Can Dean Group produce rapid prototypes?

Rapid prototyping is available as an option either in our UK facility or overseas-supplied. By choosing rapid prototypes for your project, you can benefit from a swift product turnaround, product validation prior to full-scale roll-out and direct comparison testing of alternative design concepts, just to mention a few of the advantages this process offers.

What are Dean Group’s lead times?

Lead times vary depending on the complexity of the project but are, typically:

  • 6 to 8 weeks for tool development and samples
  • 6 to 14 weeks for production

This will depend on whether the project is sourced in the UK or overseas. Prototypes can be produced quicker as tooling is not required.

What investment casting processes does Dean Group offer?

As an investment casting manufacturing company with over 40 years of experience, Dean Group specialises in a range of processes designed to meet the requirements of your project and the demands of the industry. We offer aluminium investment casting (ELITE process) as well as premium grade investment casting and commercial grade investment casting processes, each with its own benefits.

What is the aluminium investment casting (ELITE process)?

Our aluminium investment casting (ELITE process) is similar to the well-known SOPHIA® casting process and produces high-integrity pressure-tight aluminium castings for the aerospace, military, defence, electronics and automotive industries. This process offers many advantages, from thin wall section parts and consistent high range tensile results to good surface finishes and flexible production volumes.
