Wire Harness Customization & Processing Flow
From requirement confirmation to finished product delivery, 10 processes with strict checks at every stage ensure each wire harness meets the highest quality standards
We have comprehensive wire harness customization and processing capabilities, covering the entire process from requirement confirmation to finished product delivery. The following is the standard wire harness processing workflow, with strict quality control standards at each step to ensure product consistency and reliability.
Confirm Requirements, Start with Precision
Before production, engineering confirms the specifications based on the customer's drawings and specifications. Any pending items are communicated with the customer to resolve production questions before finalizing the manufacturing process, ensuring every step is accurate.
Cutting Precision Down to the Millimeter
Cut wires (cables) to the required length and coil them. Operators carefully verify the specifications on the production work order before cutting, using calibrated advanced equipment to ensure the processing quality of each wire.
Professional Stripping, Precision Pre-Soldering
Remove the wire jacket (outer sheath) and any unnecessary fillers. Use a professional pneumatic wire stripper to strip the jacket, then perform pre-soldering. Adjust the equipment precisely according to each wire specification to ensure zero damage to the core conductor.
Secure Connection, Reliable Transmission
Crimp the terminal to the wire (cable) core conductor. Use a professional terminal crimping machine, with dedicated crimping dies for different terminals. Strictly adjust the machine and check the crimping specifications before operation to ensure each terminal connection is firm and reliable.
Fine Assembly, Quality Assurance
According to the engineering drawing, sort the crimped core wires, assemble them into the connector housing, and reinforce the wire harness strength. All processing methods strictly follow the engineering drawing and SOP, using specialized tools to ensure consistency.
Full Traceability at a Glance
Attach labels containing information such as specifications, ID, and serial number to each customized wire. Labels help assembly personnel quickly find the corresponding interface and facilitate future traceability of production history, enabling full-process digital management.
Self-Inspection & Peer Check, Layered Control
After assembly, perform self-inspection during wire harness production based on the production work order drawings and dimensions, ensuring all manufacturing details are confirmed. Every step is recorded, and every link is traceable.
Four-Wire Testing, Zero Defects Outgoing
All completed wire harnesses undergo continuity testing, resistance measurement, wire position measurement, and insulation resistance testing using a four-wire electrical tester. They are only released after confirming normal electrical characteristics, ensuring each wire harness meets design standards.
Digital Archiving, Traceable Quality
Record and archive images of the finished wire harness. Production engineering data and appearance are digitally archived for easy future review, modification, or addition. Digital management ensures precise reproduction of wire harnesses with the same specifications.
Safe Protection, On-Time Delivery
Carefully package with cushioning materials to ensure no damage during transportation, and ship according to the specified method. Full tracking from packaging to logistics ensures products are delivered safely and on time to the customer.
