Motocyclettes -- Tableaux de bordIndex. décimale : 668.4 Plastiques, vinyles Résumé : In Modena, the homeland of supercars and th eMotor Valley of Italy, the first high-performance fully-electric motorcycle, "Ego", was born at Energica Motor company S.p.A. Ego was rigorously developed using F1 technologies and high-performance composite materials. Energica was created and engineered through the CRP Group, whose decades-long activity in the field of high-precision CNC machining and professional 3D printing, along with composite materials for additive manufacturing, allowed the creation of innovative and avant-garde solutions that have made Energica a unique model throughout the world.

Procédés de fabrication hybridesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Hybrid production chains have been increasingly in the spotlight in recent years. This also applies to the ‧combination of conventional manufacturing and additive processes in tool construction. With the example of an injection molding tool, it is shown how mold inserts produced by additive manufacturing can greatly shorten cycle times, and thereby significantly reduce unit costs. The important thing is to find a suitable combination of processes from the variety available. Note de contenu : - The process chain is becoming more challenging
- The combination : hybrid molding
- Designing for AM
- Spacer as a practical example
- Optimizing the tool by a bionic design
- Comparison of process chains : complexity has no extra costs
- Figure : Tool insert for a spacer of a glass fiber reinforced PA66. The example shows that hybrid manufacturing is suitable and provides added value, even with co:mparatively simple parts
- Fig. 1 : Apart from conventional tool building, hybrid molding also includes additively manufactured mold inserts and HSC milling

Véhicules électriquesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Developing an electric vehicle (EV) with a range of 1000 kilometres is not as impossible as many might asume today. As batteries become more and morepowerful, lowering the vehicle weight will be the key challenge to overcome to reach that ultimate goal. But how can manufacturers make cars lighter while at the same time keeping them safe ? Thanks to innovations in composite materials, engineering plastics and additive manufacturing, cars can now be both light and reliable. As a result, Evs are a step closer to a great breakthrough. Note de contenu : - Why lighter is better
- Aerospace leads the way
- No need to compromise on safety
- 1000-kilometre EV : coming soon ?
- Fig. 1 : Today's most pupular family EVs have an average range of 200 to 300 kilometres on a full charge
- Fig. 2 : The weight of an electric vehicle and the size of its battery pack have the greatest impact on its range
