At the K 2025 trade fair, 8–15 October 2025 in Düsseldorf - Germany, CETA Testsysteme will present field-tested leak and flow testing devices that enable 100% quality control of plastic components in series production. Visitors will find CETA in Hall 6, Booth D76.
Quality control in the production processs
Industrial plastics production demands high standards of tightness, functionality, and product safety - whether for single-use medical devices, connectors, cooling systems, or packaging. Defective components can result in downtime, complaints, or safety-critical consequences. That is why the integration of routine testing as a 100% end-of-line testing into the production process has long been standard practice for many manufacturers.
Typical applications
Examples of plastic products that are successfully tested with CETA test devices:
• Injection-molded housings and hollow bodies such as bottles, canisters, plastic drums, IBCs with a volume of up to 1,000 liters - tightness against leakage of media
• Closures and caps - tightness
• Disposable medical products, tubes, and catheters - tightness and flow
• Connecting elements and plug connectors - tightness
• Cooling channels and fluid channels in plastic components - flow and tightness against leakage
• Membranes, filter inserts, and porous components (flow)
The variety of products ranges from small-volume precision parts to large-volume hollow bodies and requires the use of different measuring methods and device variants.
Comprehensive portfolio of testing devices
A comprehensive range of testing devices allows the right solution to be found for almost any testing task. Compressed air is widely used as a testing medium. Depending on the application, CETA leak testers with gauge pressure sensors or differential pressure sensors are used. The tightness of large-volume test parts with small leakage rates can be tested with leak testers equipped with a calorimetric mass flow sensor. The CETATEST 725 LV leak tester was developed specifically for leak testing large-volume products such as plastic drums and IBCs. The range of product volumes to be tested extends from 0.1 ml to 1,000 l.
Products whose flow is tested include membranes, filters, and pipes. With CETA flow testers, a range from 3 ml/min to 200 l/min can be covered using different laminar flow elements. The test devices are available with standard industrial interfaces. These enable the transfer of measurement results as well as the control and parameterisation of the test devices.
CETA test devices and calibration standards are delivered as standard and at no extra charge with an internationally recognised calibration certificate in accordance with DIN EN ISO / IEC 17025. Test devices are guaranteed for 3 years (optionally extendable to 5 years).
As a solution partner, CETA Testsysteme GmbH supports customers in all phases of the practical implementation of their testing projects: from product development, ensuring technical feasibility, and selecting the appropriate testing technology to series production and subsequent process optimisations.
