Wire Harness Manufacturing Specifics

As a wire harness manufacturer with an impeccable track record, we understand the importance of pricing, quality and in-time delivery. Therefore, our production, engineering, quality control, logistics, procurement, administrative and sales departments are tightly integrated together. Maintaining open and clear communication lines allows us to continuously fulfill the high expectations of our clients.

Our outsourcing of raw materials and components comes only from certified or client-specified sources. We also have an internal wire production line which helps our clients to gain additional savings.

Having an in-house team of one of the most qualified engineers in the industry allows us to develop your custom wire harness prototypes quickly and successfully submit them to you.  Upon your request, our engineering department can work closely with you to help you in the development of such prototypes.

Wire Harness Manufacturing Capacity and Quality

We have over 700 employees and occupy over 190,000ft2 of modern manufacturing facilities. Our wire harness manufacturing process has achieved one of the highest efficiency standards in the industry due to modern equipment, ongoing training and the latest technologies.  Modern wire harness manufacturing planning combines both manual and automated production processes to achieve superior quality and cost efficiency. An expert wire harness manufacturer understands that fully automated production lines will not deliver consistent quality of products due to the nature of wire harness manufacturing. Although in theory this is possible, the reality is that to maintain the highest quality standards in wire harness assembly through full automation would be cost prohibitive.  Therefore we pay extra attention to our workers training and integrity of our production operations.

Through the combination of well-tuned machinery and skilled manual labor we deliver consistent quality, low pricing and short lead-times.
