Needing to get your product to market, but wire harnesses are still missing – and it’s hard to find time to develop them beyond the basics?
Consider it solved! EFC manufactures wire harness prototypes based on drawings or even a written description scribbled in the margin of a notebook. Our technical sales specialist will go through all open questions with you, including quality assurance, documentation, and testing methods. We have expertise in every stage of wire harness manufacturing, so you don’t have to spend time figuring it out yourself. This saves you time and helps you avoid costly mistakes. We also react quickly – in the best case, our customer has had their product in production just two weeks after the first contact.
