Contrôle -- Appareils et matériels
Industrie 4.0Le concept d’Industrie 4.0 correspond à une nouvelle façon d’organiser les moyens de production : l’objectif est la mise en place d’usines dites "intelligentes" ("smart factories") capables d’une plus grande adaptabilité dans la production et d’une allocation plus efficace des ressources, ouvrant ainsi la voie à une nouvelle révolution industrielle. Ses bases technologiques sont l'Internet des objets et les systèmes cyber-physiques.

Presses à injecterIndex. décimale : 668.4 Plastiques, vinyles Résumé : The plastics industry has been hard hit by the shortage of skilled staff, as fewer and fewer young people are choosing to enter the profession in this industry. Measures are available to increase the attractiveness of the plastics industry as an employer, but until they have an appreciable effect, the efficient deployment of the available human resources is becoming a survival issue for many companies. Here, digitalization opens up opportunities for supporting the well-trained technical staff and reducing the pressure on them. Note de contenu : - Automatic adjustment, control and analysis
- Process check list supports the use of smart assistance systems
- 30 minutes instead of eight hours
- Machine with analytical capabilities
- Automatic interpretation of the data
- The data network is becoming ever tighterEn ligne : https://drive.google.com/file/d/1MGF7NqlQ-v952ERaphzhGqGTRDwdZ3wI/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=40331

Qualité -- Contrôle
ThermographieIndex. décimale : 668.4 Plastiques, vinyles Résumé : Voids impair the strength of injection-molded parts, but they cannot be detected by conventional quality inspection methods. Injection molding machine manufacturer Engel, together with the Josef Ressel Center at the Wels campus of the University of Applied Sciences Upper Austria, has shown how active thermography can also be deployed to provide inline quality control during injection molding. The size of voids can be specifically influenced and held in check during ongoing production. Note de contenu : - More safety, especially for thick-wall parts
- More than 1000 parts tested and evaluated
- Visualization software clarifies correlations
- Holding pressure as a manipulated variable
- First step towards commercializationEn ligne : https://drive.google.com/file/d/1yqsK693hTx14EK0a0_V9savGZtj9wJk6/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=39336

Elastomères -- Moulage par injectionIndex. décimale : 668.4 Plastiques, vinyles Résumé : With the increasing digitalization of injection molding, new process parameters are coming under the spotlight. Engel, together with the Polymer Competence Center Leoben and Montan University Leoben, Austria, is using machine-learning methods to explore the potential of mold breathing for quality assurance in rubber injection molding. This research project was supported by the partner company SKF Sealing Solutions Austria. Note de contenu : - Trainings set as a basis for Subsequent inline error Identification
- Determining dynamic material behavior
- Correlation between mold breathing and cavity pressure
- Process monitoring with principal component analysis
- Fig. 1 : Mold breathing: The mold is compressed by the build-up of the clamping force. During filling, the resulting part generates an opening force, which is counteracted by the compression. The opening force is proportional to the cavity pressure and to the projected surface area
- Fig. 2 : The maximum mold temperature at the cycle end follows immediately after the setpoint values of the heating elements
- Fig. 3 : The tan(δ) values of the elastomer parts are strongly influenced by the mold temperature. SPE statistics allow changes in the process conditions potentially leading to rejects to be recognized
- Fig. 4 : Mold breathing responds with a delay compared to the cavity pressure, but then simultaneously reaches a pronounced peak. Maxima of mold breathing and cavity pressure are strongly positively correlated
- Table 1 : In preliminary tests, settings ensuring a stable manufacturing process were found for all process parameters. These parameters were held constant in all experimentsEn ligne : https://drive.google.com/file/d/1ByzLVJcNLyWQOSy5k_ghRzAgk3wVs-C-/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=35637
