Beispiele KlebstoffauftragAdhésifs liquides : Les exigences envers la technologie de collage

Le collage permet d’assembler de manière fiable. Cela a maintenant été démontré dans presque toutes les industries et dans une grande variété d’applications. Mais les exigences relatives au type de collage ne cessent d’augmenter. Il faut que ces dernières soient à l’avenir satisfaites.
L’assemblage de matériaux est la clé du succès. Et c’est là que le collage révèle son potentiel : car c’est la seule manière d’assembler durablement différents matériaux tout en conservant pleinement leurs propriétés. Toutefois, les avantages de cette technologie ne peuvent être exploités que si cette dernière est correctement planifiée et utilisée. >>plus

The resin impregnation process protects against environmental influences and can increase the service lifeL’imprégnation au goutte à goutte pour les moteurs électriques

L’imprégnation du rotor et du stator est une étape importante dans la fabrication de moteurs électriques. Avec l’électrification du groupe motopropulseur, en particulier dans le secteur automobile, la demande de moteurs résistants combinant une performance extrême et un faible niveau d’émissions sonores augmente. Ce livre blanc traite des solutions d’automatisation, notamment pour l’imprégnation des moteurs électriques, et des avantages des différentes méthodes d’imprégnation. Avec une technologie de dosage appropriée, l’imprégnation au goutte à goutte en particulier offre un grand potentiel pour optimiser les différentes étapes de production. >>plus

Beispiel ViscoTec AbfüllstationLe scellement au fil du temps

La dosage et l’application de joints d’étanchéité dans la construction aéronautique conventionnelle est un processus complexe qui peut être considérablement amélioré dans de nombreux cas. Dans la construction aéronautique du début du XXe siècle, les joints des réservoirs ou les conduits de carburant des avions par exemple, étaient généralement en feuilles de caoutchouc découpées. L’introduction et le développement des polysulfures aliphatiques par Thiokol Chemical Corp. en 1928 ont jeté les bases d’une optimisation ultérieure. Ce produit a été utilisé pour la première fois par l’US Air Force en 1941 dans un réservoir de carburant d’avion. >>plus

Additiv gefertigtes Epoxidharz-BauteilAdditive manufacturing with liquid materials

Evaluation of different additive manufacturing processes with liquids and pastes: The use of additive manufacturing processes is increasing within industrial applications, as they bring some significant customer benefits compared to conventional processes. Additive manufacturing is based upon the layered structure of a component. The production time therefore depends on the volume to be applied to the component. The geometric shape of the individual layers has a minor influence. This results in a greater amount of design freedom. >>more

Perfect dispensing of two-component silicones

Silicone has become one of the most versatile connecting materials and can be used across a huge range of applications. Although many users are only familiar with standard commercial « silicone sealants » in plumbing, the material has considerably more potential uses. Meanwhile, the ongoing development of silicones is opening new applications in the industry for future production methods. The development of new products and production methods means that users are constantly faced with new requirements in terms of silicone’s material properties. >>more

Automatisierte Abfüllung von Smoothies mit dem ViscoTec Hygienic DispenserPersonalized Food as part of our lifestyle

« Digitization » and « networking » are everywhere. New technologies play an important role in this and are also revolutionizing nutrition and fitness. Food production is also affected by our health-conscious way of life, as part of the personal lifestyle, because eating habits are closely related to the fitness hype. The biggest challenge that the industry needs to address is the conversion and adaptation of food production and related processes. In the future, manufacturers will need to be able to produce batch size 1 food whilst still being competitive. >>more

FDD 3D Drucktechnologie für hochviskose Fluide und PastenAdditive manufacturing processes are changing the industry

A comparison of 3D printing processes: 3D printed or additive manufacturing components are revolutionizing industrial production – and have been doing so for a long time. Various processes are establishing themselves on the market and breaking up the structures of conventional production processes. To produce an object there are now numerous, different possibilities available. The various additive manufacturing processes differ significantly in terms of the manufacturing processes of the classic ways of producing objects or parts. >>more

Dosierdruck Prozessüberwachung mit flowscreen und flowplus von ViscoTecIntegrated process monitoring of dosing pressures

The relative pressure sensor flowplus16 is specially designed for the requirements of semi and fully automated dosing processes. With the help of the Luer system, it can be integrated into a wide variety of applications in a space-saving manner. flowplus16 provides a temperature-compensated, linear output signal in the range of 0.1 – 10 volts and is ideally suited for implementation in industrial processes with higher-level control (PLC). Due to its properties, the dead space free fluid channel is particularly suitable for chemically aggressive materials. >>more

flowplus pressure sensor with sizesThe flowplus pressure sensor – physical principles and function

Sensors (from the Latin « Sensire ») are devices by means of which it is possible to detect physical or chemical properties of materials. As human beings, we are not able to perceive these properties accurately (e.g. pressure), without technical assistance, and therefore only estimate them. For this reason, measuring devices in the form of sensors, transform these properties into readable quantities which can be processed further. Pressure sensors are measuring devices for recording pressure as a physical quantity. Such sensors can be found in various aspects of life. >>more

tablet pill production. Blistering conveyerSolving complex pharmaceuticals dosing tasks

Dosing and filling applications with progressive cavity pumps: In the field of dosing and filling in the pharmaceutical industry, one usually thinks of water-like, non-viscous products such as solutions used for injecting. For the most part, these can be filled with a high degree of process reliability using hose pumps, rotary piston pumps and time pressure systems. However, special niche products such as suspensions or gels and ointments place different demands on the filling technology. Which are therefore better served e.g. by the ViscoTec Pharma Dispenser based on the progressive cavity principle. >>more

Aufbau eines Endloskolben-PrinzipsComparison of different metering pumps

What characteristics are required of a metering pump that is to process highly viscous and abrasive media that are sensitive to shear with a high degree of process security and, at the same time, tolerate changes in the flow properties of these media? The solution: a metering pump in accordance with the positive displacement principle. A progressive cavity pump (PCP for short) is a well-known example of a pump of this type. A PCP combines the properties of pumping the medium with low levels of both wear and friction, resulting in a long service life and increased energy efficiency. >>more

Farbbatches in der Verarbeitung.Plastics: Fillers, anti-friction properties & wear

Caused by the high requirements on components subjected to electrical, mechanical or thermal stress in various industries, the combination of diverse properties in the same plastic material is vital. Achieved by the addition of multifunctional fillers, the corresponding procedure is identified as additive applications. The high share of fillers and the corresponding abrasiveness of these additives place huge demands on the processing dosing technology. Against this backdrop the subsequent white paper depicts the need for additives as well as the process impact on the dosing of highly filled polymers. >>more

semisolid-pharma-abfuellen-webFilling pharmaceuticals that are viscous or contain solids

Conventional filling technologies such as piston or peristaltic pumps reach their limits when filling small quantities of viscous, medical or pharmaceutical products – such as gels, ointments, hyaluronic acid and polymers – with precision. Solids and abrasive products are used to be effect in these types of pump. It is exactly for these types of application that filling pumps using the endless piston principle are particularly suited. >>more
