Components engineered by HANSA‑FLEX

Orders for our development services come about in various ways. HANSA‑FLEX employees identify a need in the course of their normal work, strategic considerations suggest expanding our portfolio or customers place a specific development order. In every case, the first step is an analysis of the customer’s requirements. What should the new development achieve? What is its purpose? Then our team discusses preliminary approaches we could take to arrive at the best solution in terms of technical and cost-effectiveness.

From these preliminary considerations, HANSA‑FLEX comes up with specific proposals for action and eventual implementation. Engineers then create sophisticated 3D models on the computer. Still in the virtual world, initial trials help to ensure that the process is designed to be as efficient as possible. Using state-of-the-art finite element methods (FEM), our engineers check whether the component on the drawing achieves the required physical properties. The software calculates how the component performs under specific loading such as compression, tension or temperature fluctuations.

Following success in the virtual trials, the component has to produce its predicted performance in practice. This requires us to manufacture several prototypes. Tests in our in-house laboratory confirm whether the properties fundamental to the required hydraulic performance have been achieved. On burst pressure test benches, we check whether the component withstands the required pressure loadings including safety reserve. In the impulse pressure test, we ensure that the component can withstand an adequate number of alternating load cycles and pressure peaks.

Once the prototypes have proved that the performance of the component meets the requirements, it is released for series production. However, the quality requirements at HANSA‑FLEX are so high that this is not the end of testing for a new product. The first products from the preliminary series are subject to more tests in the laboratory. In our practice-proven Production Part Approval Process, we carefully check whether important features such as dimensions and material choice comply with the specification. Only after this final stage does the new article receive approval for delivery to our customers.
