Plastic Injection Plant

Polinter Plásticos, a Portuguese public limited company based in Carregosa, Oliveira de Azeméis, is dedicated to providing services for injection molding of plastic materials and, since February 2006, extrusion blow molding.

The company’s activity is focused essentially on the demanding and competitive market of components for two-wheeled vehicles ¬– bikes and motorbikes – as well as baby chairs for both vehicle types. The company went into business in 1980 under the name Oliveira e Silva, Lda, which was changed to Polinter Plásticos, Lda in 1988. In August 2009, its legal status was changed to Polinter Plásticos, S.A., a public limited company.

Polinter is currently 100% owned by Polisport SGPS, S.A.In 2005, as part of an internal restructuring process, the role of CEO was created. Since then, Polinter has actively pursued a strategy of investment and modernization which has resulted in remarkable growth.Polinter recently acquired two blowing machines, a 300 ton injection machine and several robots, in addition to modifying its layout in consultation with the Kaizen Institute. Furthermore, the company introduced a number of management tools such as the Balanced Scorecard, using a set of indicators regarded as fundamental to the implementation of company strategy.

Factors were systematically identified with a view to achieving the company’s objectives. In its ceaseless quest for quality and excellence, Polinter has implemented and certified a quality management system in accordance with NP ISO 9001: 2000. In July 2009, the company was distinguished by IAPMEI (Institute for the Support of Small and Medium Enterprises) as an SME Leader (an award granted for superior performance).

Virtually all of the products manufactured by Polinter are destined for the international market, insofar as they are acquired by the Group company Polisport Plásticos, which exports approximately 97% of them to over 60 countries in the EU and beyond.
