Temps de cycle (production) -- RéductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : The new Reverse Cube developed by Foboha manufactures various components or multi-component parts from varying materials in one step and assembles individual parts into finished products independently from the cycle time using an integrated handling robot. The automated process improves quality, accelerates cycle times by up to 40 % compared to separate injection molding and assembly processes, and thus enables substantial productivity gains at lower costs. Note de contenu : - A new process for multi-component parts
- A valve hot runner system for narrow process windows
- Higher production volume and lower unit costs
- Bespoke injection molding and robot technology
- Automated monitoring and control of the manufacturing process
- Monitoring the condition of injection molds
- Figure : Two thermally separated cube molds rotate in opposite directions at a 90°C angle. Injection and cooling of component 1 (roller made of PP) and component 2 (female connection made of POM) staggered by 180°C
- Fig. 1 : A reverse cube allows both plastic parts - a roller and female connection - to be manufacturated and assembled in a single work operation
- Fig. 2 : The 6-axis robot removes the rollers from the lower cube half at the same time as the injection cycle (shown in a dry run here) and inserts them into the female connections in the top cube half cavities
- Fig. 3 : The injection-molded components are ready for removal after each semi-rotation of the two thermally separted cube molds
- Fig. 4 : The software and hardware for the allrounder Cube 2900 injection molding machine and the quality assurance evaluation system were adapted to match the new mold technologyEn ligne : https://drive.google.com/file/d/1zO7f9DueaBGbqCuuuNBtCg0myExfHHGh/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=33652

Titre : A simple cascade : Sequential injection with a 6-fold valve gate system for a floor grate Type de document : texte imprimé Auteurs : Franciska Thomas, Auteur Année de publication : 2021 Article en page(s) : p. 24-27 Langues : Anglais (eng) Catégories : Canaux chauffants
Matières plastiques -- Moulage par injection
Moules d'injection -- Conception et constructionIndex. décimale : 668.4 Plastiques, vinyles Résumé : Products intended for use in building services must meet very high quality requirements in terms of both their constituent materials and functionality. A single-cavity mold for a floor grate made by Barku, which appears to be a simple part at first glance, called for a certain level of technical sophistication. This was provided by a moldmaker with the necessary technical understanding and hot-runner manufacturer Witosa who, between them, devised the right solution for what proved nevertheless to be a complex mold. Note de contenu : - Six individual drives for cascade control
- Challenges for the mold maker and hot runner manufacturer
- Coated needles for process optimization

RhéologieIndex. décimale : 668.4 Plastiques, vinyles Résumé : Color exchanges are a troublesome problem in plastic processing, particularly if hot-runner molds are employed. The start-up scrap produced during color exchange and the machine downtime must be reduced to a minimum. The best solution is based on optimization of the production technology and does not require modifications to the machine, mold or material. Note de contenu : - Considerations on the flow behavior and particularly the wall slip
- Fundamental realtionship between wall-Slip behavior and color exchange behavior
- A highly beneficial phenomen
- Injection velocity corresponds to shear rate

For instance, by texturing the mold cavity’s surface, it is possible to give the panels the appearance of a stone wall. This approach is also being used increasingly in Russia.
