Description
As the name implies aluminium cast tooling plate is manufactured using a casting process, giving the material a fine granular structure. Conventional aluminium plate is manufactured from forged wrought ingots rolled to size and heat treated. Cast aluminium tooling plate is manufactured close to finish thickness by a horizontal continuous aluminium flow casting process delivering a uniform fine grain structure. The cast plate is then heat treated above 370°C for close to 10 hours to fully anneal (stress relieve) to remove any manufacturing stresses. The cast plate is then lightly machined to its finished size and protective films applied.
