Orma Cover
Original-quality cover manufacturing for Orma membrane presses — compatible, durable, fast.
Orma Cover Manufacturing
Membrane press covers are the parts that provide vacuum and pressing sealing. We manufacture worn covers, or those with a degraded gasket surface, from durable material compatible with the original, restoring sealing and pressing efficiency.


We offer pin and spare-part solutions for Orma membrane presses. We manufacture worn parts that need replacing economically, durably and compatibly, shortening supply time and minimizing production downtime.
The cover is critical for membrane press sealing and the press surface. We manufacture worn or leaking covers to original dimensions and material.
