Wemhöner Cover
Original-quality cover manufacturing for Wemhöner membrane presses — compatible, durable, fast.
Wemhöner 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.


Wemhöner membrane presses are known for high pressing force and precise temperature control. We manufacture the pins, covers and wear parts of these presses on our high-precision CNC machines, fully compatible with the originals, preserving the performance and pressing quality of the press.
The cover is critical for membrane press sealing and the press surface. We manufacture worn or leaking covers to original dimensions and material.
