In this article, the optimization of a medical product is presented, for this product injection molding was used as it is a process capable of providing low manufacturing costs, low times of transformation of the raw material and products obtained with different forms complex. The main factors were the mold temperature, melting temperature, injection time and cooling time. In the optimization design of experiments was used, later the most pronounced descent method was implemented, it was possible to adjust by means of the composite central design and the optimal point of the function was estimated by canonical analysis. Using the CAE Moldex3D software, the injection was simulated. The optimization reduced the total warpage of the piece up to 0.2 mm, resulting in more significant factors of the melting temperature, injection time and cooling time.
