Kunstofftechnik Filter und Siebe

Filtration technology

Filtration technologies are needed everywhere – in industrial plants, in medical technology and in automobile engineering. Maximum demands are made here in microscopically small areas. Material purity and absolute hygiene guarantee permeability at the highest precision.

Gore-Anlage in der Filtrationstechnik

Fields of application

Our filters are in used worldwide in vehicle, medical, industrial and household technology, as well as in cleaning and heating plants worldwide. Our products filter and separate even the minutest particles from contaminated substances such as blood, water, oil or air.

Filter- und Siebproduktion


Our production can be manual, semi-automatic or fully automatic. In the fabric preparation, any desired filter contours can be produced thanks not only to our freely programmable laser technology. If necessary, production can take place under white room conditions.



For our filters and screens, we use extremely sturdy and corrosion-resistant materials such as stainless steels or Monel. The minimum mesh size of our metal screens is approx. 5 µm and approx. 1 µm. (1 µm = 0.001 mm) for our plastics screens.

The OK process

Otto Klumpp Prozess

Our precision and perfection accompany the product on its complete journey from development through to delivery. All the work steps are recorded, analysed and evaluated down to the smallest detail by an innovative hardware/software network: This is comprehensive quality management at the highest level. And guarantees our customers the cutting-edge technology they can expect from Otto Klumpp.


  • Injection moulding prototypes
  • Moulds
  • Part optimisation
  • Automation systems
  • Complete production lines
  • Special machines

We develop injection moulding prototypes, moulds, automation systems, complete production lines and special machines for our national and international customers. We are pleased to support you in the design, optimisation and production of your parts and plastic products.


  • Mold-Flow
  • Rapid-Prototyping
  • Proto-tooling
  • Short lead times
  • Cost-saving engineering

Our qualified staff members carry out complex calculations for you and design your plastic mouldings. We use techniques such as Mold-Flow, rapid prototyping and proto-tooling. For you this means: Short lead times, cost-saving production and compliance with the demanded injection moulding part quality.

Mould Manufacturing

  • Moulds 60 x 60 – 1000 x 1200 mm and 7 t
  • 5-axis simultaneous milling, HDC and HSC millers
  • CAD/CAM networking at all workstations
  • Utilisation of synergy effects between
    large and small moulds

Only when the moulds are of the highest quality can series production costs and downline costs be minimised. With our modern, highly efficient plant, we can produce top quality high-tech moulds.


  • More than 40 machines with mould clamping forces from 25 to 1600 t
  • Injection moulds 60 x 60 – 1800 x 2500 mm and 40 t
  • Part weights from 0.004 g – 9000 g
  • Interchangeable cylinder sets on all the machine groups with flexible use of the injection units
  • 2K and multi-K injection moulding
  • Central material supply

Otto Klumpp has a broad spectrum of different machines for the micro and macro ranges. A high degree of automation and complete recording and monitoring of all parameters ensure end-to-end quality management.
