Production Equipment
This production line is designed for an annual output of 50,000 cubic meters of standard plywood. It integrates advanced processes with cost-effective semi-automatic equipment, achieving efficient and stable production from logs to finished plywood. The core equipment of the entire line includes:
![]() | 1. Log Handling Section |
Log Unloader and Haul-In Machine: Uses hydraulic or mechanical methods to unload logs from transport vehicles and convey them orderly to the debarking station.
Debarker: Efficiently removes the bark from logs, ensuring the smoothness and quality of the subsequent veneer and reducing tool wear.
![]() | 2. Veneer Preparation Section |
Veneer Lathe / Peeler: One of the core equipment of the production line. It centers and clamps the debarked log blocks, rotates them at high speed against a sharp blade to continuously peel a ribbon of veneer at a predetermined thickness. It features high precision and stability.
Veneer Clipper: Automatically cuts the continuous veneer ribbon into wet veneer sheets of required dimensions and sorts usable and unusable parts.
![]() | 3. Veneer Drying and Processing Section |
Roller Dryer: Uses high-temperature hot air to quickly and uniformly dry the wet veneer, reducing the moisture content to the range required for the gluing process. The equipment is equipped with temperature and air speed control systems to ensure drying quality.
Veneer Splicer: Splices small-dried veneer sheets or veneer with defects into large full sheets via finger-jointing or lap splicing, improving wood utilization. This process is often manually or semi-automatically assisted.
![]() | 4. Gluing and Layup Section |
Glue Spreader: Another core equipment. Adopts a four-roller or two-roller structure to apply prepared glue (e.g., urea-formaldehyde resin) evenly and quantitatively onto the veneer surface. The machine is equipped with a glue application control system.
Layup Line: A semi-automatic station where operators assemble glued core veneers with unglued face/back veneers into matts according to the required number of piles and grain direction. Equipped with layup tables and a pre-press.
![]() | 5. Hot Pressing Section |
Hot Press: The absolute core equipment of the production line. It uses a multi-opening structure to cure and bond the glue in the matts under high temperature and pressure. Equipped with an advanced PLC control system to precisely control the temperature, pressure, and time profile of the hot plates, ensuring bonding strength and consistent layer quality. Hydraulic or water pressure systems can be selected based on product requirements.
![]() | 6. Finishing Section |
Cooler and Turner: Separates and cools the hot pressed panels to prevent warping and dissipate residual heat.
Cross-Cut and Edge Trimming Saws: Precisely cuts the cooled rough-edged panels to standard sizes, removing irregular edges.
Sander: Typically a double-sided calibrating sander. Finely sands the panel surfaces to remove the pre-cured layer, thickness deviation, and minor defects, obtaining finished panels with uniform thickness and a smooth surface.
Plywood Production Line Process Flow
The core function of a complete plywood production line is to transform raw logs into multi-layered bonded panels through a series of physical and chemical processes. The main production flow is as follows:
1. Log Handling
Debarking: Use a debarker to remove the bark and impurities from the logs, preparing them for peeling and protecting the cutting tools.
Cutting/Bucking: Saw long logs into standard-length blocks based on the required veneer length and raw material conditions.
2. Veneer Production
Soating/Steaming: Soften the log blocks by soaking or steaming them in hot water vats, which facilitates better peeling and reduces splitting.
Peeling: This is a core process. The softened block is mounted on a lathe/peeler and rotated against a sharp blade, continuously peeling it into a long, continuous ribbon of veneer at a predetermined thickness.
Clipping: The continuous veneer ribbon is fed through a clipper, which cuts it into rectangular or square wet veneer sheets according to preset specifications and removes defective sections.
3. Veneer Drying & Grading
Drying: The moisture content of wet veneer is very high. It must be fed into a dryer (usually roller or mesh belt type) where hot air reduces its moisture content to the required range (typically 8%-12%) to prevent mold and ensure bonding strength.
Grading & Patching: Dried veneer is graded based on surface quality (e.g., knots, splits). Defective but usable veneer sheets are repaired using patching machines to improve wood utilization.
4. Gluing & Layup
Gluing: Graded veneers (typically used as core layers) are passed through a glue spreader to evenly coat both surfaces with adhesive (e.g., UF resin, PF resin).
Layup/Assembling: Manual labor or automated systems assemble the glued core veneers with unglued face and back veneers into a complete "mat" according to the required number of piles and grain direction (adjacent layers have perpendicular grains). This is crucial for ensuring the structural strength and preventing warpage.
5. Pre-pressing & Hot Pressing
Cold Pre-pressing: The assembled mat is initially pressed in a cold press to achieve preliminary bonding, making it easier to handle and load into the hot press while preventing misalignment during hot pressing.
Hot Pressing: This is the core process for plywood formation. The mat is loaded into a multi-opening hot press. Under high temperature (e.g., 120-150°C) and high pressure (e.g., 100-150 kg/cm²), the adhesive cures rapidly, firmly bonding the multiple veneer layers together.
6. Finishing
Cooling: The panels exiting the hot press are very hot. They need to be cooled naturally or by a cooler/turner to release internal stress, stabilize their shape, and prevent deformation.
Trimming: Double-end trimming saws cut off the irregular, pressed edges on all four sides of the cooled panel to obtain neat, rectangular boards.
Sanding: The panels are fed through wide-belt sanders for thickness calibration and surface finishing. This process removes the pre-cured layer, thickness variation, and minor defects, resulting in a finished product with uniform thickness and a smooth, flat surface.
Inspecting & Grading: Finally, the finished panels are inspected and graded according to national standards based on their appearance and physical properties before being packaged and stored.
Production Line Features
Semi-Automatic: Achieves automated control in key links like peeling, drying, and hot pressing, while retaining manual operation in links like layup, perfectly balancing investment cost and production efficiency.
High Output & Stability: Equipment selection and cycle design ensure a stable annual production capacity of 50,000 m³.
High Cost-Effectiveness: Employs mature and reliable technology and equipment configuration, offering a high return on investment, particularly suitable for market demands in developing countries.
Flexible Adaptation: The production line can adapt to various wood species (e.g., poplar, eucalyptus, birch) and produce plywood of different specifications and thicknesses.
Annual output of 50,000 cubic meters
![]() | 1. Scale and Level |
Industry Positioning: Significantly larger than small family-run workshops (annual output of a few thousand to 10,000 m³) but smaller than large, fully automated giant factories (annual capacity >100,000 m³). It is a highly practical and competitive scale.
Investment Characteristics: Requires substantial initial investment (equipment, factory, land), but compared to super-large production lines, the entry barrier is lower, and the return on investment is more manageable.
Production Characteristics:
Daily Output: Calculated based on 300 working days per year, the daily output is approximately 167 m³.
Organization: Typically adopts a semi-automated model of "automation in key processes (peeling, drying, hot pressing) + manual assistance (layup, patching, loading/unloading)", which is the mainstream choice in current domestic and international markets.
Product Adaptability: The scale is sufficient to produce various specifications and thicknesses (e.g., common 4-18mm thicknesses), allowing flexibility to respond to market changes. It can steadily supply construction template manufacturers and also produce ordinary plywood for furniture and decoration.
Market Positioning: This capacity is sufficient to become a key supplier in a region, capable of undertaking medium-sized project contracts and export orders while supplying local wholesalers.
![]() | 2. Raw Material Consumption |
Core Raw Material: Logs (Poplar, Eucalyptus, Birch, Okoume, etc.)
Consumption Estimate:
Comprehensive Yield Rate: The process from log to finished plywood involves multiple stages of loss (debarking, peeling, drying, trimming, sanding). The comprehensive yield rate is usually between 50% - 60%. We will use a median value of 55% for calculation.To maintain an annual output of 50,000 m³ of finished product, approximately 90,000 - 100,000 m³ (solid volume) of logs are consumed annually. This necessitates a very stable and reliable log supply source.
![]() | 3. Radiation Range |
3.1 Raw Material Procurement Radius:
Ideal Range: Within 200-300 km. Logs are bulky and heavy, making long-distance transportation extremely costly and a significant profit drain. The factory must be located near the raw material source or a distribution hub.
Maximum Range: If certain precious wood species are not available locally, sourcing from farther away might be necessary, but this would constitute a very small portion of the raw materials.
3.2 Product Sales Radius:
Core Market Circle: Within 500-800 km by road transport. This is the area where the product is most price-competitive. Products can be efficiently distributed to major markets within the province and surrounding provinces via truck transport.
National & Export Markets: Products can be sold nationwide and even overseas (e.g., Middle East, Southeast Asia, Europe, America) via rail or sea. However, beyond the core road transport range, the product's price advantage diminishes, and it must compete based on quality, brand, or special specifications. For a 50,000 m³ capacity, export is an important channel for absorbing capacity and improving profits.
Market Layers: Can simultaneously cover local retail, wholesale in surrounding provinces, national project tenders, and foreign trade exports.
Summary: A 50,000 m³ annual production line is a "capital ship" level project. Its success hinges on: Stable and low-cost raw material supply (localization) + Efficient production management + Flexible and diversified market sales strategy (local, national, international).
