    Selección y construcción de un sistema Vacuum Bagging (envasado al vacío) para el conformado de materiales compuestos en el Laboratorio de Materiales de la Carrera de Ingeniería Mecánica de la Universidad Técnica de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-09) Guerrero Villacres, Richard Bernardo; Bustos Tipantasig, Flavio Enrique; Paredes Salinas, Juan Gilberto
    This project was carried out due to the problem that exists to manufacture higher quality test tubes, with better properties and in less time in the laboratories of the Technical University of Ambato. Looking to improve the laboratories, the construction of the vacuum system was generated, which consists of a pump that absorbs the elements through hoses, with a resin trap in the process to collect the resin and avoid damage to the system, the mold to be used. It is a flat mold to generate test tubes that can be analyzed, on the test tube special layers are mounted such as: peelable fabric, perforated film that helps to spread the resin, absorption blanket that removes excess resin, these special layers are covered With a vacuum bag taped to the sides of the mold with sealing tape, two vacuum valves are inserted connecting the vacuum system between the resin container, the cylinder, and the resin trap. The project concludes with the performance of functional tests for the specimens made with the developed machine.

    Diseño y construcción de un magnetrón para pulverizácion catódica para el Laboratorio de Materiales de Ingeniería Mecánica de la Facultad de Ingeniería Civil y Mecánica de la Universidad Técnica de Ambato

    Due to a great research for the development of technology that allows us to study and analyze coatings on surfaces, their processes and techniques with which the properties of the surfaces of the materials are modified, this technical project is carried out which aims, the design and construction of a magnetron for a sputtering equipment, whose function is to provide coating to metal surfaces, using the technique of sputtering of direct current and magnetron (Magnetron sputtering DC). In the theoretical and analytical, the versatile design stands out, with a changeable blank, a large vacuum chamber, where the samples can be manipulated and a removable magnetron, built with accessible material with properties that support the corrosion to which it will ever be , The selection of permanent magnets of high power (Neodymium Magnets), a vacuum pump was made, the quality is important for the formation of plasma and the obtaining of coatings, in addition to having a liquid cooling system, which allows maintain a stable temperature, avoiding overheating and prolonging the time of use, a voltage variator and a transformer that allows to raise the x10 voltage with a rectifier bridge that converts alternating current (AC) into direct current (DC). This team allowed the obtaining of metallic coatings for the development of future research carried out by students and teachers in the materials laboratory of the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato.

    Diseño e implementación de un sistema de vacío centralizado en el proceso de elaboración de jamones en la empresa de carnes procesadas fabrica Juris Cía. Ltda.

    Currently the production of processed meat products is a competitive market, one of its referents is Juris Factory; its main products are those of the line of hams. Within its manufacture the process of massage is constituted in one of the most critical, because within this gives the rupture of the muscles product of this is presented a detachment of oxygen which must be extracted. By means of tests it was determined that the required vacuum pressure is 10 mbar; we proceeded to the design of the vacuum accumulator tank based on the vacuum demand for the containers to work between 70 and 80% of their nominal capacity taking as a result the sum of these empty spaces and a safety factor due to grid issues. pipelines reaching to establish the capacity of the tank in 1.1 cubic meters. Calculations were performed according to the recommendations of ASME Code Section VIII Division 1 in the literals applicable to vessels under vacuum pressure. The pipeline diameter was selected starting from the volumetric flow that mobilizes the pump and the recommended velocity for pressure pipes, and then the vacuum pressure losses were calculated due to the pipe length and instrumentation. Finally we proceeded to the assembly and assembly of the piping system and the control and force circuit; the operating tests were performed leaving the operating and operating system.
