Plywood & Woodworking Presses
HEMSUN ENGG. INDUSTRIES manufactures heavy-duty Plywood & Woodworking Presses and multi-daylight hydraulic hot presses at our Dahegam (Gujarat) works. Browse daylight configurations and platen dimensions below.
Working principle and engineering architecture
The hydraulic mechanism employs synchronized multi-ram circuits powered by low-noise axial piston pumps and high-flow prefill valves. Operating at capacities of 280 Ton, 400 Ton, 640 Ton, and 800 Ton with 300 mm stroke and 100 mm daylight gaps, the press executes rapid closing, controlled pressure ramp-up, and programmable hot-pressing dwell cycles (120 to 240 seconds at 110°C–160°C). Multi-zone steam, thermal oil, or electric platen heating guarantees temperature uniformity within ±2°C across every daylight.
Hydraulic synchronization across all 8 cylinders is maintained via matched manifold valving and heavy-duty rack-and-pinion mechanical equalizing guides. This ensures platens remain perfectly parallel during full-tonnage closing, preventing resin migration and board taper. Automatic breathing (degassing) logic allows steam and volatile gases to vent during the critical cure window, yielding flat, blister-free boards conforming to IS:303 and IS:710 quality benchmarks.
Types & Configurations We Build
Sizing and capacity calculations
Plywood & Woodworking Presses is engineered with heavy-duty multi-cylinder architecture (standard 8-cylinder configurations with 125 mm ram bore) to ensure even specific pressure across the entire 8'×4', 9'×4', 11'×4', or 13'×4' platen surface. Built for heavy timber veneers, commercial and marine grade plywood, flush doors, blockboard, and decorative laminates, our presses eliminate core gaps, bubbling, and thickness variation under sustained heat and tonnage.
Sizing & Tonnage Calculations:
To size a plywood hot press, total tonnage is calculated from platen working area and required specific pressure (typically 10 to 18 kg/cm² for hardwood plywood and 8 to 14 kg/cm² for softwood veneers):
Formula: Required Tonnage (Ton) = (Platen Length in cm × Platen Width in cm × Specific Pressure in kg/cm² / 1000) × 1.15
Example: For a standard 8'×4' platen (250 × 130 cm = 32,500 cm²) pressing commercial plywood at 15 kg/cm², required press capacity is 560 Ton to 640 Ton across an 8-cylinder hydraulic bank.

Procurement and tooling selection guide
Key technical criteria when selecting plywood presses:
- Number of Daylights: Choose 5, 10, 15, 20, or 24 daylights matching required daily panel capacity.
- Platen Construction: Precision-drilled solid steel platens with serpentine thermal channels for steam or hot oil circulation.
- Cylinder Synchronization: 8-cylinder bank with 125 mm ground rams ensures zero platen deflection over 8'×4' to 13'×4' spans.
- Hydraulic Automation: PLC-controlled auto-breathing (degassing) cycles to vent steam and glue volatiles.
- Loading Automation: Manual push-in or motorized multi-tier simultaneous automatic cage loaders and unloaders.
