Component Test Rig 5

Test bench for component testing

This component-test bench can be used to test individual components, such as water or oil circuits.
This method has got several advantages: on the one hand it helps saving time and money and on the other, it offers the chance of identifying possible potentials or critical points, nevertheless.

Construction Design of completely new engines or the enhancement of existing power units –inventive spirit, courage, extensive team work and our huge wealth of represent the basis for innovative results.
Manufacturing Precision components or the refinement of existing components, single copy or small-batch series, solid material or cast material – a diversified service range thanks to an ambitious mix of know-how and new developments.
Quality management Out there on the racetrack, the smallest mistake can be crucial. Therefore, special emphasis is placed to a gapless and absolutely precise quality control. No part will be installed without having been subjected to an extremely strict examination.
Engine manufacturing The engines are individual custom products and are assembled in the heart of the company by a highly qualified team. Here, quality instead of quantity represents the yardstick.
Test bench Here, the process represented by development and design, production and manufacturing comes full circle. On the test rigs, the components or the entire project have to definitively demonstrate if they meet the highest standards.
