FAQ
Q: Where is your factory?
A: Our factory is located in Dongguan City, Guangdong Province, China. Welcome to visit us!
Q: How long is the life of your wires and cables?
A: The life of our wires and cables is no less than 30 years.
Q: What is your quality assurance process?
A: We will select and inspect the raw materials, and conduct strict quality inspections on each batch of raw materials. During the production process, the factory usually uses automated equipment and online detection systems for real-time monitoring. For example, the diameter of the copper wire, the thickness of the insulation material, and the twisting process during the wire drawing process all need to be precisely controlled. At the same time, we regularly take a certain number of wire and cable samples for inspection. These inspections include but are not limited to tests such as size, insulation resistance, conductivity, and mechanical strength. Each batch of wires and cables produced will be fully tested before leaving the factory. If quality problems are found in the product testing, the factory will take "traceback" measures to find the root cause of the problem and correct possible deviations in the production process. After production is completed, all wire and cable products will undergo a final quality inspection. In the packaging stage, the wires and cables will be properly packaged according to the specifications to ensure that they are not damaged during transportation. In addition, we have a professional after-sales team to respond to customer feedback and complaints in a timely manner to ensure that problems encountered by users during use are solved in a timely manner. In addition, the factory will regularly visit customers to collect product usage feedback and further improve product quality.
