Manufacturing bursting discs involves stamping, deep drawing, scoring, laser cutting and welding and, above all, testing - destructive bursting tests, dimensional testing, visually and mechanically, sealing tests and alternating load tests. The documentation, the labelling: everything has to be inspected in great detail, because this is essential for bursting discs - irrespective of whether the batch size is one unit or one hundred thousand.
With our extensive know-how, experience and the necessary equipment, we are geared up for precisely this work.
- The optimum organisation of the material warehouse is also crucial. We guarantee traceability and absolutely exclude the possibility of any mix-up of materials. The high-quality, thinly rolled starting materials are sourced from a few renowned manufacturers, with whom we have been working for a long time. Since the delivery times are often very long, we endeavour to always keep many of the qualities in stock.
- Many bursting discs have to be welded on. We are equipped with laser welding machines and are able to carry out capacitor discharge welding. We are happy to advise our customers on the optimum welding process. We are able to demonstrate the quality of our weld joints with the helium leak test, pressure loading and metallographically.
- The scoring of thin sheets for reverse buckling bursting discs and rupture discs is a demanding technology. We are able to cope with the demands of this technology with our own tool manufacture and also with special presses, in order to achieve the required precision to within a thousandth of a millimetre. We also use visual measuring processes in order to measure the extremely fine and narrow scores.
