Conformal Cooling Mold for “Venturi Cup”

Precision ADM and Melet Plastics Inc.

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 customer requested 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. The use of the optimized mold together with a decrease in wall thickness resulted in a warpage reduction of 42%; an overall warpage reduction of 54% was achieved with all other alterations included.
