Filters and sieves in plastic injection moulding

elfo ag develops and manufactures customised filters and sieves via plastic injection moulding. Modern toolmaking and precise production create components tailored to each application.

Variety of plastics:
A wide variety of polymers are used in manufacturing – from standard materials such as PE, PP and ABS to high-performance plastics such as PPS and PEEK. This ensures that the right material with the required mechanical, thermal or chemical properties is selected for each application.

Integration of filter materials:
We process all common types of fabric with application-specific mesh sizes, thread or wire diameters. The focus is on plastic and stainless steel meshes, supplemented by galvanised filter foils, nonwovens and membrane materials. Depending on requirements, the fabric is precisely embedded into the plastic component.

Alternative with moulded filter structures:
In certain applications, a filter structure manufactured directly using injection moulding replaces the mesh material. The design of the web widths and openings depends on the part design, material and area of application. This allows very fine, stable and reproducible structures to be created.

With this combination of precision, validated processes and material diversity, elfo ag offers reliable filter and sieve solutions.
