Custom Hydraulic Presses
HEMSUN ENGG. INDUSTRIES manufactures heavy-duty Custom Hydraulic Presses across 4-pillar, H-frame, and C-frame configurations at our Dahegam (Gujarat) works. Explore standard models and custom builds below.
Working principle and engineering architecture
The hydraulic engineering behind Custom Hydraulic Presses utilizes closed-loop proportional pressure and flow control, high-flow prefill valves for rapid approach, smooth micro-speed forming transitions, electronic decompression shock dampening, and bottom cushion/ejector cylinders for controlled draw and part ejection.
Variable-displacement axial piston pumps equipped with electronic proportional load-sensing match hydraulic output directly to the required tonnage and speed at each stage of the stroke. Regenerative rapid-advance circuits shorten cycle times by up to 40%, while stepped decompression manifolds eliminate hydraulic line shock and hydraulic water-hammer during full-force reversals. For deep-drawing lines, the bottom cushion cylinder features independently programmable blank-holding pressure curves to eliminate wrinkling and tearing in complex sheet geometries.
Types & Configurations We Build
Sizing and capacity calculations
Custom Hydraulic Presses delivers rigid frame stability, smooth proportional hydraulic force delivery, and programmable stroke regulation for heavy industrial metalworking and component manufacturing. Built with stress-relieved steel plates and precision ground column guides, our hydraulic presses eliminate structural deflection under full rated tonnage across multi-shift production environments.
Sizing & Tonnage Calculations:
Hydraulic press capacity for forming and drawing operations is calculated from material yield strength, perimeter length, and sheet thickness:
Formula: Press Force (Ton) = (Forming Perimeter in mm × Thickness in mm × Shear Strength in N/mm² / 9810) × 1.25
Example: For a stainless steel deep-draw component with 600 mm draw perimeter and 2.5 mm thickness in SS-304 (Shear Strength = 450 N/mm²), required capacity is 86 Ton forming + 40 Ton cushion cylinder = 150 Ton Press.

Procurement and tooling selection guide
Key engineering considerations when selecting hydraulic presses:
- Frame Style: Choose 4-pillar ground columns for multi-directional access or welded H-frame box structures for high off-center load resistance.
- Hydraulic Drive: Variable-displacement axial piston pump with proportional load-sensing reduces power consumption by up to 50%.
- Cushion & Ejector Integration: Specify bottom hydraulic cushion cylinders with programmable blank-holder pressure profiles for deep drawing.
- Safety & Guarding: Ensure optical safety curtains, dual anti-tie-down buttons, and hydraulic mechanical ram lock-up systems.
