Injection moulding

The injection moulding technique sees liquid polymers injected into a closed mould under pressure and removed from the mould further to cooling/cross-linking. Relatively high tool costs and cycle times of just a few seconds make the technique particularly suitable for very large-scale production. The materials used are generally either unreinforced or short fibre-reinforced thermoplastics.

 Working in cooperation with the ILK, LZS has mastered the development of complex injection-moulded structures – from the design of components that are injection moulding-compatible right through to process development and prototype manufacturing using industrial-scale equipment.

The integrated manufacturing of aircraft engine structures developed at LZS sees fibre-reinforced polyamide injected into shells consisting of laser-welded stainless-steel panels. The injection pressure is harnessed and used to precisely shape the shells into their final form. The interior and exterior cover strips are also injection-moulded polyamide parts.

Highly integrated long fibre-reinforced, multi-part, injection-moulded component

Multi-material designs facilitate the integration of a variety of material functions into a single component. Continuously reinforced structural elements bear primary loads whilst also minimizing the weight of the component. Integrated metal connection pieces and short fibre-reinforced ribbed structures make it possible to integrate additional functions into the component.
