Vélo -- MatériauxIndex. décimale : 668.4 Plastiques, vinyles Résumé : The particle foam crowd cannot complain about a lack of interest by potential users. At least as far as demand for products with high-quality functional and optical surfaces is concerned. However, development has stagnated since the joint research project SamPa sponsored by the German Federal Ministry of Education and Research reached its conclusion. There is an urgent need for action. Note de contenu : - Skin forming for better surface quality
- Electromagnetic waves instead of steam
- Advantages of variotherm mold temperature control
- Using plasma to render EPP surfaces "compilant"
- Process monitoring requires complex sensor technology
- Figure : Before flow coating with PU, the EPP surface must be activated
- Fig. 1 : In the Wave Foamer, electromagnetic waves cause the polymer chains to oscillate, so that the foam beads are heated from the inside outward
- Fig. 2 : A-pillar of particle foam with textured surface
- Fig. 3 : Schematic representation of the skin formation in five steps
- Fig. 4 : Section through an A-pillar produced by the IMPFC process
- Fig. 5 : To activate the EPP surface, the chemical and physical interaction between the plasma and plastic causes, a) reaction of an isocyanate functional group with the PU layer, and b) a fixed atomic bond between the PU layer and EPP
- Fig. 6 : After pretreatment with plasma, EPP can be flow-coated with a semi-rigid foam, with which this pattern is flow-coated with a further PU system
- Fig. 7 : EPP saddle as a technology demonstrator : functionalized with a printed circuit and flow-coated with clear coat to investigate the depth effect (le) ; flow coated with "piano black" PU (right) in different layer thicknesses (0.5 mm, 1.5 mm and 2.5 mm), in order to illustrate the color intensityEn ligne : https://www.kunststoffe.de/en/journal/archive/article/a-glossy-surface-quality-f [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=33983

Terpolymère acrylonitrile butadiène styrèneIndex. décimale : 668.4 Plastiques, vinyles Résumé : A stable system technology that can be extended with further process components as needed is the basis of a range of innovative applications in foam injection molding. These are solutions for improving the surface quality as far as high gloss, for the partial combination of non-foamed and foamed molding areas and for foaming thermoplastic elastomers. Note de contenu : - Stable system concept
- What possibilities are offered by high-pressure foam injection molding ?
- High-gloss surfaces thanks to dynamic mold temperature control
- Elastomers, too, are suitable for foaming
- Foamed and non-foamed sections in one part
- Mechanical characteristics can be accurately predicted
- Agreement between theory and practiceEn ligne : https://drive.google.com/file/d/1JjhtE5RquRK9XN1SG4MZyBy9OJq7T3ZQ/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=22634

Terpolymère acrylonitrile butadiène styrèneIndex. décimale : 668.4 Plastiques, vinyles Résumé : In standard applications, the new intelligent temperature control units from Single achieve energy savings of between 40 and 70 %. Such energy-saving operation also has a positive effect on cooling water consumption and – as a result – on the service life of the pump. The higher costs for this option are amortized in a short period of time. Note de contenu : - The adaptative control strategy
- Beneficial side effects
- The tests in detail
- Evaluation and analysis
- One to two year amortization period
- TABLES : 1. Tests with acrylonitrile-styrene (ABS) at approx. 30°C : The reduction of the volume flow results in considerably lower energy consumption at identical molded part quality (from approx. 1kW to approx. 300 W) - 2. Automatic control mode with acrylonitrile-butadiene-styrene (ABS) at approx 30°C. With a tolerance window for ΔT of 5K or 6K, the temperature control system adjusts the pump speed automatically and provides significant energy savings (from approx. 1kW to approx. 500 W) - 3. Tests with polycarbonate (PC) at approx 100°C : Here too the reduction of the volume flow provides substantial energy savings - at identical molded part qualityEn ligne : https://drive.google.com/file/d/1BhaJLQEbTh83YdFmqPOlQ85TDX5TqrHX/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28047
