The use of inserts made with additive manufacturing offers an effective and uniform cooling method for injection moulds. These components improve the performance of the production process and play a key role in the final quality of the plastic parts

Optimised mould cooling using this technology results in:

  • Reduced cycle times.
  • Improved aesthetic finish of the product thanks to a more uniform temperature of the cavity surface.
  • Reduced residual stress, and consequently less warpage of the finished part.

Selecting the right additive manufacturing process

To optimise mould cooling, HRS Flow proposes the use of Selective Laser Melting Technology, or SLM. Unlike traditional machine tool processes involving the removal of metal, SLM produces metal parts by the gradual addition of successive layers of laser-melted powder. The process provides greater design flexibility and a lower overall cost to produce the part.
