HAVER Extruder Screens


HAVER & BOECKER design and fabricate woven wire cloth extruder screens for melt filtration.

  • High quality and filtration capacity
  • Precise fitting filter elements
  • Optimum cost-performance ratio
  • Constant quality control during production

We produce extruder screens:

  • round, oval, rectangular or other special design
  • with one or several layers
  • with or without borders
  • with compressed edges

Extrudersiebe mit Extruder Screens with compressed edges are screen packs made of several layers of woven wire cloth. These layers are bonded together at the edges where they are virtually free from pores.

It prevents with great efficiency any horizontal melt leakage from the filter screen.

The fabrication of our own woven metal cloth and twilled weaves enables us to design the optimum sieve configuration for any given filtration requirement. A close cooperation with the engineers and users of such systems is of great importance to us.


Extruder screens for melt filters, type SF

Besides deadflat extruder screens and screening belts for endless filtration we specialise in fabricating filter candles, filter elements, screen tubes, cones and other three dimensional shapes. For each filtration problem we can offer a corresponding solution: Micron retentions from 6 to 500 micrometers (µm) are standard. There are special requirements with micron retentions down to 2 µm. Our specialists develop optimum filter configurations.

Extruder screens made from stainless steel woven wire cloth have demonstrated superior performance in melt filtration, as this material excells in durability and chemical resistance. Extruder screens made from other materials can also be delivered.
