Case study

Škoda Fabia R5

The project assignment was to produce complete wiring harness of at least the same quality as that of the previous Fabia S2000 that came within the FIA price limit. Therefore, the harnesses were optimized in combination with the above requirements. Thanks to these limits, we again pushed our capabilities forward and produce highly durable and high quality wiring at an affordable price. In the course of the contract, we also faced the requirement to double the volume of deliveries, in which we succeeded thanks to the excellent facilities of the company.

Main Looms

Given the time pressure of the project start-up and frequent technical changes made by the customer, the main harness was still being developed during series production.

ECU Systems

When increasing the resistance of sensors it was also necessary to resolve the electrical control. Each sensor is thus subjected to a functional test, so that we can achieve our standard of 100% electrically tested production.

Production of cable harnesses

Specialists for complex wiring

We are specialists for complex wiring in particular. Each wire in the harness is marked with its connection address (from/to) along its entire length. For the production harnesses we use models so that each harness is identical to the previous one.

Mil Spec Standard

Using Raychem materials, wires with 44 spec. or 55 spec. but also M22759, Deutsch or Souriau motorsport connectors we achieve quality wiring harness, which is required, for example, in the military sector.
