UHMWPE Forming Board
This UHMWPE drainage element is designed to serve various industrial applications. These UHMWPE forming boards are primarily used for paper industry purposes. UHMWPE machined parts are known for their wear resistance and ability to work well in moist environments. The high end engineered plastic component is cost effective and has a long working life.
Features of the UHMWPE Forming Board
1. Custom fitted to each machine
2. High inertial strength for vibration-free operation
3. 316L stainless steel external construction
4. Free discharge of doctored water
5. T-bar mounting provides the flexibility to control the cover opening without removing the fabric
6. Multiple T-bar positions are spaced to match table pulse frequencies
7. Horizontally and vertically adjustable custom designed mounts provided
8. Complete adjustability to accept jet impingement
