800 Ton Four Column Hydraulic Press for Deep Drawn SS Kitchen Sink

COMPLETE TECHNICAL DATA 

The SM 800 HP is an industrial-grade 800-ton hydraulic press specifically engineered for the high-precision deep drawing of stainless steel kitchen sinks. It combines robust structural rigidity with advanced proportional hydraulics to ensure consistent material flow, minimizing defects and maximizing production efficiency.

Capacity

• Maximum Main Pressing Force: 800 Tons (8000 kN)
• Die Cushion / Blank Holder Force: 250 - 300 Tons

Structural Design

• Heavy-duty, ultrasonically tested welded steel plate construction.
• Thermally stress-relieved to ensure maximum rigidity and near-zero deflection under peak tonnage.

Frame Type

• Heavy-duty 4-Pillar (Column) design or rigid Closed H-Frame.
• Equipped with precision 8-point slide guides for highly accurate ram alignment.

Hydraulic System

• High-performance servo-hydraulic or proportional valve system mounted on a modular manifold.
• Integrated oil cooling and offline filtration system for continuous high-volume operation.

Main Ram Stroke: 800 mm (Adjustable via linear position transducers for varying sink depths).

Working Hydraulic Pressure: Maximum Operating Pressure: 250 Bar (25 MPa).

Daylight Gap:  Maximum Open Height (Bolster plate to ram): 1200 mm.

Approach Speed: Rapid descent speed: ~250 mm/sec.

Pressing / Drawing Speed: Precision-controlled drawing speed: 10 - 20 mm/sec (Optimized for SS material flow).

Return Speed: Rapid retract speed: ~200 mm/sec.

Bed / Platen Size Platen

• Dimensions: 2000 mm x 1500 mm (Customizable based on sink mold dimensions).
• Machined with standard T-slots for secure and rapid die clamping.

Columns

• 4-Pillar Construction (if applicable): Solid forged steel, hard-chrome plated and ground for high wear resistance.
• Diameter: ~250 mm.

Working Envelope

• Front Opening: ~2000 mm for easy operator access.
• Side Opening: ~1500 mm, designed for ergonomic loading, unloading, and maintenance.

Control System

• HMI Touch Screen interface for recipe management, real-time pressure monitoring, and fault diagnostics.

Main Motor Power: 75 kW to 90 kW (High-efficiency IE3 induction motor).

Valves & Hydraulics: Proportional logic manifold valves (e.g., Rexroth, Parker, or Yuken) for precise control of tonnage and speed profiles

Automation

• Pre-wired for seamless robotic loading/unloading integration.
• Centralized automatic lubrication system for all guide points.

Safety Features

• Front and rear photoelectric light curtains.
• Two-hand (dual palm) anti-tiedown push button operation.
• Hydraulic safety anti-fall block and multiple emergency stop (E-Stop) buttons.
