In this study, we investigated the suitability of in-mold pressure sensors to control the injection molding process in multi-cavity molds. We have conducted several experiments to show how to optimize the clamping force, switchover, or holding time by measuring only pressure in a multi-cavity mold. The results show that the pressure curves and the pressure integral are suitable for determining optimal clamping force. We also proved that in-channel sensors could be effectively used for a pressure-controlled SWOP. In the volume-controlled method, only the sensors in the cavity were capable of correctly detecting the end of the filling. We proposed a method to optimize the holding phase. In this method, we first determined the integration time of the area under the pressure curve and then performed a model fit using the relationship between the pressure integral and product mass. The saturation curve fitted to the pressure data can easily determine the gate freeze-off time from pressure measurements.<\/jats:p>","DOI":"10.3390\/s23031735","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T02:06:43Z","timestamp":1675649203000},"page":"1735","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Multiple In-Mold Sensors for Quality and Process Control in Injection Molding"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8902-6818","authenticated-orcid":false,"given":"Rich\u00e1rd Dominik","family":"P\u00e1rizs","sequence":"first","affiliation":[{"name":"Department of Polymer Engineering, Faculty of Mechanical Engineering, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3., H-1111 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4521-2771","authenticated-orcid":false,"given":"D\u00e1niel","family":"T\u00f6r\u00f6k","sequence":"additional","affiliation":[{"name":"Department of Polymer Engineering, Faculty of Mechanical Engineering, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3., H-1111 Budapest, Hungary"},{"name":"MTA-BME Lend\u00fclet Lightweight Polymer Composites Research Group, M\u0171egyetem rkp. 3., H-1111 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3732-7296","authenticated-orcid":false,"given":"Tatyana","family":"Ageyeva","sequence":"additional","affiliation":[{"name":"Department of Polymer Engineering, Faculty of Mechanical Engineering, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3., H-1111 Budapest, Hungary"},{"name":"MTA-BME Lend\u00fclet Lightweight Polymer Composites Research Group, M\u0171egyetem rkp. 3., H-1111 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7391-7085","authenticated-orcid":false,"given":"J\u00f3zsef G\u00e1bor","family":"Kov\u00e1cs","sequence":"additional","affiliation":[{"name":"Department of Polymer Engineering, Faculty of Mechanical Engineering, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3., H-1111 Budapest, Hungary"},{"name":"MTA-BME Lend\u00fclet Lightweight Polymer Composites Research Group, M\u0171egyetem rkp. 3., H-1111 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"889","DOI":"10.3144\/expresspolymlett.2019.77","article-title":"Combination of 3D printing and injection molding: Overmolding and overprinting","volume":"13","author":"Boros","year":"2019","journal-title":"Express Polym.
