The Often-Ignored Phase of Production

Many buyers focus their capital solely on the hydraulic presses but underinvest in raw material preparation.

If wood particles are improperly sized, or if MDI glue is unevenly distributed, the best press in the world cannot save the final pallet. The front-end dictates the success of the back-end.

EMP Hammer & Blending Systems

Core Technology

Common Preparation Failures

  • Hardware Destruction: Wood waste containing scrap metal destroying the hammer mill rotor instantly due to absolute lack of magnetic screening.
  • Resin Waste: Gravity blending wasting massive amounts of expensive MDI glue while still leaving structural "dry-spots" that fail under forklift load.
  • Customization Traps: Assuming hot-press molds are generic, resulting in long 4-month waits for non-standard pallet specifications.

Our auxiliary line guarantees that your input waste stream translates to perfectly interwoven, fully coated fiber, pressed by indestructible tooling.

  • Crushing & Sizing (≤5mm): Utilizes high-carbon impact steel to shatter wood along the grain. This produces a needle-like structure that safely filters through 3-5mm screens. Integrated neodymium magnets strip out nails before impact.
  • Continuous Atomized Blending: Uses high-speed rotary action and precise metering pumps to coat fibers in a micro-mist of resin, strictly locking MDI usage precisely to the 5-8% dry-weight ratio.
  • H13 Tool Steel Molds: Precision CNC-machined dies built to withstand 180°C to 220°C continuously, delivering over 100,000 flawless strokes with rapid 2.5-4 hour changeovers.

A correctly dimensioned preparation line removes the bottleneck placed on your automated or semi-automated press systems.

Raw Material Audit & System Sizing

Preparation equipment must be precisely scaled to your raw material reality. Provide photos of your wood waste stream, debris profile, and factory voltage. We will supply a tailored engineering list.
