3.81 Electronic Wire Harness Precision Terminal Wire Harness Processing

Details

Electronic wire harnesses are key components in electronic devices for transmitting signals and power, composed of multiple wires arranged rationally, insulated, and assembled with connectors. Our electronic wire harness processing service focuses on high-precision, high-reliability customized production to meet various electrical connection needs. Product features include high-quality copper conductors and eco-friendly insulation materials, offering excellent conductivity and strong durability; support for twisted-pair electronic wire harnesses to effectively resist electromagnetic interference and ensure signal stability; support for non-standard customization with rapid prototyping and mass production based on customer drawings or samples; strict quality inspection processes including continuity testing, withstand voltage testing, and visual inspection; modular production to shorten lead times and reduce overall costs. Technical specifications: wire gauge range AWG 18~32, rated voltage ≤300V, rated temperature -40℃~+125℃, insulation materials optional PVC, PE, TPE, etc., compatible connector types JST, Molex, Hirose, etc. Application scenarios widely used in household appliances (air conditioners, washing machines), automotive electronics (on-board sensors, lighting control systems), industrial control (PLC, servo drives), communication equipment, and medical devices requiring high connection reliability.

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.

01
Step 1 Review Wire Harness Specifications

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.

02
Step 2 Wire (Cable) Cutting

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.

03
Step 3 Wire Pre-Processing

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.

04
Step 4 Terminal Crimping

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.

05
Step 5 Connector Assembly Processing

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.

06
Step 6 Wire Labeling

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.

07
Step 7 Wire Harness Visual Inspection

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.

08
Step 8 Electrical Characteristics Testing

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.

09
Step 9 Finished Product QC & Image Recording

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.

10
Step 10 Packaging & Shipping

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.
