3D Systems’ metal additive manufacturing process and Cimatron mold design software enable significantly reduced cooling cycles for mold inserts If the temperature changes during the injection molding cooling cycle are large, the risk of parts warping will be greatly increased. Testing of conventionally designed and manufactured injection molded automotive ducts resulted in temperature fluctuations of 132˚C throughout the test, leading B&J Specialty to recommend to its customers the use of conformal cooling injection molded inserts to achieve more even cooling. .
