Plastics engineering

Welcome to the Wire Weaving Division and the experts of plastic injection moulding. Are you wondering about this connection? We would be happy to explain how these two product areas are interwoven and where our strengths lie in plastics technology.

Metal wire cloth is at the heart of countless filtration, homogenisation and other applications with solid, liquid, and gaseous media that benefit from the precise uniform structure and stability of wire cloth.

Perfection in detail: This not only applies to the filter medium itself, which covers a vast spectrum from the finest structures in the micrometre range to coarse structures. It also applies to the filters and fabricated parts into which the wire mesh is further processed, among other things, with a plastic edging.

The combination of metal wire mesh and plastics engineering poses new challenges even for experienced employees in this field, but it also offers many convincing advantages. We would be pleased to present a selection of hybrid elements.

From police filters to heating elements, among other things, in mobility, hydrogen, and electronics

Plastic injection moulding

Definition and advantages

In plastic injection moulding, edgings and complete fabricated parts are produced by injecting plastic melts into the cavities (hollow spaces) of a mould and compressing them under pressure.

The advantages of this process are:


  • Realisation of complex and precise moulded parts with low weight.
  • Stabilisation of three-dimensional fabricated parts made of metal wire mesh.
  • Gluing the components into a sealing compound.
  • Realisation of chemical-resistant hybrid elements.
  • Simple processing of an assembly element.
  • Economical series production due to short cycle times.
  • Production line for plastic injection moulding

As a solution provider of filters and fabricated parts made of metal wire mesh, it is our concern to develop fabricated parts for individual applications and installation situations.

With the requirements of our customers for the functionality and handling of filter discs, deep-drawn parts, cylinders, and filter cartridges made of metal wire mesh, not only has the relevance of plastics technology increased over the last 20 years, but also the complexity of the product moulds and production facilities.

Today, Haver & Boecker employs specialists in plastics engineering to meet the highest demands in this field.

Plastics engineering in connection with wire mesh is a discipline of its own, which also takes us experts to a new level.

Fully automated production and 100% control

The development of individual production systems and moulds take place in the in-house tool making of the wire weaving division. From feeding our wire mesh pieces to filling the cavities with suitable plastic to the final inspection of all fabricated parts, we have complete control over the process and can make optimisations and adjustments directly.

Precision all along the line:

From wire mesh to plastics engineering

From PA66 to PEEK – all plastics at a glance

In addition to thermoplastic elastomers, polyamides, and polypropylene, the thermally resilient special plastic PEEK has proved particularly suitable for injection moulding components. It is not only heat-resistant but also flame-retardant. A new compound was developed from this high-performance thermoplastic for the series production of an electrical resistance heating element (HAVER AdPEEK®).

Speed and resource conservation always in view

More efficiency through the latest plant technology

Depending on the product specifications, we produce hybrid fabricated parts with horizontal and vertical injection moulding machines. Due to simpler handling and lower mould costs, we tend to use vertical machines more often under suitable conditions, as the wire mesh is placed flat in the cavities, and plastic over-moulding is possible without additional fixing.
