Core Components & Technical Features
1. High-Precision CNC Peeling Lathe
Features: A high-rigidity bed and precision spindle ensure dynamic stability during high-speed peeling. Equipped with ultra-sharp, wear-resistant blades and a micron-level feed system, it consistently produces ultra-thin veneers with a thickness tolerance within ±0.05mm, guaranteeing quality from the source.
2. Tensioned Veneer Conveying & Intelligent Drying System
Tensioned Conveying: A belt or roller system applies appropriate tension to the veneer ribbon immediately after peeling, preventing folding and wrinkling for smooth transfer to the dryer.
Mesh Belt/Roller Dryer: Utilizes adjustable low-temperature and high-airflow drying specifically for thin veneers. Precise zoning within the dryer controls temperature and humidity, enabling uniform and gradual drying to minimize internal stress and prevent curling.
3. Tension-Free Clipping & Automatic Splicing/Repair System
Tension-Free Clipping: The clipper releases veneer tension at the moment of cutting, ensuring clean, splinter-free edges.
Automatic Splicing: High-precision jointers (longitudinal/cross-feed) seamlessly join smaller veneer sheets into full-size sheets, maximizing material yield.
Automated Repair: Vision systems automatically detect defects like splits and holes, performing precise patching to upgrade veneer quality.
4. Micro-Dosing Gluing & Automated Layup System
Precision 4-Roller Glue Spreader: Precisely controls minimal glue spread (e.g., 100-120g/㎡), ensuring a uniform layer to avoid glue bleed-through and surface contamination while reducing costs.
Robotic Layup Center: Fully-automated robots handle veneer picking, laying, and alignment. Using vacuum cups or belt conveyors, they gently handle veneers, ensuring cross-grain alignment with high precision (up to ±0.5mm), drastically reducing human error.
5. Precision Pre-Pressing & Multi-Stage Hot Press
Pre-Press: Gently compresses the assembled mat to remove air and achieve initial bonding, creating a mat with sufficient handling strength for safe loading into the hot press.
Intelligent Hot Press: The core equipment. Multi-cylinder synchronous pressing technology ensures extremely even pressure distribution. The control system executes complex multi-stage pressure-temperature profiles (e.g., "low pressure - temperature rise - pressure holding - pressure release") at critical curing points to prevent panel crushing while ensuring optimal bond strength. Specially treated platens guarantee exceptional flatness and temperature uniformity, achieving a final thickness tolerance within ±0.2mm for 3mm plywood.
6. Central Intelligent Control System
Integrates PLCs and industrial computers to monitor and record real-time parameters (speed, temperature, pressure, etc.) for each section. Operators can preset and recall production recipes via a touchscreen interface for quick changeovers, ensuring consistent, traceable product quality.
High Yield: Targeted designs minimize breakage and waste during the production of ultra-thin panels.
Exceptional Quality: Output plywood boasts precise thickness, excellent flatness, and stable structure, meeting demands for high-end applications.
High Efficiency: High automation enables continuous operation with high output and reduced reliance on skilled labor.
Energy & Material Saving: Precise gluing and drying systems effectively reduce adhesive and energy consumption.
The ultra-thin 3mm plywood produced by this line is widely used in:
High-End Furniture: Drawer bottoms, cabinet backs, substrates for curved furniture.
Interior Decoration: Wall and ceiling linings, door panels.
Electronics: Back panels or partitions for speakers, TVs, server racks.
Crafts & Packaging: Gift boxes, model making, sports equipment (e.g., skateboard substrates).
