The conformal cooling flow channel can effectively reduce the uneven cooling of the parts, increase the cooling speed, and improve the life span of molds. Thanks to the technological maturity of metal 3D printing technology, mold designers nowadays can focus on the performance of molds and arrange cooling water channels without worrying about their excellent designs being unable to be manufactured. SLM systems help the industry break through the manufacturing bottleneck, and integrated high-performance molds will become the protagonist in the future.
