04 — Product Application

Where Saw Dust Wood Chips Compressed Plywood Boards Are Used

Compressed plywood and wood chip boards serve as high-density, structural alternatives to traditional timber and plywood panels in industrial packaging, furniture, and construction. Their superior mechanical strength, uniform density, and smooth surface finish make them ideal for heavy-duty structural applications and eco-friendly manufacturing.

Industry Applications

Compressed wood chip and sawdust boards are widely used across industrial packaging, commercial furniture manufacturing, building construction, and logistics warehousing sectors. Converting low-cost timber offcuts and wood waste into high-density composite panels enables industries to eliminate solid timber consumption, reduce carbon footprints, prevent pest delays, and achieve sustainable structural manufacturing.

Heavy-Duty Packaging, Cargo Boxes, and Transport Crates

Provides high impact resistance and load-bearing strength necessary for protecting heavy industrial machinery, automotive parts, and bulk export goods. Resists structural cracking and warping under extreme environmental conditions, ensuring safe long-distance transit across global supply chains

Industrial Furniture, Commercial Cabinetry, and Modular Workstations

Offers a smooth, high-density surface ideal for laminating, veneering, or direct painting in office furniture and modular cabinetry production. Maintains excellent screw-holding power and edge stability, preventing joint loosening or panel sagging under heavy commercial use.

Building Construction, Concrete Formwork, and Wall Paneling

Delivers excellent moisture resistance and structural flatness required for temporary site hoarding, sub-flooring, and architectural interior paneling. Replaces expensive solid wood and standard plywood sheets, offering a fire-retardant and termite-resistant alternative for modern construction projects.

05 — Key Advantages

Why Choose the 1250-Ton Sinter Hydraulic Press

The 1250-Ton Sinter Hydraulic Press provides heavy thermal compression force and multi-zone temperature regulation engineered for manufacturing dense wood-composite panels. Its multi-stage steam degassing, rigid four-pillar guidance, and automated stripping system ensure flat, warp-free, high-strength boards with superior screw-holding capability.

Technical & Commercial Benefits

01

Massive 1250-Ton Tonnage Delivering High-Density Consolidation

Generates 1250 tons of continuous hydraulic pressure to consolidate loose sawdust and wood chip mats into dense, rigid structural boards. High compaction force eliminates internal air pockets, interlocking wood fibers to achieve high-strength, plywood-grade mechanical properties.

02

Precision Multi-Zone Thermal Oil Heating for Uniform Resin Curing

Transfers thermal energy evenly across the large 2500 x 1300 mm platen workspace to fully cure thermosetting synthetic and bio-binders. Balanced thermal distribution eliminates uncured core zones, preventing internal delamination, edge cracking, or surface defects in finished panels.

03

Multi-Stage Decompression Degassing System Preventing Internal Voids

Executes precise micro-decompression pauses during hot pressing to vent high-pressure steam and resin vapor trapped inside thick wood mats. Evacuating steam prevents internal blistering, surface blowing, and structural weakness, guaranteeing high panel integrity.

04

Rigid Pre-Stressed Four-Column Architecture Ensuring Parallelism

The heavy-duty four-column frame absorbs continuous high tonnage without structural deflection, maintaining precise platen parallelism under thermal stress. Absolute alignment guarantees uniform board thickness, consistent core density, and flat surfaces across large footprints.

05

Integrated High-Force Stripping System for Non-Destructive Demolding

Features an 800 kN bottom ejection and edge-stripping mechanism paired with pneumatic assist jets to smoothly lift hot, cured composite sheets. Synchronized extraction prevents panel cracking, corner chipping, and surface tearing during rapid automated material discharge cycles.

06

Low-Cost Waste Conversion Yielding High-Margin Composite Panels

Transforms low-value timber offcuts, sawdust, and screened wood chips into high-value engineered plywood and particleboard sheets. Utilizing abundant agricultural and forestry wood waste significantly lowers raw material expenses while producing sustainable, eco-friendly building materials.
