Perfectly tailored to your needs

High-quality plastic containers made to measure

Containers | Tank | Storage tank | Boiler

Sena Plastics is able to supply its customers with all types of plastic tanks or plastic containers. All weldable plastics can be used. Depending on the size, pressure or medium, the choice falls on a pure thermoplastic or a composite material. For example: PP/GFK or PFA/GFK. The choice of configuration is unlimited and allows the product to be perfectly adapted to the customer's needs for existing or new systems.

Effective exhaust air purification systems

The construction of exhaust gas scrubbers has been an integral part of the Sena Plastics AG product range for many decades. Our exhaust air systems ensure clean air and comply with the latest regulations.

Special designs for individual requirements

As a buyer, you will not always find ready-made technical solutions to your problems on the market. These are difficult to find because plastic constructions are not very common and well known.

Sena Plastics works closely with its customers to offer customised solutions. We have the knowledge regarding the chemical resistance of plastic and the possibilities for implementing ideas for the finished product. This makes it possible to design unique constructions that precisely meet customer requirements, such as customised expansion joints, protective rings, baskets, injectors, nozzles, filters, covers, protective casings, etc.

The possibilities are numerous. Our components can be used to construct stirrers, columns, heat exchangers, high-voltage testing systems and much more.

Series production of flanges and fittings

In addition to customised plastic constructions, Sena Plastics also offers fittings/flanges and other plastic products in various sizes.

CNC processing combined with modern plastic welding technology enables the production of small or large series.

Made of PP/PE/PTFE/PFA/PVC/PA6/PEEK.

Our expertise in pipework and ventilation technology

Sena Plastics offers its customers safe solutions for the management of contaminated exhaust air, which is particularly required in laboratories, in the electroplating, process, environmental and food industries.


We have extensive expertise in the production and assembly of plastic pipes for chemical fluids (ultrapure, toxic, corrosive, etc.). Depending on the conditions of use, various plastics can be used: PVC, PP, PE, PVDF, E-CTFE, PFA or composite materials such as PVC-GFK / PVDF-GFK.
