Wire harness assemblies are integrated arrangements of cables within insulated sleeving or jacketing. These assemblies include multiple terminations in complex arrangements for flexible applications. PGF Technology offers wire harness assembly manufacturing built to spec through our extensive in-house termination, cutting, crimping, and twisting capabilities.
Complex harnesses require detailed instruction and preparation. The PGF team implements digital work instructions with step-by-step procedures to construct the best wire harness assemblies for your project.
Crimping and soldering assembly methods for wire harnesses offer different techniques to achieve secure connections, proper insulation, and protection. The choice of method depends on factors such as the application requirements, wire type, connector type, and desired level of durability and aesthetics. The quality of an electrical connection can drastically impact the reliability and performance of the entire system, making it crucial to select the proper joining method.
Mechanical force compresses connectors or terminals onto the stripped wire ends, creating a secure electrical and mechanical connection. Unlike soldering, the process does not require heat and is often the preferred choice for most applications due to its speed and ease of use.
A soldering iron melts a small amount of alloy around two wires, and as the material cools, it forms a strong, electrically conductive permanent bond between the two groups of wire strands. Soldering requires the use of heat and heat-shrink tubing to insulate and protect the connection.
At PGF Technology, our wire harness manufacturing services involve assembling the following components.
The wire conductors form the core layer of a wire harness assembly. These are individual wires that carry electrical signals or power between components.
The insulation layer surrounds each wire conductor, providing electrical insulation and preventing the wires from coming into contact with each other or external elements. It helps maintain signal integrity and prevents short circuits.
In applications where electromagnetic interference (EMI) protection is required, a shielding layer is added. It consists of conductive material, such as metal foil or braided wire, which helps minimize the impact of external electromagnetic noise on the signals transmitted through the wires.
The outer jacket is the final layer of a wire harness assembly. It encases the wires and provides mechanical protection against abrasion, moisture, chemicals, and other environmental factors. The outer jacket is typically made of materials like PVC, TPE, or Polyurethane.
Given the complexity of wire harness assembly manufacturing, relevant design for manufacturability (DFM) experience is essential to meeting your specific requirements. At PGF, creating a wire harness assembly typically involves the following key steps:
Cut the wires to the required lengths based on the design specifications. Remove the insulation from the ends of the wires using wire strippers to expose the conductor.
Attach terminals or connectors to the stripped wire ends using a crimping tool. Crimping creates a secure mechanical and electrical connection between the wire and the terminal. Apply solder to the stripped wire ends and the terminal or connector, and heat the joint with a soldering iron to create a permanent connection.
Insert the crimped terminals into their corresponding housing or connector. Secure the terminals in place by locking or latching them within the connector housing.
Arrange the wires in the desired configuration, following the routing paths specified in the design. Use cable ties, tape, or sleeving to bundle and organize the wires together, ensuring a neat and organized appearance.
Use specialized equipment to test the continuity and integrity of the wire connections, verifying that the assembled harness functions properly. Inspect the wire harness assembly for any physical defects, such as loose connections, exposed wires, or incorrect routing.
Apply a braided sleeve or heat-shrink tubing over the wire harness to provide additional protection against abrasion, mechanical stress, and environmental factors. Apply heat to the heat-shrink tubing, causing it to shrink and conform tightly around the wires, providing insulation and strain relief.
Attach labels or markers to identify individual wires, terminals, or specific functions, aiding in installation, maintenance, and troubleshooting.
Conduct a final visual and functional inspection to ensure that the wire harness assembly meets all the required specifications and quality standards. Package the assembled wire harnesses appropriately for storage, transportation, or direct installation in the intended devices or systems.
At PGF Technology, our skilled and knowledgeable team conducts routine inspections and continuity testing to identify the following types of potential defects in manufactured components:
With advanced testing equipment, we can verify the integrity of wire connections in our custom cable assemblies, ensuring optimal performance and reliability.
WIRE HARNESS / CABLE PROCESS
Each wire termination is subjected to a calibrated tensile force to verify the mechanical integrity of every crimp joint before the assembly ships.
Using our Cirris tester, every conductor path is electrically verified — ensuring no open circuits, shorts, or miswired connections reach your product.
Inspectors review each completed harness for routing accuracy, connector seating, insulation condition, and proper labeling across the full assembly.
PCBA PROCESS
High-resolution cameras automatically scan every completed board, detecting solder bridges, missing components, and misalignments without manual intervention.
Trained technicians manually review each board for workmanship quality, component orientation, and assembly details that automated systems may not catch.
One transposed connection can make an entire assembly non-functional — or damage downstream equipment. Continuity testing catches miswiring at the source.
Every electrical pathway is verified to confirm complete circuit continuity and proper signal flow across all connections on the finished board.
All of our Made-in-the-USA complex cable assemblies adhere to strict regulatory standards. The following certifications represent our commitment to providing the highest level of safety, quality, and reliability:
After conducting a final functional and visual inspection, we deliver products for seamless installation into the intended devices or systems.
Wire harness assemblies are crucial components in vehicles, aircraft, manufacturing equipment, and electronic devices, providing reliable and organized electrical connections for power distribution, signal transmission, and control systems. High-quality custom wire harness assemblies play a pivotal role in ensuring efficient and safe electrical system operation.
Most wire harnesses are made with a specific application or device in mind for optimal functionality and safety. The most important factors for you to consider during the design process are space requirements, installation preferences, and power demands of the equipment or device in which the harness will be used. Other factors to consider include temperature, chemical exposure, humidity, flexibility, and color preferences. In general, the length of time required to manufacture the wire harness assembly will depend on the design’s complexity.

While the terms are often used interchangeably, there is a distinct difference in application. A wire harness is typically a group of wires bundled together using tape, cable ties, or sleeving to organize a system and provide basic protection—ideal for internal applications like those inside a control panel or a medical device. A cable assembly usually involves a more rugged, protective outer jacket (like vinyl or thermoplastic rubber) designed to withstand external environmental stressors like moisture, abrasion, and heavy friction.
Managing complexity is where PGF excels. We use digital work instructions and specialized routing boards (formboards) to ensure every breakout and termination is placed with 100% accuracy according to your schematics. Our engineers review your designs for “Design for Manufacturability” (DFM) to ensure that even the most intricate, multi-branched harnesses can be produced efficiently and reliably.
