Abstract
This project shows the improvement of a three-gram capacity jar for cosmetic use, manufactured by the company Ingeniería, Pailería Industrial y Mantenimiento S.A. de C.V. (IPIMSA). The jar for cosmetic use showed a leak between the jar and the lid, by means of the leak test, in a vacuum machine. To determine the root cause, an Ishikawa diagram is used, later, it was analyzed that the 110 T horizontal injection machine (Van Dorn) is in perfect condition, the problem was identified when disassembling the plastic injection mold, since the plate for the string of the jar was machined with the concentricity offset by one millimeter, causing the walls of the string of the jar to be uneven and thin, which is why the objective of this project is to improve the machining of the string generating plate of the jar. Jar for cosmetic use, to meet the leak test by the customer. For the machining, the Haas VF2 CNC machining center with a resolution of 0.001 mm, from the Universidad Tecnológica del Valle de Toluca, was used.
