A large number of products must be tight against the penetration of moisture or liquids. To ensure this, they are tested for leak tightness during the manufacturing process in time with the production line. This is a routine test, i.e. every product is tested (100 % end-of-line leak test).
CETA Testsysteme GmbH is a manufacturer of physical test equipment ("Made in Germany"). CETA has more than 30 years of experience in industrial leak testing and flow measurement in the production line. With a comprehensive range of testing devices, the right solution can be found for practically every testing task.
The use of compressed air as a test medium is widespread. With this, different types of products can be tested for leaks by using different test methods (e.g. products that can be filled directly, encapsulated products such as radio keys or sensors). Sometimes the leak test is combined with pneumatic function tests (preload, opening and closing points of valves). The range of product volumes to be tested extends from 0.1 ml to 1,000 l.
Depending on the application, CETA leak testers with gauge pressure or differential pressure sensors are used. Available pressure ranges are between -1 and 30 bar up to 400 bar with the pressure rise method (e.g. testing of injection valves). The leak tightness of large-volume test parts can be tested using leak testers with calorimetric mass flow sensors. Very low leak rates down to 10-6 mbar*l/s can be detected with hydrogen leak testers. Products whose flow is tested are, for example membranes, filters and cooling channels. With CETA flow testers, a range from 3 ml/min to 400 l/min can be covered. The usual industrial interfaces are available for the test devices. These enable the transmission of the measurement results as well as the control and parameterisation of the test devices.
Customers from the automotive industry, medical technology, heating and air-conditioning industry, fittings and household appliance industry, packaging industry and e-mobility use the CETA test devices for quality assurance and production assurance.
Every testing task is associated with specific requirements. The project starts with a preliminary technical clarification. This serves to select the appropriate test device configuration. Sometimes practical tests with original test parts are also necessary to assure the technical feasibility. For each project, the technical feasibility is clarified, taking into account the test requirements. This gives the customer the certainty that the testing technology offered will reliably fulfil the expectations and requirements in production practice.
The CETA service offer for integration into the production process includes commissioning and training and is supported by special online seminar programs. Furthermore, engineering services, process optimisations and the elaboration of test specifications are offered.
In addition, a large number of technical papers are available on the various aspects of leak and flow testing and on applications.
CETA Testsysteme GmbH acts as a solution partner who supports the customer in all phases of the practical implementation of his testing project (starting with product development, ensuring technical feasibility, selection of suitable testing technology, series production and subsequent process optimisations).
CETA Testsysteme will present practical solutions at the following trade fairs in the 4th quarter of 2022: The possibilities for integrating leak testing and flow testing into the assembly process will be presented at the MOTEK trade fair (04. - 07.10.2022, Stuttgart). Solutions for leak testing of plastic products will be presented at the world's largest trade fair for the plastics and rubber industry, the K 2022 trade fair (19 - 26.10.2022, Düsseldorf). And at the world's largest medical trade fair, Medica (14.11. - 17.11.2022, Düsseldorf), the focus will be on leak and flow testing of medical products.
