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, with flexible geometries and additional functions integrated directly into the design.

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: 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.
Customer benefits for medical technology applications
Our customers benefit from a continuous co-engineering process – from the concept phase to series production:
- Optimised part design: Geometries are tailored to the injection moulding process and ensure reliable and economical production.
- Appropriate material selection: Plastic and mesh materials are specifically designed for the respective application..
- Precision: Highest manufacturing precision guarantees reproducible filter geometries.
- High process stability: Early feasibility assessments ensure efficient series production.
- Advance quality planning: Using methods such as process flow diagrams (PF), process failure mode and effects analysis (P-FMEA) and production control plans, we ensure that regulatory requirements and customer specifications are reliably met..
- Validation of processes: For medical technology applications, we support validation activities in accordance with current standards. These include IQ (Installation Qualification), OQ (Operational Qualification) and PQ (Performance Qualification). This ensures that the injection moulding process is demonstrably stable, reproducible and compliant with regulations.
With this combination of precision, validated processes and material diversity, elfo ag offers reliable filter and sieve solutions – even for sensitive applications with the highest quality requirements, such as those demanded in medical technology.
