Milacron Holdings Corp. has partnered with Linear AMS, a Moog Company, to offer metal 3D-printed conformal cooling products as part of its DME product brand of mold components, molding supplies and industrial supplies.
New TruCool products within the DME line are designed to enable mold cooling. DME's conformal cooling solutions use direct metal laser melting (DMLM) to produce complex cavities, cores and components with conformal cooling channels. The process achieves shapes, paths and channel geometries impossible to obtain with conventional tooling. The result allows for complex cooling channels with greater overall coverage, even distribution of cooling and the ability to provide individual insert temperature control.
According to David Baucus, DME product manager, “The conformal cooling solution places cooling channels at the optimal distance from the mold surface, consistently following the geometric shape of any mold insert for any customer part, allowing the mold to maintain a targeted, consistent temperature that allows for complete thermal control with cooling times reduced up to 100 percent. This technology also allows for conformal venting solutions for those hard to reach areas of trapped gases, when requested by the molder.”
Milacron says the conformal cooling and/or venting optimized mold cavities and cores are available with hardness ranging to 56 HRC and an additional 0.25" rough metal to enable finishing to specification. Benefits of the conformal cooling solutions include cycle time reduction, complete and isolated thermal control, significant quality improvements, less scrap, increased flexibility in waterline designs, and the ability to visualize flow capabilities and thermal properties.
Linear AMS has more than 12 years' experience building 3D-printed conformal cooling inserts. “We’ve taken the lessons from over a decade of building DMLM parts and established design rules and process controls that enable us to make excellent quality components that meet or exceed customer expectations,” says David Hodge, Linear AMS vice president. “We are excited to partner with DME, a leader in the molding industry, who shares our focus for serving customers with superior products. When a customer is molding millions of parts, seeing significant process gains is a real eye-opener.”
