Casting a cleaner future.

From battery enclosures to EDUs, we're using our casting expertise, material knowledge and prototyping approach help solve the complex EV problems of lightweighting, part count reduction and material optimisation.

Aluminium castings allow us to create the lightweight, complex metal shapes required to reduce fuel use and emissions in electric vehicles, while still meeting performance expectations.






Creating lightweight, complex metal shapes for EV. Quickly.

  • We use the flexibility of sand casting prototyping to create complex geometries in a single shape, at a relatively low cost and in a range of alloys.

  • Our materials knowledge and expertise, especially in aluminium castings, allows us create Make Like Production (MLP) properties and We also develop unique alloy chemistries for lightweighting, recyclability and durability.

Creating lightweight, complex metal shapes for EV. Quickly.

  • Our Magma simulation software allows us to prototype properties prior to production, reducing any unnecessary weight with overengineering.

  • Our 3D sand printing capabilities allows us to deliver EV component parts with super short lead times. 

  • We use CT scanning to ensure we meet specifications and tolerancing requirements, delivering high-integrity castings.
