High-Performance UHMWPE Suction Box Cover/Filter Plate for Papermaking Equipment

Papermaking is an important industry in many countries and it requires a variety of specialized tools and equipment to ensure efficient production. One of the most important pieces of equipment in a papermaking plant is the suction box cover/filter plate. This plate is responsible for filtering out dirt and debris from the water used in the papermaking process, ensuring that only clean water is used in the process.

UHMWPE (ultra-high molecular weight polyethylene) material is a type of plastic that has become increasingly popular in the papermaking industry due to its strength, durability, and cost-effectiveness. More and more clients request for UHMWPE suction box cover plates.

In this blog, we’ll take a closer look at the advantages of using UHMWPE suction box covers/filter plates in the papermaking process.
