Panel Line for Major Indian Manufacturer

Project Case Study: Successful FAT of a Silo Sidewall Production Line Major Indian Manufacturer

Client: A leading silo manufacturing company based in Pune, India
Supplier:BEN THOMAS Machinery Co., Ltd.
Project:Factory Acceptance Test (FAT) for a Fully-Automated Corrugated Silo Wall Panel Production Line
FAT Date:March 2024

1. Client Challenge & Project Objective
Our client,a prominent player in India’s agricultural and industrial storage sector, faced challenges in meeting the surging demand for large-diameter silos. Their existing fabrication process for curved wall panels was labor-intensive, slow, and resulted in inconsistent quality, affecting onsite assembly speed and final silo integrity. They commissioned BEN THOMAS to deliver a complete, automated solution that would guarantee high output, exceptional dimensional accuracy, and robust construction for long-term reliability.

2. The BEN THOMAS Solution
BEN THOMAS engineered a heavy-duty, PLC-controlled corrugation shaping line specifically for high-volume production of corrugated silo wall panels.

Key Line Features:

· High-Precision Corrugation Shaping Forming System: Equipped with hardened tooling to form precise, repeatable corrugation profiles from galvanized steel coils (1mm to 4mm thickness).
· Integrated Punching System: For simultaneous, accurate piercing of bolt holes, lugs, and ladder attachment points in a single pass.
· PLC-Driven Variable-Radius Curving Unit: A standout feature allowing automatic, seamless curvature of panels to various diameters (from 4m to 30m+) without manual adjustment or template changes.
· Automatic Length Measurement & Cutting: Ensured each panel was cut to exact length with ±1mm tolerance.
· Complete Auxiliary Package: Included heavy-duty decoiler, precision leveller, run-out conveyor, and automatic stacking system for finished panels.

3. The Factory Acceptance Test: A Rigorous Validation
A 6-member technical delegation from the client visited the BENTHOMAS factory for a comprehensive 4-day FAT.

· Phase 1: Technical Documentation & Static Inspection. The client’s engineers meticulously reviewed all mechanical drawings, electrical schematics, and component certifications. They inspected the line’s build quality, weld integrity, and major branded components (Siemens PLC, Schneider electrics, etc.).
· Phase 2: Dynamic Dry & Wet Run. The core of the FAT involved multiple production runs using client-provided material.
1. Dry Run: All safety functions, emergency stops, and automatic sequences were tested without material.
2. Wet Run with Target Materials: The line processed several coils at incremental speeds (up to 25 meters per minute). The client team performed real-time quality checks on randomly selected panels, verifying:
· Profile geometry and consistency.
· Hole pattern positioning accuracy.
· Panel length and curvature radius against their specific silo design files.
· Surface finish quality (no scratches or deformation).
· Phase 3: Training & Final Sign-off. BEN THOMAS engineers provided hands-on operational and maintenance training. After addressing all queries and a final review meeting, the client’s Project Manager officially signed the FAT Certificate, confirming the line fully met all contractual performance and quality specifications.

4. Results & Client Endorsement

· Proven Performance: The line exceeded the guaranteed output rate by 12%, achieving a stable production speed of 28 m/min for standard panels.
· Unmatched Accuracy: All dimensional checks confirmed tolerance levels superior to industry standards, ensuring leak-proof, fast onsite assembly.
· Seamless Integration: The line’s PLC interface was praised for its user-friendliness, allowing quick changeovers between different panel specifications.

Client Feedback:
“The BEN THOMAS team demonstrated profound expertise and a cooperative spirit throughout the FAT. The line’s performance, particularly the accuracy of the automatic curving unit, has convinced us of its capability to revolutionize our production efficiency. This investment is a strategic move to enhance our market leadership, and we are confident in the long-term partnership with BEN THOMAS.”
— Director of Operations, Client Company
