Hydraulic Plate Rolling Machine — Precision Rolling with Heavy-Duty Hydraulics

Monotech Engineers Pvt. Ltd. presents the Scrap Hydraulic Plate Rolling Machine engineered for accurate, repeatable rolling of plates and scrap sheets into cylinders, cones, and curved profiles in recycling yards, fabrication shops, and service centers. A rigid welded frame, induction‑hardened rolls, and high‑pressure hydraulics deliver consistent curvature with precise pre‑bend and cone‑forming control, supporting faster fit‑up and less rework on variable stock. Available in working widths from 1000–3000 mm and thickness capacities from 3–25 mm (MS), with custom builds beyond these ranges—including stainless and abrasive scrap duty—the system offers optional 4‑roll pre‑pinch and cone attachments to minimize edge flats and weld gaps across diverse applications.

Design & Construction

Hydraulic Architecture:
High‑pressure hydraulic power pack with proportional valves for smooth force and speed modulation, enabling controlled pre-bending and rolling across varying scrap thicknesses and materials.
Roll Configuration:
Flexible setup as 3‑roll initial pinch, 3‑roll pyramid, or 4‑roll pre‑pinch. Rolls are alloy-steel, precision-ground, induction-hardened, with optional crowning to maintain roundness and reduce flats.
Frame & Bearings:
Stress‑relieved welded frame with heavy guideways, spherical roller bearings, and labyrinth seals to withstand deflection and contamination in dusty yard conditions.
Positioning:
Hydraulic side‑roll cylinders with linear scales or encoders. Synchronized roll movement maintains repeatable radii and minimizes edge flats through precise side‑roll travel.
Controls:
Pendant or fixed panel with pressure/readout gauges, digital roll position display, inch/jog and auto cycles, emergency stop, and safety interlocks for consolidated control and operator safety.
Finish & Protection:
Industrial coatings, guarded drive areas, and centralized lubrication points for long-term durability and simplified routine maintenance in multi‑shift operations.

What Makes Our Design Unique?

High‑Force Pre‑Bending:
4‑roll hydraulic platform enables true double pre‑pinch at both edges, improving roundness near the seam and minimizing weld gaps on thicker or variable plates.
Precision Radius Control:
Proportional hydraulics with linear feedback ensures smooth, repeatable side‑roll motion for consistent curvature across the sheet length.
Power Under Load:
High‑torque hydraulic drives sustain rolling speed and traction under varying thickness, preventing stalling or scuffing and maintaining surface quality.
Built for Harsh Duty:
Hardened rolls, wear strips, and dust‑sealed bearings safeguard critical components, extending service life in abrasive scrap environments.
Maintenance‑Friendly:
Cartridge valve manifolds, advanced filtration, and easy access to cylinders and guides streamline servicing and reduce downtime during inspections.

Key Features & Accessories

Performance-driven productivity

Variable rolling speed through flow-controlled hydraulics handles thin-to-heavy gauges with smooth ramp-up/ramp-down for precise seam alignment and reduced flats.
Digital position presets with return-to-zero accelerate repeat setups and improve consistency across shifts and operators.
Safety systems include over-pressure reliefs, nip-area safety ropes, dual-channel E‑stop, door/guard interlocks, and load‑holding valves on cylinders for robust protection and controlled stops.
Continuous‑duty hydraulics with dedicated cooling and fine filtration sustain long runs and stable performance across temperatures and workloads.

Optional accessories

Cone-Rolling Attachment: Lateral roll skew with programmable taper presets forms controlled tapers consistently, cutting rework and trial passes.
Material Handling Supports: Lateral/overhead supports and motorized infeed/outfeed roller tables stabilize large diameters, improving feed alignment and throughput.
PLC/HMI Control Suite: Recipe fields for radius, thickness, and width with part counters, alarm history, and maintenance reminders standardize runs and documentation.
Special Roll Finishes: Extra‑hardened or chrome‑plated rolls handle stainless or rusted scrap; optional knurl assist (where allowed) increases traction on challenging surfaces

Control & Handling

HMI Workflows: User-friendly interface with material selection and recipe management for thickness, yield, crown, passes, and speed. Live charts track load, flatness, and energy use, with alarm history and maintenance scheduling.
Assisted Setup: Auto-recommendations for crown and penetration based on material properties; teach mode stores proven parameters for quick reuse.
Recipe Management: Pre-set and recallable material recipes ensure consistency and reduce setup time.
Remote Monitoring: Secure connectivity for live diagnostics, alarm logs, and predictive maintenance alerts.
Training & SOPs: On-site commissioning, safety sessions, operator/maintenance SOPs, and QA documentation templates ensure safe, consistent adoption.
Error-proofing & Safety: Interlocks, guided workflows, and alarm-driven prompts prevent operator errors and material damage.
Data and Analytics: Automatic logging of runs, deviations, and KPIs supports quality control and process optimization.
Operator Ergonomics: Intuitive multilingual touch interface with simplified navigation reduces fatigue and error
