Product Description
The forming board, foils, vacuum box cover are advanced ceramic dewatering elements designed to enhance paper production efficiency and improve the longevity of forming wires in medium- and high-speed paper machines. These components combine precision engineering and high-quality materials to deliver optimal dewatering, sheet formation, and operational reliability.
Each element, crafted from wear-resistant ceramic with up to 99.8% alumina purity, offers exceptional durability. The seamless segments ensure smooth operation in the machine direction, reducing wear and enhancing performance. Tailored to suit various paper machine configurations, these elements are ideal for gap formers and Fourdrinier machines operating at different speeds.
Product Advantage
