We produce fibre composite parts endlessly in completely different combinations. Pultrusion produces profiles with a high degree of design freedom. The GFRP or CFRP fibres are soaked in a resin and usually coated with a thermoplastic. To save material, we also work here with foamed materials as the core. We produce simple geometries in a particularly cost-efficient pullwinding process. The profiles produced by pullwinding or pultrusion are often coated inline in our extrusion process or are used specifically as inserts to reinforce components produced by injection moulding.
In our technical centre, we develop different methods for processing fibres. For example, there is also a braided wheel and the option of incorporating foamed plastic elements. We advise, support you in the selection of materials and can carry out many tests in-house.
Together with our toolmaking and mechanical engineering departments, we develop tool and plant technologies suitable for series production, even for highly complex process combinations since fibre-reinforced profiles are often further integrated into subsequent manufacturing processes.
Customers also benefit from our global logistics. With a total of twelve production sites in Europe, Asia, Brazil and South Africa, as well as a network of wholesalers and service points, we are there for them worldwide.
In our technical centre, we test fibre-matrix combinations specifically for our customers’ fields of application. We focus on process engineering because, in addition to all the demands placed on the component, we always offer production-precise and cost-effective manufacturing. Our close cooperation between component design/construction and process engineering creates ideal conditions for the development of cost-efficient, energy- and material-saving material combinations and processes.
We deal with fibre insertion in almost all areas of the company. For all the geometrical freedom, we also offer injection moulding of short and long fibre pellets on different machine sizes.
Pultrusion offers a high degree of design freedom. We adapt individual component requirements to customer specifications by using different components and, if necessary, optimised geometries. Pultrusion offers scope for weight reduction, design of the geometry and at the same time high reproduction accuracy. Hybrid components are our focus in pultrusion. This includes not only the coating of pultruded reinforcing elements but also the injection moulding of functional elements, a connection with metallic components and, for example, the production of flexible profiles.
Winding technology can be used to produce very light solid profiles and pipes that feature low tolerances in the inner and outer diameters. A unique selling point of OKE is the use of a foam inlay as a lost mandrel, which can also be made of recycled material. It reduces the component weight and possesses mechanical values that are almost comparable with those of conventional solid profiles. Another special feature is the option of coating with a thermoplastic matrix, which we extrude inline.
Due to our technological diversity and our further developed and patented pullwinding technology, a combination of several, different technologies is possible. Our reproduction accuracy and production speed enable us to manufacture economical reinforcement elements for lightweight construction projects. We devise new approaches for your projects and support lightweight construction with our hybrid process!
Various thermosetting and thermoplastic materials offer a wide range of possibilities in combination with our process:
Fibre-reinforced profiles are often an interesting alternative to quite different materials, such as wood, concrete, steel and aluminium. With different fibres, matrices, cores and protective coats, we tailor our pultrusion profiles to your individual wishes and requirements.
In series production, there is practically no waste material. Only when cutting to length does a small amount of dust develop. Fibres, nonwovens, yarns and rovings are processed without any loss in the end product. The excess resin after impregnation is stripped off and further used via a recirculation system.
Our quality management accompanies production from goods receipt to delivery with consistently high precision. With our patented production process, we achieve low tolerances with high efficiency.
