Hydraulic Presses by Tonnage
HEMSUN ENGG. INDUSTRIES manufactures industrial hydraulic presses, compression moulding machines, and special purpose machinery (SPM) at our Dahegam (Gujarat) facility. Explore machines categorized by application, material, and tonnage below.
Hydraulic Presses By Tonnage — Working Principle & Engineering Architecture
The engineering architecture across our machinery range incorporates heavy-duty normalized steel frames (4-pillar ground columns, fabricated H-frame box structures, and C-frame gap beds) combined with closed-loop proportional hydraulics. Low-noise variable-displacement axial piston pumps deliver smooth rapid-advance strokes, micro-speed compaction transitions, and programmable pressure dwell cycles (holding sustained forces from 200 to 350 bar). Stepped electronic decompression profiles eliminate hydraulic line shock and prevent preform shear cracking upon mould opening.
Each machine category integrates specialized engineering sub-systems tailored to specific manufacturing processes: multi-cylinder synchronized hydraulic banks for multi-daylight plywood hot presses, programmable micro-breathing (degassing) cycles for friction materials and Bakelite, bottom cushion cylinders with proportional blank-holder pressure curves for deep-drawing, and high-pressure intensifier manifolds for special purpose testing rigs. Siemens and Schneider PLC touchscreen interfaces provide multi-recipe storage, real-time tonnage monitoring, and digital cycle logging. Precision manifold blocks eliminate external piping, minimizing potential oil leak points.

Hydraulic Presses By Tonnage — Sizing & Capacity Calculations
Selecting the optimal hydraulic press requires precisely matching your component geometry and production rate with appropriate structural frame architectures, hydraulic circuit dynamics, and control automation. Whether your facility requires multi-action deep drawing for automotive sheet metal stampings, high-tonnage powder compaction for PTFE billets and technical ceramics, multi-daylight heated platen compression for plywood panels and friction materials, or high-speed scrap baling and forging, HEMSUN manufactures standard and custom-engineered presses from 10 Ton to 1,000 Ton. Every machine is designed with finite element analysis (FEA) to ensure frame stress concentration stays well below elastic limits under continuous full-tonnage duty.
Sizing & Tonnage Calculations:
Hydraulic press sizing follows direct process engineering calculations based on total projected cavity area, forming perimeter, or panel dimensions:
Formula: Required Press Capacity (Ton) = (Tooling Bolster Area in cm² × Specific Pressure in kg/cm² / 1000) × 1.20 Safety Factor
Example: Compacting a 300 mm × 300 mm composite slab (900 cm²) at 300 kg/cm² requires a 324 Ton to 400 Ton hydraulic press cell with appropriate platen daylight and ejector stroke.

Hydraulic Presses By Tonnage — Procurement & Tooling Selection Guide
Systematic framework for evaluating engineering requirements:
- Define Process Geometry: Determine platen bolster envelope, daylight gap, stroke depth, and part loading direction (front-to-back vs left-to-right shuttle).
- Select Hydraulic Architecture: Variable-displacement axial piston pumps reduce idle power consumption by up to 50% compared to fixed gear circuits.
- Determine Automation Level: Choose manual lever control for toolroom repair, semi-automatic PLC touchscreen cycles for batch production, or fully automated robotic pick-and-place lines.
- Tooling & Die Integration: Ensure bolster platens include standardized DIN 650 T-slots and that die cavities are vacuum-hardened AISI D2/H13 tool steel.
- Safety Compliance & FAT: Verify Category-4 optical light curtains, dual anti-tie-down safety buttons, and factory acceptance witness testing prior to dispatch.
