Hybrid tool construction

Generally it is possible to build the entire core by SLM, however to get the best performance at the lowest cost we can be easily made it by a hybrid construction technique so we can perform the additive Selective LAser Melting process on a base made by a conventional method such as milling or turning.

 

Cooling is always problematic at the top of the mould insert where cooling channels must be closed without any seam or Ampco/steell cap. The base of a core in traditional tempered steel like 1.2343 should be turned or milled and surface grinded, after that we add material with our technology to its top surface to build the critical zone.

 
The material built with Selective Laser Melting are then hardened to about 52-54 HRC and finished to remove the 0,3mm over mass left to provide enough material for finishing.
