WE ENSURE INNOVATIVE MINIATURISATION
Microfilters and thin-wall technology
Weißer + Grießhaber represents precise plastic injection moulding in the micro range. We manufacture thin-wall, fine-structured and long-flow components ranging from microfilters and internal components to complex housings and connectors. Our solutions combine maximum precision and functional reliability with stable high-volume production processes.
One example of our development expertise is a glass-fibre reinforced microfilter with a mesh size of 70 μm and a web width of 130 μm, produced directly using hot runner technology. We manufacture these microfilters reliably in volumes of up to 500 million units per year.
For this technological achievement, Weißer + Grießhaber received the ZF Supplier Award, recognising our precision and innovation in plastics engineering.
We continuously push the boundaries of what is possible in plastic injection moulding and develop tailor-made solutions for demanding product requirements across a wide range of industries.
