TWDI – Thin Walled Ductile Iron - An already green casting process which added the ability to redesign lighter parts for vehicles for better fuel efficiency and eV range.

Lightweighting of transportation vehicles reduces fuel consumption and carbon emissions. It also decreases battery weight and increases range on electric vehicles. Lightweighting in agriculture reduces soil compaction.

The solution is ductile iron which has the optimum combination of strength, density, and cost compared to alternative materials. The reason its use has been limited is that historically casting defects occured in thin sections under 6mm. Using the environmentally friendly lost foam casting process, innovations in foam blowing technology, and a metallurgical alloying process that prevents casting defects, Skuld's ductile iron can be cast as thin as 1mm. This is 66% thinner than the best world class commercialized casting processes. This process and material enable the redesign of castings, machined components, and weldments made from iron, steel, or aluminum to save weight and cost.

Key features
