Filter technology and special processes

With our experience we can support you in the development of innovative and ecological filter systems. Whether overmoulded, clamped, welded or moulded in thin-wall technology - we find the optimum solutions for the most diverse applications. Be it plastic filter housings for process filtration in petrochemical fresh water filters or the filter in your coffee machine, we will find the right solution. The filters are used in very different branches of industry and research. The plastic housings are made of polyamide (PA), polypropylene (PP) and styrene-acrylonitrile (SAN), among others. Depending on their design and construction, the filters can be exposed to an operating pressure of up to 8.5 bar and an operating temperature of up to 70 °C. 

Filter units made of polypropylene (PP), polyamide (PA) and polyester (PET) with filter finenesses of 1 µm to 150 µm can be used for operating temperatures of up to 120 °C, depending on the material used.


Special manufacturing processes at aXpel injection AG complement our portfolio. We can help you to fully exploit the technical possibilities while taking into account the economic aspects. We will find the most optimal process for the tailor-made implementation of your project. 

Injection moulding with inserts 

In hybrid technology, inserts (metal contacts, cables, screens, threaded bushes or other inserts) are inserted into the mould either manually or automatically. Inserts are also inserted for dimensional stabilisation, which is particularly recommended when the moulded parts are subject to heavy mechanical stress. In the electrical industry, contact elements are mainly overmoulded. To ensure the correct positioning of the inserts in the series process, the coordination between the mould and the insert must be very precise. In this process, metal or plastic parts are inserted into the mould as functional elements and overmoulded.

Multi-component injection moulding 2K /3K

Plastic articles are increasingly being developed and manufactured from several components with the aim of obtaining "ready-to-install" serial parts from one injection mould. The multi-component process is very efficient and the material properties of the materials used in this process can be exploited even better. In contrast to the normal injection moulding process, in this process different materials or colours are injected one after the other into the tool. The components are joined together in different ways. Success depends on factors such as the joining properties of the plastics, the geometric shape and the processing parameters during injection moulding. If the process engineering principles are observed, the possible applications are virtually inexhaustible.

In Mould Labeling 

In the in-mould labelling process, cut, printed plastic films, so-called labels, are precisely inserted into the injection mould by means of a handling device. Using a vacuum or static charge, the labels are fixed and then back-injected with plastic. Using heat and pressure, the films, which are precisely matched to the plastic, are welded to the plastic melt in the filling and holding pressure phase to form a finished product. More and more often this technique is combined with stack moulds to increase output.
