Requirements in the east of the European Union

Whatever requirements of the dosing technology or in general to automation actually does the eastern area of the European Union have? Here a marketing area with high potential is ever more at growing. Many companies emigrated some years ago due to the enticing low wage level with their productions, these companies must reorient themselves now, in order to compensate this due to rising wages ever smaller becoming, formerly large advantage. Often very large investments in buildings and know-how and the structure of the coworkers locally is naturally in the long term to remain received. Nevertheless many assigned techniques became outdated in the meantime or also by personnel employment became simply too expensive. Thus companies, which want to renew their techniques, are confrontated with the problem to procure techniques like dosing systems which can be used the next two years still as manual work place. Afterwards however these systems are to be inserted as precise techniques into a lining up automation (robot, axis systems etc.) without large expenditure. This presupposes apart from the readiness in the infrastructure to visit still weak countries, also an intensive customer advisory service. By the way these countries are not as bad as it is often in peoples mind - so far despite company car with german license plate I always came back home again with it…

“Mobile” emptying system

now you know, why our barrel emptying system is called “mobile”…

Dosing of soldering paste

Yesterday I participated in a service employment. The customer doses soldering paste as a application on a metal part, dosing quantity approx. 1.5 g, and had a ViscoTec plant in use, which ran for 7 years nearly problem-free. The entire plant consists of the components dosing control with dispenser and product supply, whereby the product supply is implemented as agitating mixing system with evacuation. The soldering paste is enriched with many air and/or gas vesicles, which is sucked off by the vacuum produced by a vacuum pump. Several weeks ago one had cleaned the hoses and the storage vessel, and since then our Dispenser had twice failed. In addition for some time the dosing result was not satisfactorily. The failure cause of the Dispensers was fast found: during the cleaning apparent larger chunks of the somewhere hardened soldering paste came into the system, and blocked a nozzle. The ViscoTec Dispenser then must develop a very high pressure, this leads medium-term to the destruction of the construction unit stator. During this maintenance the operator tells by the way that the vaccum pump does not function ‚probably’ any longer. He hasn`t thought over it however no further, and from his boss he was not asked over remarkablenesses. Would have been so simple: if air is in the paste, then the dosing accuracy cannot be correct, this always leads to a bad accuracy, and/or above all also to a dripping at the nozzle or for the interruption of the application. The cause was a defective safety switch and fast found. A small cause - large effect: often this saying applies to problems when dosing. A sealing for 20 cent, which is not leak-proof, often causes costs of several 1000 Euro. And we are afraid nothing as much, as air in the system or in the product. Its George Senftl

Bonding in the automotive engineering

The adhesive technology forms frequently the substantial basis for the advancement of mixed-architecture constructions in the lightweight construction. Against this background the Bayern Innovativ GmbH organizes in co-operation with the Fraunhofer-Institut für Fertigungstechnik und Angewandte Materialforschung (IFAM), Bremen, the 7. BAIKA cooperation platform „Bonding in the automotive engineering“ in Nuremberg.

Innovative product developments and practically solutions to the topics

- bonding in carcass and assembling
- innovations by bonding in commercial motor vehicle construction
- interior solutions with the bonding technology
- innovative 2-component-dosing technology
- inspection of adhesive and sealant application

are discussed in this industry study group.

ViscoTec reported last year on the forum with the topic „Process-sure dosing of very viscous adhesive and sealing materials“. Pictures

Data base dosing

Probably in each company, above all if it concerns dosing of different adhesives, sealing materials or colors, the question often arises: did we make that already times? And above all: how did we make that? And were there problems? I do not know, as much 1000 different adhesives or sealing materials there are, beginning with anaerobic adhesive, over RTV silicones to UV adhesives. I know however that many of them require an individual dosing technology. Now we have dosed some hundred different products with surely already, made many errors, but gained evenly also very much experience, where one must watch out. So that this knowledge is not only present in our coworkers´mind, we began now the structure of a data base. Here now the most diverse plant parameters to all different products are deposited, if possible with exact product number and MDS, and all test results or customer experiences in this connection are stored. Thus if you should look for someone, which has already experience with a special product, just ask us. The probability that we know your application, is high. It doesn`t cost anything to ask, and one does not have to reinvent the wheel again.
