Dimensional Stability and Process Capability of an Industrial Component Injected with Recycled Polypropylene 2019 Access copy available to the general public Unrestricted The usage of recycled polymers for industrial purposes arises as one of the most promising methods of reducing environmental impact and costs associated with scrapping parts. This paper presents a systematic study of the dimensional stability of a raw and 100% recycled polypropylene subjected to realistic environmental conditions occurring along its working life. The component studied is an internal part of an induction hob assembly. Industrial samples manufactured with both materials, in the same mold, and in the same injection machine, are subjected to ejection conditions, storage conditions (50 °C), and extreme performance conditions (80 °C). Induced dimensional changes are registered and analyzed using a coordinate measuring machine, and a tactile sensing probe. To verify the process capability of the samples manufacturing, Cp and Cpk values are calculated to evaluate the suitability of the recycled material as an alternative. Results conclude that, although the use of recycled material implies slight differences in terms of dimensional stability due to the changes induced in the polymer structure, these differences are not significant enough to affect the injection process capability. Therefore, recycling arises as one effective method to reduce both overruns associated with the consumption of raw polypropylene material and its environmental impact. info:eu-repo/grantAgreement/ES/DGA/T08-17R info:eu-repo/grantAgreement/ES/MINECO/RTC-2014-1847-6 info:eu-repo/grantAgreement/ES/MINECO/RTC-2017-5965-6 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.426 2019 POLYMER SCIENCE 16 / 89 = 0.18 2019 Q1 T1 0.704 2019 Polymers and Plastics 2019 Q1 Chemistry (miscellaneous) 2019 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-9137-3387 Elduque, D.
