Polyurethane Frame Perforated Plate – A Dual Guarantee of Strength and Durability

The polyurethane frame perforated plate consists of a polyurethane frame and an internal steel perforated plate. This construction enhances the overall strength of the screen while providing increased flexibility to absorb impact and reduce operational noise. Uniform perforations facilitate efficient separation and minimize the risk of clogging or blinding, ensuring smooth operation throughout the screening process.

QIUSUO provides polyurethane frame perforated plates in a wide range of specifications and aperture sizes. To better accommodate your requirements, we offer customized solutions tailored to your exact needs.
