Recover. Reinforce. Reimagine. <\/h4>\n\n\n\n

At PENA, we believe that a worn screw or barrel is not the end of its lifecycle, but the beginning of a new, optimised stage.
Our refurbishment service combines technical analysis, advanced repair processes and engineering improvements to restore your components to original performance levels, or even exceed them.<\/p>\n\n \r\n\t\t\t\r\n\t\t<\/div>\r\n\t\n \r\n\t\t<\/div>\r\n\t<\/div><\/section>\n\n\n\r\n\t\t

          Technical Analysis for the Ideal Assembly Size<\/p>\n<\/blockquote>\n\n\n\n

          Every polymer, formulation and application requires different processing conditions.
          At Talleres Pena, we analyse: <\/p>\n\n\n\n

            \n
          • Required shot size or production capacity.<\/li>\n\n\n\n
          • Polymer type and thermal behaviour.<\/li>\n\n\n\n

          • Processing parameters.<\/li>\n\n\n\n
          • Target machine performance.<\/li>\n<\/ul>\n\n\n\n

            Based on this analysis, we define the optimum screw and barrel configuration, creating a plasticising unit perfectly matched to your production requirements.<\/p>\n\n \r\n\t\t\t\r\n\t\t<\/div>\r\n\t\n \r\n\t\t<\/div>\r\n\t\n\r\n\t\t\t \r\n\t\t<\/div>\r\n\t\n\r\n\t\t\t \r\n\t\t<\/div>\r\n\t<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"
