INTRODUCTION:
Founded in 1895 and with nearly 130 years of company history, Wefapress is a reliable partner to the pulp and paper industry when
it comes to highly wear resistant spare parts from engineering plastics.
In times of high in昀氀ation and energy costs it is most
important to optimize the paper and board machine performance in
order to get the most value out of it. Wefapress Beck + Co. GmbH
supports paper mills all around the world with customized spare part
solutions which
- improve the paper quality
- increase machine uptime
- reduce the energy consumption
- reduce maintenance effort
- create cost savings and quick ROI

Whether the need is for high chemical, temperature or
wear resistant materials, the wide range of modi昀椀ed UHMW-PE
material grades from Wefapress has the right solution for each
application. Pulp mills bene昀椀t from the St9000MOS2 material as the
included lubrication additive reduces friction and wear while it also
resist perfect to agressive bleaching chemicals and high process
temperatures. Like this, the mills pro昀椀t next to reduced drive power
also from long life time and less maintenance effort.
When paper mills speed up the machines Wefapress has
the solution to close the gap between standard PE material and
dewatering elements in costly ceramic material. CeramX is a hybrid
material which combines the advantages of highly wear resistant
ceramic with the advantages of UHMW-PE like:

low cost
昀氀exible material which is easy to handle
lowest coef昀椀cient of friction
up to 3 times longer life time compared with standard PE
highest felxibility in pro昀椀le shape and type of perforation
possible local regrinding
short delivery times
no risk of cracks or sharp edges which might damage the
