Demanding building types such as Power plants, large industrial plants, dams or airports often require highly specialized special designs and, if necessary, special designs. They place high demands on the safe and permanent sealing of pipes and cables when penetrating buildings.

As soon as cables have unusual dimensions and special thermal, chemical or physical requirements exist, sealing systems as a special design are the only solution. Only they meet these individual conditions of the building.

DOYMA has the know-how and experience of almost 50 years to develop and produce the best solution for your building. State-of-the-art construction techniques and manufacturing processes as well as professional simulation methods help and create security when using the special DOYMA constructions. And with a 25-year guarantee.

Extreme dimensional accuracy and a consistently high and always the same level of quality ensure the reliable functioning of precision products from DOYMA sealing and fire protection systems: The entire production process is geared towards this. Regularly available series products as well as individual component special designs are manufactured according to these principles.

"Computer integrated manufacturing" (CIM) networks production right from the design phase and makes production extremely fast and efficient. Thanks to CIM, the DOYMA design department is “up close” to manufacturing. The design data flow directly into the corresponding CNC machines. The components of our products are immediately ready to measure for final assembly. In the shortest possible time, our employees take care of the technical order processing, order picking, the production run as well as packaging and loading of the products. 80% of all orders leave our factory on the same day. In most cases, technically demanding special constructions are completed within five working days.

The DOYMA production know-how includes metal, plastic, elastomer and fiber cement processing via water jet cutting units, precision lathes, special rubber cutting systems and a laser cutting system. In final assembly, we configure complex component groups up to the finished product.

The DOYMA machinery includes:

  • Laser cutting machine with fiber technology
  • CNC machines for milling, turning and welding
  • stud welding system
  • MIG / MAG and TIG welding machines
  • Round welding tables • Water jet cutting system
