The PFM SCREEN pre-press and ventilation belts are designed for MDF and particleboard manufacturing, ensuring efficient deaeration and uniform pre-compression. With a stable structure, antistatic properties, high chemical and abrasion resistance, and quick splice options, they enhance product quality, reduce downtime, and are ideal for modern continuous pre-press systems.
Description
The PFM SCREEN Pre-press and Ventilation Belts are specialized solutions designed to enhance the manufacturing process of MDF (Medium-Density Fiberboard) and particleboard. These belts play a critical role during the pre-press phase by ensuring efficient ventilation and uniform pre-compression of fiber mats or chip mats.
In modern production facilities, the spread fiber mat or chip mat must undergo precise deaeration to prevent air pockets that can compromise the final product's quality. The PFM SCREEN belts achieve this by expelling air effectively while avoiding lateral displacement of the wood material. Their permeable fabric structure, with mesh sizes tailored to specific wood materials, ensures an optimal balance between ventilation performance and chip geometry.
To further enhance operational safety and performance, the belts incorporate copper or carbon threads woven into the polyester yarn. This feature ensures permanent electrostatic discharge in compliance with Atex standards, eliminating risks of sparks or adhesion issues. The belts’ robust construction, featuring sealed edges and a stable fabric structure, guarantees long-lasting performance and minimal maintenance. Additionally, their compatibility with continuous pre-press systems ensures the fiber or chip mats remain compressed and stable, reducing the risk of spring-back effects before entering the main press.
PFM SCREEN ventilation belts deliver unparalleled productivity improvements through high airflow rates, robust durability, and superior chemical resistance. These features make them indispensable for manufacturers seeking to optimize production efficiency and product quality.
