Product Development

By services

What you can imagine is what we can create.

Our product development is driven by the experience and the expertise of multifarious industry projects. We offer complete system solutions with regard to product definition, product design, prototyping, product realization and optimization.

Our experienced and creative engineers plan, design and construct according to the needs of our customers. Once finished we put the design into reality in our workshop. Having everything it takes from steelwork to machining, milling, grinding, lathe-work and control engineering within our factory gives us a high grade of flexibility.

Continuously communicating with our customers and partners guarantee the ultimate in quality in regard to the development of functional specification as well as machine and construction documentation. Not only do we design entire machines and constructions from scratch but we also modify existing machines and production plants.


By cable, general

The first tubeless tubular strander – the Q-SVM.

Our all new prototype of a high-speed strander – a paradigm shift in cable production.

This new high-speed cable strander is lighter, safer and faster then conventional tubular stranding machines, incorporating many more interesting features.
