In the context of the widespread application of modern industrial and electronic equipment, the quality of wire harnesses directly affects the stability and safety of equipment. As a professional wire harness manufacturer, we are well aware of the importance of ensuring the quality of wire harnesses and have taken a series of strict measures to ensure the accuracy and reliability of our products. In this article, we will introduce in detail how we pass 23 strict tests before leaving the factory and follow international standards to ensure the quality of wire harnesses.
Strict quality control process
- Raw material testing
Our quality control starts with the most basic raw materials. All raw materials entering the warehouse must undergo strict testing to ensure that they meet the standards we set. Only qualified materials can be put into production.
2. Wire conductivity test
Conductivity is one of the important criteria for testing the quality of wire harnesses. We conduct conductivity tests on each batch of wires to ensure that their conductivity is excellent.
3. Wire mechanical strength test
Wires must have a certain mechanical strength to cope with various application environments. We use a tensile testing machine to test the tensile strength of the wires to avoid failure of the wire harnesses due to mechanical damage.
4. High and low-temperature performance test
Wire harnesses must maintain stable performance in different environments. We conduct high-temperature and low-temperature tests to test the performance of the wire under extreme temperature conditions.
5. Anti-aging performance test
The anti-aging performance of the wire is related to its service life. We evaluate the anti-aging ability of the wire through accelerated aging tests.
6. Insulation performance test
Ensuring the insulation performance of the wire harness is the key to preventing short circuits and leakage. We use professional equipment to test the insulation performance of the wire.
7. Corrosion resistance test
In a specific environment, the wire harness must be corrosion-resistant. We use corrosion resistance tests to ensure that the wire harness material is not corroded under harsh conditions.
8. Cable crimping test
The wire harness involves a large number of crimping processes during the assembly process. We inspect each crimp to ensure that the crimping is firm and does not loosen or fall off.
9. Wire harness welding test
The welding quality of the wire harness directly affects its electrical performance and mechanical strength. We use X-ray microscopes to perform non-destructive testing on the welding points to ensure that the welding quality meets the standards.
10. Wire harness forming test
The wire harness forming must meet the specification standards. We use special equipment to test the size of the formed wire harness to ensure the accuracy of the wire harness size.
11. Electrical test
To ensure that the electrical connection of the wire harness is normal, we conduct a full inspection of the formed wire harness to test its continuity and resistance value.
12. Bending resistance test
The wire harness needs to be bent many times during use. We use the bending resistance test to test the stability of the wire harness during bending.
13. Wear resistance test
The wire harness needs to have good wear resistance. We use a wear resistance test to ensure that the wire harness is not easily damaged during friction.
14. Waterproof performance test
The wire harness needs to have good waterproof performance when used in a humid environment. We use a waterproof test to test the performance of the wire harness after being immersed in water.
15. Flame retardant performance test
To ensure the safety of the wire harness under fire conditions, we conduct a flame retardant performance test on the wire to ensure that it meets the flame retardant standard.
16. Connector performance test
The performance of the connector directly affects the connection reliability of the wire harness. We perform plug-in and pull-out tests on each connector to ensure that it has good contact and no poor contact.
17. EMIRFI shielding performance test
In an environment where electromagnetic interference(EMI)and radio frequency interference(RFI)are frequent, the wire harness must have good shielding performance. We use special instruments to test the EMIRFI shielding effect of the wire harness.
18. Wire harness weight detection
The weight of the wire harness must meet the design requirements. We use a precision electronic scale to weigh the finished wire harness to ensure that it meets the standards.
19. Appearance inspection
A comprehensive inspection of the appearance of the wire harness is carried out to ensure that it is free of damage, scratches, and stains and that the appearance is neat.
20. Packaging inspection
The wire harness must be well protected during transportation. We inspect the packaging to ensure that the packaging materials and methods meet the requirements.
21. Label inspection
Each wire harness must have a clear label. We check the wire harness label to ensure that its content is accurate and the font is clear.
22. Environmental testing
The wire harness material must meet environmental requirements. We use professional testing agencies to test the environmental performance of wire harness materials and meet international environmental standards such as RoHS.
23. Factory inspection
All qualified wire harnesses are subject to final factory inspection. We conduct comprehensive inspections on wire harnesses through random sampling to ensure that the products are 100%qualified.
Follow international standards
We strictly follow international quality management system standards including ISO 9001 and IATF 16949, as well as international certification standards such as UL, CSA, CE, and RoHS.Through these standards, we ensure that each product meets the high-quality requirements of the global market.
As a professional wire harness manufacturer, we ensure the excellent quality and stable performance of our products through a series of strict quality control measures and 23 specific tests. We always adhere to quality as the basis for providing customers with high-quality and high-reliability wire harness products. In future development, we will continue to maintain rigorous quality control standards and strive to provide customers with the best quality wire harness solutions.
