MOLDS AND METHODS OF MAKING MOLDS HAVING CONFORMING HEATING AND COOLING SYSTEMS

摘要

A method for forming a mold apparatus comprising: forming a cavity portion through an additive manufacturing process; wherein the cavity portion comprises a cavity molding surface having a surface roughness of greater than or equal to about 0.025 μm and a plurality of cavity fluid channels; wherein the cavity fluid channels comprise a profile conforming to the profile of the cavity molding surface; treating the cavity molding surface to reduce the surface roughness to less than about 0.025 μm; forming a core portion through additive manufacturing; wherein the core portion comprises a core molding surface and a plurality of core fluid channels; wherein the core fluid channels conform to the core molding surface.
