Industrial Raw Particle Board: Zero Lamination Defects & 1,100 N Screw Retention

Eliminate telegraphing bubbles and edge tear-outs on your lamination line. Engineered on a German Dieffenbacher 42m continuous hot-press, Cuzi Raw Particle Board combines 720 kg/m³ diamond-sanded micro-faces for 80g papers with an interlocking structural core that holds screws up to 1,100 N. 100% pre-cleared for US EPA TSCA Title VI and European EN 312 P2.

Engineered 3-Layer Micro-Structure

Unlike lower-grade single-layer boards that suffer from brittle core crumbling and surface pitting, Cuzi Raw Particle Board is formed using a computerized wind-sifting airflow separator. The process deposits micro-fine wood particles (< 0.5mm) onto the top and bottom faces, while interlocking, longer structural flakes (15-25mm) form a resilient core matrix.

Face Layer Density (Top & Bottom 1.5mm): 720 ± 15 kg/m³
Structural Core Matrix Density: 650 ± 20 kg/m³
Sanding Calibrating Tolerance: ±0.20 mm (Steinemann 8-Head)
Moisture Content (EN 322): 7.0% ± 2.0% Calibrated

1. Melamine & HPL Pressing Parameters

The 180-grit diamond-sanded face eliminates surface pitting and resin starvation, allowing high-speed short-cycle presses to achieve perfect thermal fusion:

  • Short-Cycle Melamine Pressing: Temperature 190°C – 210°C; Specific Pressure 2.5 – 3.2 MPa; Pressing Time 16 – 22 seconds.
  • High-Pressure Laminate (HPL) Cold Pressing: Compatible with PVAc (D3/D4) and contact adhesives under 0.5 – 0.8 MPa for 45 – 90 minutes.
  • Natural Wood Veneer Pressing: Low-temperature hot-melt or UF glue at 90°C – 110°C; zero bleed-through due to sealed micro-chip pore density.

2. Automated CNC Sawing & Tooling Specs

To maximize tool life and achieve crisp, chip-free cut edges on automated beam saws and nesting routers:

  • Saw Blade Tooth Profile: Triple Chip Grind (TCG) or Alternate Top Bevel (ATB) with Polycrystalline Diamond (PCD) tips.
  • Cutting Speeds: Rim speed 60 – 80 m/s; Feed speed 15 – 30 m/min; Scoring blade depth 0.5 – 1.0 mm.
  • Pre-Drilling Guidelines: Drill pilot holes to 70-80% of screw core diameter (e.g. 3.0mm pilot for 4.0mm wood screws, 5.0mm pilot for 7.0mm confirmat bolts).

Frequently Asked Questions (B2B Buyer FAQ)

Authoritative direct answers on container minimums, standards compliance, and fabrication tolerances.

Our 18mm raw particle board features a calibrated 3-layer vertical density gradient: outer micro-fine layers reach 720 ± 15 kg/m³ to provide an ultra-smooth, pore-sealed surface for bubble-free paper lamination, while the structural core matrix is 650 ± 20 kg/m³ for high screw retention. Thickness tolerance is strictly controlled within ±0.20mm via inline Swiss Steinemann 8-head laser calibrated sanding.

Every production batch uses advanced low-emission MDI and E0 urea-melamine resin systems. Our in-house ISO 17025 accredited laboratory conducts daily desiccator testing, backed by quarterly third-party certifier (TPC) large chamber tests (ASTM E1333) verified by SGS and Intertek to guarantee emissions strictly below 0.05 ppm (well beneath the 0.09 ppm federal legal limit).

Yes. The 180-grit diamond-sanded micro-chip face is engineered specifically as a primary substrate for short-cycle melamine paper pressing (190-210°C, 2.5-3.5 MPa), high-pressure laminate (HPL) cold pressing, and natural wood veneer vacuum pressing with zero surface telegraphing or air bubble delamination. For a ready-finished surface, compare melamine faced chipboard. Include the intended facing material and finishing process when requesting raw-board samples.

Our standard minimum order quantity (MOQ) is one 20GP (approx. 440 sheets 18mm / 8 pallets) or one 40HQ container (approx. 880 sheets 18mm / 16 pallets), yielding approximately 47.15 m³ net timber volume and utilizing the maximum highway payload limit of 26.9 metric tons. For your loading quotation, list the sheet count for each size and thickness, destination port and preferred delivery terms. Send your product mix for a quotation.

We recommend Polycrystalline Diamond (PCD) or micro-grain tungsten carbide (TCT) saw blades with Alternate Top Bevel (ATB) or Triple Chip Grind (TCG) tooth geometry. Optimum cutting rim speed is 60 to 80 m/s with feed speeds of 15 to 30 m/min. Sizing lines should utilize an independent bottom scoring saw running at 0.5-1.0mm depth to prevent bottom face chip-out.

Because the core consists of interlocking flat pine flakes bonded under continuous heat and pressure (internal bond ≥ 0.45 N/mm²), Cuzi Particle Board provides face screw pull-out resistance ≥ 1100 N and edge resistance ≥ 850 N (EN 320). Pre-drilling pilot holes at 70-80% of screw core diameter ensures crack-free confirmat (7.0×50mm) and 15mm Minifix cam-lock assembly.

Sheets are stacked on heavy-duty ISPM-15 heat-treated timber pallets with bottom and top high-density cover boards. The bundle is wrapped in 0.08mm moisture-barrier polyethylene film, reinforced with 4mm solid particle board edge protectors along all 12 perimeter edges, and bound with 6 to 8 longitudinal and transverse high-tensile steel straps.

Every shipment includes a commercial invoice with EPA TSCA Title VI statement, packing list, bill of lading, Certificate of Origin, batch-specific ISO 17025 Certificate of Analysis (COA), phytosanitary treatment certificate, and optional FSC Mix Credit Chain of Custody transfer documentation for LEED v4 green building submittals. Identify the documents required for your destination market and project in the inquiry. Use the certifications page to prepare your document request.
