Plywood Pre Press
Plywood Pre Press — Hydraulic Specifications, Platen Clearances & Tooling Dies
Produced in Dahegam, Gandhinagar, Gujarat, India, the Plywood Pre Press (Series HSE-413) delivers reliable high-pressure compaction for pre-pressed plywood veneer stacks. Features 4-column structural rigidity, digital pressure monitoring, shock-free decompression, and turnkey tooling integration for OEM processors.
Applications
- High-volume hot pressing of pre-pressed plywood veneer stacks for plywood and wood panel processing plants (Ref: APP-7613).
- Multi-daylight hydraulic consolidation with synchronized platen heating and automated loading shuttles.
- Thermal bonding of resin-coated veneers under precise temperature and pressure curves.
- Turnkey installation for panel manufacturers with complete hydraulic power pack, boiler piping, and FAT certification.
Plywood Pre Press — process notes
Custom-built for high-yield manufacturing of pre-pressed plywood veneer stacks, this Plywood Pre Press installation delivers 717 Ton of uniaxial compressive force to form Standard 8' × 4' up to 13' × 4' multi-daylight panel envelope workpieces. The hydraulic power pack features high-response proportional cartridge valves that execute a rapid-advance stroke, micro-speed consolidation, and a programmed 69-second dwell curve. Regulated pressure decay guarantees stress-free preform release, while an auxiliary bottom hydraulic cylinder applies smooth ejection force to raise the finished green part without edge chipping or cavity wall friction marks.
Plywood Pre Press — material behaviour
Engineered to handle granular suspension resins and filled grades of timber veneers, core sheets, resin-glued wood plies & laminates, the cylinder stroke and platen guidance maintain strict parallelism. Uniform uniaxial pressure distribution creates isotropic workpieces with high tensile strength and void-free dielectric resistance following oven processing.
Plywood Pre Press — tooling design
Featuring robust tie-bar construction with bronze-bushed sliding platens, the press provides exceptional die guidance. Tooling cavities for pre-pressed plywood veneer stacks incorporate calibrated thermal shrinkage allowances to guarantee accurate finished dimensions.
Plywood Pre Press — sizing and selection
Our application engineers assist in configuring the Plywood Pre Press by determining total projected mould area and compaction tonnage (717 Ton capacity). Send your component technical specifications for an itemized commercial and technical proposal within 24 hours.
Plywood Pre Press — quality checks
Quality assurance procedures cover ultrasonic testing of cylinder forgings, hydraulic pressure endurance runs, platen parallelism validation, and trial component pressing.
Plywood Pre Press — installation and commissioning
We supply comprehensive startup manuals, foundation drawings, electrical wiring diagrams, and spare parts lists. Field engineers provide on-site commissioning and operator instruction for seamless plant integration.
Plywood Pre Press — export and lead time
Fully export-ready, the unit complies with international electrical standards (380V/60Hz) and features seaworthy timber crating with internal rust-inhibiting foil for transit via Mundra or Nhava Sheva container terminals.
Plywood Pre Press — maintenance and spares
Maintenance guidelines recommend hydraulic oil replacement every 2,000 hours (ISO VG 68), daily column greasing through centralized lubrication ports, and annual check of hydraulic valves. Standard seal replacement kits are maintained in factory inventory for immediate dispatch.
Plywood Pre Press — safety notes
Plant safety compliance is ensured by optical safety barriers, two-hand cycle start controls, hydraulic burst-protection valving, and illuminated emergency stop actuators.
