    This project deals with the manufacture of cladding by injection molding of PVC polymer as an alternative material for the construction industry, where the analysis and design of the cladding mold are carried out using CAD/CAM software programs. The use of CAD/CAM tools allows reducing both, production time and cost. As this process occurs through injection molding, custom products can be manufactured meeting the needs of various sectors. Through the determination to depend upon the technological process for the manufacture of cladding, tests are carried out to validate the mechanical properties of cladding through compression, impact, and flammability tests along with UV ray experiments, thickness, production, and commercial cost, which are parameters to determine the quality of the product. To simplify the manufacturing process, a technological report of this study was conducted through the description of adequate parameters for its correct production. The results were favorable as 896 cladding molds, with a thickness of 2 mm, a net weight of 25 grams, and a selling price of 3.73 U.S. dollars per square meter, were produced. Therefore, cladding commercial cost, as well as weight, are significantly lowered concerning what it would represent within the construction industry.

    Optimización mediante metodología de superficie de respuesta de los parámetros de fabricación de fachaletas mezclando concreto con triturado de tereftalato de polietileno reciclado y su incidencia en la resistencia mecánica

    People's wrong habits when recycling Polyethylene Terephthalate plastic bottles ends up in environmental pollution, a plastic bottle recycling machine was implemented in Santo Domingo of the Tsáchilas, and using a Nelmor brand plastic bottle crusher, G1215M1 model, Polyethylene Terephthalate is processed.Crushed recycled PET percentage variations of 15 -20 –25 percent are made in the mixture with dimensions between 6mm -8mm -14mm and aggregate of 3mm -8mm -11mm. This concrete composite material plus the addition of crushed recycled PET are added in a manufactured mold from Artisan 1 that is a silicone elastomer. 45 veneers are manufactured and 4-point flexural tests are made, after 21 days of being manufactured according to INEN 2554:2011 norm, variates between 0,50125 and 1,59958 Megapascal. To the 45 veneers after 21 days of being manufactured, compression tests are made according to the INEN 1573:2010 norm and variates between 1.80700 and 4.31367 Megapascal. An optimization is performed through a surface response methodology using a statistical software, determining the optimal parametersfor veneers manufacturing, where the maximum percentage in the PET mix is of 15 percent with a dimension of 14mm and aggregate size of 6,95 mm. It is recommended in future investigations to make concrete veneers plus the addition of crushed recycled PET with a maximum percentage of 15 percent as a in the mixture, 14 mm dimension and 7 mm aggregate size, and to add a pigment in the mix to give color to the veneers.
