How do we control the quality of wire harness products

Quality control is an essential aspect of any business that aims to provide top-notch products or services. It encompasses a range of processes and activities that are put in place by companies to ensure that their offerings meet or surpass the desired quality standards. These measures involve closely monitoring and evaluating various aspects of the production or service delivery process, with the aim of identifying and rectifying any deviations or defects. The ultimate objective of quality control is to consistently deliver high-quality products or services that not only meet but exceed customer expectations. This requires a commitment to excellence at every stage, from design and development through to manufacturing, distribution, and after-sales support.

To achieve this goal, businesses must implement rigorous testing procedures, employ skilled personnel who are trained in quality assurance techniques, use state-of-the-art equipment and technology where appropriate, and maintain strict adherence to industry regulations. By doing so, they can build trust with customers while also enhancing their reputation as a reliable provider of superior goods or services.


Here are 7 aspects of how we control wire harness products quality:


1. Certificates

We are proud to announce that we have successfully achieved 4 major certifications, which demonstrate our commitment to excellence and quality. These include the highly respected UL certification, which recognizes our products' safety and reliability; the ISO9001 quality system certification, which confirms our adherence to strict international standards for quality management; the IATF16949 certification, a rigorous automotive industry standard that ensures our products meet the highest levels of performance and durability; and finally, the CE certification, which demonstrates compliance with European Union regulations for health, safety, and environmental protection. With these certifications under our belt, we can confidently say that we offer some of the most reliable and high-quality products on the market today.



2. Laboratory

In order to ensure the quality and reliability of our products, we have taken great care in setting up our very own test room. This state-of-the-art facility allows us to conduct a wide range of tests that are essential for ensuring that every component meets our rigorous standards. One such test is the temperature test of the jacket of the wires and cables. By subjecting this critical component to extreme temperatures, we can determine its ability to withstand harsh conditions and maintain optimal performance over time. Another important test is the Strain Relief (SR) swing test of the molding. This involves subjecting each molded part to repeated swings in order to assess its durability and resistance to wear and tear. We also perform plug and pull tests on all terminal plastic parts, which helps us identify any potential weaknesses or defects before they become a problem. Additionally, we conduct tension tests on all terminal presses, ensuring that they meet our strict requirements for strength and reliability. Finally, we use quadratic measurement techniques to carefully analyze each component's dimensions and ensure that it conforms precisely with our specifications. All these measures combine together seamlessly in order for us deliver high-quality products you can trust.



3. Supplier audit

We recognize the importance of maintaining high standards in our procurement process, especially when it comes to sourcing raw materials. To ensure that we consistently meet these standards, we are implementing a rigorous supplier screening system. This system will be integrated into our existing procurement process after a thorough qualification assessment. By doing so, we can guarantee that all suppliers who provide us with raw materials have been thoroughly vetted and meet our strict criteria for quality and reliability. Our goal is to ensure that every single raw material used in our production processes meets or exceeds the specifications set forth by our company. This not only ensures consistency in product quality but also helps us maintain compliance with industry regulations and best practices. We understand that this may require additional time and resources on both ends of the supply chain, but we believe it is worth the investment. By working closely with our suppliers to establish clear expectations and guidelines, we can build stronger relationships based on trust and mutual respect. In short, implementing a strict supplier screening system is just one way that we are committed to delivering products of exceptional quality while upholding ethical business practices at every step of the way.

4. Imcoming quality control (IQC)

To ensure the highest quality of our products, we must implement a strict incoming inspection system. This means that every batch of materials will undergo sampling inspection to guarantee their compliance with our rigorous standards. Any materials found to be unqualified will be resolutely returned for re-production. By implementing this process, we can rest assured that only the best materials are used in our production line. We take pride in delivering top-notch products to our customers and believe that this level of attention to detail is essential in maintaining their trust and loyalty. Our commitment to quality extends beyond just the finished product - it starts with the raw materials themselves. By carefully inspecting each batch before use, we can identify any potential issues early on and prevent them from affecting the final product.
