20 Daylight Plywood Hot Press

20 Daylight Plywood Hot Press — process notes

Our 20 Daylight Plywood Hot Press production unit combines 790 Ton of rigid 4-column clamping force with specialized hydraulic circuitry designed for commercial & marine grade plywood boards in dimensions up to 20 Daylights (21 Platens, 100 mm Daylight Gap, 8' × 4'). The primary cylinder executes multi-stage compaction: fast ram approach, precision powder pre-compaction, and a sustained dwell phase of 38 seconds to bleed out microscopic air pockets. Following compaction, smooth electronic decompression takes place over 3–5 seconds before lower knock-out pins elevate the green preform for automated pickup.

20 Daylight Plywood Hot Press — material behaviour

Calibrated specifically for compaction of timber veneers, core sheets, resin-glued wood plies & laminates, the hydraulic ram ensures steady force application to achieve optimal particle interlocking. Generous bolster daylight accommodates large powder fill heights without compromising platen alignment under continuous multi-shift operations.

20 Daylight Plywood Hot Press — tooling design

Precision-ground tie pillars and bronze guide sleeves ensure exact tooling concentricity. Cavity inserts for commercial & marine grade plywood boards are manufactured from premium cold-work die steel with micro-lapped bores to minimize surface friction during compaction.

20 Daylight Plywood Hot Press — sizing and selection

For customized quotation of this 790 Ton 20 Daylight Plywood Hot Press, please provide part CAD files, material filler percentage, and target shift output. We calculate hydraulic cylinder dimensions, bolster clearances, and power pack ratings to ensure optimal production efficiency.

20 Daylight Plywood Hot Press — quality checks

Our quality protocol includes laser-verified platen parallelism under full tonnage, digital pressure transducer calibration, and test pressing of witness samples before packing.

20 Daylight Plywood Hot Press — installation and commissioning

Delivered with full engineering documentation: foundation layout, electrical schematics, hydraulic maintenance guides, and spare seal kits. Experienced HEMSUN technicians travel to your plant for turnkey setup and operator training.

20 Daylight Plywood Hot Press — export and lead time

We provide full export handling with certified seaworthy timber packing, rust-inhibiting VCI film, destination-specific electricals (415V/50Hz), and complete shipping documentation.

20 Daylight Plywood Hot Press — maintenance and spares

Preventative maintenance includes 1,000-hour oil filtration checks, regular bronze bushing lubrication, and periodic hydraulic cylinder pressure testing. Spare seal kits, solenoid cartridges, and replacement filter elements are available directly from HEMSUN.

20 Daylight Plywood Hot Press — safety notes

Operator safety is ensured by Category 4 optical safety light curtains across the front working area, two-hand anti-tie-down cycle start pushbuttons, dual hydraulic safety drop-prevention valves, and mushroom-head emergency stop switches integrated with the main PLC control panel.
