Leak Detection

Tantec is a leading manufacturer of standard and customized Plasma and Corona systems for the surface treatment of plastics and metals to enhance adhesion properties. Our innovative organization offers a high level of know-how, continuously developing new Plasma and Corona equipment to help solve adhesion problems and to meet high customer demands.


Leak detection is very useful, when it comes to detecting a crack or pin hole in a plastic material, which would otherwise pass unnoticed. LeakTEC is a powerful electronic tool for non-destructive leak detection of non-conductive single layer materials.
The LeakTEC measures a leak between a high-voltage electrode (DC) and counter electrode which can either be grounded or running opposed polarity. The LeakTEC ensures full process control and traceability.

It is typical in field applications to surface test moulded and welded joints in medical devices like medical tubes, containers, pipettes, cannulas and extruded film for medical bags etc. This fully automatic test is capable of detecting pin holes even smaller than 3 microns by introducing an electrical potential between a detecting electrode and an electrical ground, (i.e. metal jig or mandrel holding the part) while the plastic part itself acts as the insulator.

In the event of detecting a crack or pin hole in the plastic material, an electrical contact is established between electrode and ground.

This pass/fail contact is processed via the integral generator module interfaced with the main machine control. The machine control can either enable a downstream ‘part-reject’ function or track trends in the manufacturing process, which can be fed back for early process adjustment or maintenance. Counter electrodes measurement is to ensure that all electrodes are fully working. Each counter electrode will then give out individual signal to be processed by the machine PLC unit.


To limit the high-voltage and minimize generation of static electricity Tantec offers its dual polarity system (patented).


Surface treatment with Plasma treatment technology offers innovative solutions to adhesion and wetting problems in many industries. Component preparation is an important step prior to bonding, painting, varnishing and coating processes. Plasma treatment provides an economical solution for the cleaning and activation of component surfaces before further processing. Plasma surface treatment improves wettability and adhesion of ink, glues and coatings on many different surfaces.
Our Plasma Treatment equipment and products are cost-effective.

Plasma treatment provides surface treatment and an economical solution for the cleaning and activation of complex surfaces before further processing. This is especially true for profiles with complex surfaces, that cannot be treated using regular corona treatment mechanisms. Our plasma surface treatment equipment is used for long-term adhesive bonding of plastics and metals, and we have many customizable solutions suiting your company and your products.

Plasma treatment is used in almost all industrial manufacturing processes, and we have more than 40 years of experience in delivering the right equipment for surface treating any material.


Corona treatment is a surface modification technique that uses a corona discharge to impart changes in the properties of a surface. Treating the surface, a material/an object with Corona Treatment will ensure bonding with printing inks, coatings and adhesives.

The purpose of corona treatment is to optimise the adhesion properties on polymer-based materials. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings which by nature present significantly high surface energies. Corona treatment is a widely used surface treatment method in the plastic film, extrusion, automotive and medical industries.

To obtain optimum adhesion, it is crucial that the surface energy of the substrate is equal or higher than the surface energy of the material to be applied to the polymer.
