About Cast Iron CAD

Working with ideas

The physical product development process we use is flexible, & designed to be a framework to help physical product ideas navigate innovation & engineering.

The ideas that we are introduced to are sometimes simply a concept, and sometimes fully developed but need optimisation. We are very happy to work with any idea at any stage of its development, the process diagram helps frame all the activities that have already been considered and are ahead of us. 

Having a clear view of this journey is key to keeping everyone; client, designer, engineer & manufacturer on the same path moving forward
