Precision ADM has completed a conformal cooling mold project that developed an improved “Venturi Cup” for Melet Plastics. The goal of the project was to show how a mold optimized using additive manufacturing (AM) methods can increase quality and productivity. Additive manufacturing methods can be used to create molds featuring a coolant channels that follow the contours of a mold, drastically improving heat distribution during cooling. This has the added benefit of eliminating the task of drilling cooling channels.
A warping defect was reported in the production of a “Venturi Cup” part manufactured by Melet Plastics Inc. for use in an AGCO-Amity JV air seeder. The goal was a reduction in the warping seen in the large rectangular section of the part. Proposed alterations included changes in material, wall thickness and coolant temperature, as well as an optimized mold for cooling produced by Precision ADM using additive manufacturing methods.
