MétauxIndex. décimale : 668.4 Plastiques, vinyles Résumé : hyJoin, the Kist + Escherich joining technology is mainly used where space is too limited even for a seal, and where bolting or gluing is not desirable. The partner materials are joined together in a few seconds for a media-tight, long-lasting, stable and highly resilient connection. Note de contenu : - The challenge of hybrid joints
- Customized heating tools thanks to fe simulation
- Structural guidelines for optimum joint design
- Particle-free joining for clean environment
- Many different uses thanks to flexible joining equipmentEn ligne : https://drive.google.com/file/d/175K0tuNggOJ6B4yCTw_A0r_PA7h1ZfPe/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=40558

PolypropylèneIndex. décimale : 668.4 Plastiques, vinyles Résumé : Functional integration instead of downstream assembly: moldmaker Foboha presented a sophisticated patented mold technology at K 2022 that could transform the market for disposable beverage containers in the next few years. The company is remaining tight-lipped about its current pilot project. This article describes the underlying Citi technology, which features a cube mold with integrated turning inserts. The new process saves production space, energy and cycle time. Note de contenu : - Simultaneous processes on four sides of the cube
- Compact hot runner in the tightest of spaces
- High-speed cameras for inline quality assurance
- initiative project for packaging applications
- Fig. 1 : The sprockets of the circular Citi tool elements interlock with each other and provide the vertical rotation. The entire cube then rotates horizontally
- Fig. 2 : 3-component part: first, the green frame is made of PP. This is followed by the blue TPE seal. Finally, the black lever made of POM is injection molded. It is attached to the frame by means of the pin and bush principle but remains movable

VerreIndex. décimale : 668.4 Plastiques, vinyles Résumé : Transparent functional and design elements often consist of glass and plastic materials. But there may be problems in bonding them using adhesives or adhesion promoters, since adhesives only have limited aging resistance and glass is usually not easily wetted. High-strength hybrid connections are made possible with a two-step process, in which a laser first creates micro- and nanoscale structures in the glass, into which the plastic melt can subsequently penetrate. Note de contenu : - Laser-structuring of glass materials
- Joining with new laser wavelength
- Factors influencing the bond strength
- Laser structuring of a glass sample by means of CO2 laser radiation : the microstructures are introduced into a glass substrate with a thickness of 3 mm at spacings of 1 mm. This is performed by means of a scanner system, which guides the laser beam over the glass substrate in multiple passes at high speed. When the laser beam impinges on it, the material is vaporized ; the ablated particles can be seen as a yellow jet of flame
- Fig. 1 : Glass- plastic hybrid bonds combine the specific advantages of the two material classes. A typical application is a car headlamp, which requires high transparency and shape flexibility
- Fig. 2 : Laser-based manufacture of a glass-plastic bond in two steps : Laser structuring and laser joining
- Fig. 3 : Glass-plastic hybrid bond after joining : the structured glass sample forms a firm bond with the planar sample of polycarbonate. The plastic was irradiated in the region of the microstructures on an area of 10 mm x 20 mm. Due to the high transparency of a the two joint parts, the molten region can hardly be seen with the naked eye
- Fig. 4 : Micrograph of the microstructures : the glass is ablated layer by means of a USP laser beam. Compared to machining by CO laser beam, the high-precision ablation can generate structures with hardly any damage.En ligne : https://drive.google.com/file/d/1tLXMfrHXT0yX1xES0SYw_ZfaaVd9tKHi/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=34717

Composites
MétauxIndex. décimale : 668.4 Plastiques, vinyles Résumé : As part of our automotive report, we wanted to know a little more about the perception and use of composite materials in the automotive sector in Germany, a country that is very advanced in terms of composites, with a well-established automotive know-how. Therefore, we approached Dr. Michael Effing, Chairman of the board of composites Germany, who answered our questions. Note de contenu : - Fig. 1 : Electric mobilitygoes hand-in-hand with lightweight technology, but this won't be enough to cope with all upcoming challenges. Increased functionalities like integrated sensors, antennas or air-condition within the composites parts become USPs (unique selling positions)
- Fig. 2 : Multi-material systems are the key to successful designs. The combination of metals and composites with advanced joining methods via laser techniques are becoming state of the art.

Polyméthacrylate de méthyleLe poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec.
