Conformal Cooling using DMLS and Direct Metal Laser Sintering Technology to Reduce Cycle Time

Posted on January 22, 2010 at 10:29am 0 Comments

Conformal Cooling

Conformal cooling is defined as the ability to create cooling/heating configurations within a tool that essentially follows the contour of the tool surface or deviates from that contour as thin/thick sections of the part may dictate for optimal thermal management. The objective typically is to cool or heat the part uniformly. Conformal cooling provides a tremendous advantage in mold tooling through significant reductions in cycle times. Other than the obvious… Continue

Good day,

I picked interest on you after going through your short profile and demand it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on (kayimivedor@gmail.com) for the full details.

Have a nice day.
