Powell and Harber, in partnership with the University of Wolverhampton, has investigated the application and manufacture of Direct Metal Laser Sintered (DMLS) prototype and bridge tooling for low-volume manufacture.

The aim of the project was to investigate the lead-time reduction and mould cycle-time reduction

The company claims that the core and cavity was suitable for the DMLS process due to its complex features and part size, and two pairs of inserts were able to fit on the DMLS platform together in one build.

A quick-change mould tool designed by Powell and Harber was used to produce prototype parts in production-specified materials.

Conformal cooling channels unique to the DMLS process were incorporated in order to achieve better part quality and reduced cycle times for the moulding of the components, Powell and Harber claims.

Key specifications

  • Cycle time reduced by 30 per cent
  • Impression tooling manufactured in 70 hours
  • 50 per cent time saving over conventional toolmaking methods
  • 40 per cent cost saving for tooling manufactured
  • Lead time saving of four weeks
