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.
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.
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.
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®).
PA6, PA66 ...
- temperature resistance -40°C to +100°C (short term +150°C)
- high moisture absorption (e.g. humidity)
- high mechanical strength, rigidity and hardness
- good heat ageing resistance
- good fatigue strength
- colour: natural or dyeable
- reinforcement with glass fibre possible
- resistance to oils, greases, lubricants and weak alkalis
PEEK (polyetheretherketone)
- continuous service temperature +260°C
- high mechanical strength and rigidity
- high dimensional stability
- very good electrical insulation properties
- long-term heat stability, high heat deflection temperature
- resistance to aggressive chemicals and high-energy radiation
- biological compatibility
- very good wear resistance
- good sliding properties
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.
