Custom UHMWPE Suction Box Cover Panels are wear-resistant plastic panels used on paper machine suction boxes, vacuum boxes and dewatering sections. They are designed to support the moving fabric or wire while allowing water to pass through slots or openings during the dewatering process.
Made from UHMWPE, also known as Ultra-High Molecular Weight Polyethylene, these suction box covers provide low friction, good wear resistance, impact resistance and smooth sliding performance. Compared with metal or traditional cover materials, UHMWPE helps reduce fabric wear, lower running resistance and improve service life in continuous paper machine operation.
The panels can be machined with straight slots, diagonal slots, chevron patterns, long grooves or custom opening designs according to the paper machine structure and dewatering requirements.

Why Choose UHMWPE Suction Box Covers?
In paper machine operation, the fabric or wire moves continuously over the suction box cover. The cover surface needs to be smooth, wear-resistant and stable to reduce friction and prevent excessive fabric damage.
UHMWPE is suitable for this working condition because it has a low coefficient of friction, good wear resistance and strong moisture resistance. It can help reduce operating resistance, extend fabric service life and support stable dewatering performance.
