The German LamiPreg process is a one-step, continuous and therefore cost-effective technology thermoplastic sheets and metal foils can be laminated on top of each other and fibreglass and carbon fibre fabrics with plastic impregnation. Thermoplastics can be components containing metal inserts embedded in thermoplastic materials by hybrid injection moulding Good adhesion between the inserts and the plastic is ensured by the use of adhesion can be improved by the use of adhesion promoters.
