Our seal base - your solution

Claw / new seal base

Cutting a window profile during manufacture puts particular stress on the seal base.

The newly developed seal base from Semperit – which can be used with almost all seal geometries – does not only significantly increase the durability against displacement achieved to date by up to 35% in comparison to conventional geometries, but also reduces mounting force by up to 50%.

This seal base, which we already applied a patent for, has already been used in practice very successfully for around one year.

Informed development, supported by the finite element method (FEM) and a series of tests carried out in Semperit’s in-house test centre, has directly and specifically improved manufacturing processes with targeted optimization of design criteria for mandrels, inner walls, external wall thicknesses, backward hooks and hollow bodies. The result of this innovative new development is now being used to the benefit of all of our customers.
