Processes Involved in Custom Wiring Harness Manufacturing
Depending on the design, wire harnesses can be manufactured in different ways. However, it all begins with design and prototyping. Engineers develop custom wiring designs and prototypes before the actual manufacturing process to deliver power or data efficiently. The process eliminates possible risks, makes it easier to decide on the components and materials, and allows future-proof wiring solutions in areas that may require it.
Most of the manufacturing processes are done in the production and assembly stages. Here, components for large parts requiring high customization levels are assembled manually since manual assemblies make it easier to address possible geometric issues in the wire harness.
Below are the next steps involved in the wire harness manufacturing process:
Crimping is a necessary manufacturing process in wire harness production. It is the process of joining pieces of metal by deforming one or both components to hold each other inside the harness. The process allows connecting a terminal to a wire conductor without having to undergo soldering, reducing the risk of corrosion.
In this step, wires are cut to size depending on the initial design or prototype of the wire harness assembly. A wire-cutting machine is utilized to standardize the process.
Coiling makes it possible to keep long wires together and intact. It also aids in minimizing stress on the wire by providing allowances for movement, such as bending and stretching.
Inserting the wire into the connector after crimping contacts to the end of the wire is part of the connecting process.
In the sub-assembly stage, build components are integrated into different component assemblies to create a large segment of the final product. Manufacturing sub-assemblies makes it easier to assemble the final product, which saves time and resources for OEMs.
Soldering is joining different wires and sub-assemblies with a metal alloy to create a larger end product or component.
Removing the outer protective sheet of the wire harness without cutting the components beneath describes the stripping process. Stripping enables the electrician to expose the wire to create new connections or to do repairs.
In the terminal application, the wire harness is connected to the junction connector, which functions as a wire connector. The terminal serves as the connection between the plug and the wire. In the automotive industry, terminal crimping is the link in the production process of automotive wire harnesses.
Ultrasonic Wire Welding
Ultrasonic wire welding is the technology used in creating wire harnesses in different industries and is the ideal welding type for connecting plastics and metals. It is the process of combining multiple wires to a terminal or conductive contact material. The connection is achieved with high-frequency ultrasonic vibrations applied to the components to create a solid weld.
