Mr. Kong’s company recently purchased a batch of weather stripping for doors. Because it is a new supplier that the purchaser has changed privately, they are also very careful about the incoming materials. As a result, they found that the weather stripping for doors came back this time with gloss and resilience. Not as good as before. Therefore, Mr. Kong had to find his old partner Aoqun again to help analyze the cause.

After Ms. Kang from Aoqun learned of Mr. Kong’s feedback, she asked Mr. Kong to send a sample over to make a careful analysis of the material and craftsmanship. It turned out that the weather stripping for doors that Mr. Kong received now had a little nylon content, but the material There will be a pungent plastic smell after burning, and the burning smoke is also black. The authentic pure nylon will taste like nylon after burning, but it will not be pungent; the outer layer of the flame is yellow, the inner layer is light blue, and the smoke after extinguishing is white.

From this, it can be determined that Mr. Kong’s buyer bought inferior weather stripping for doors. Ms. Kang took the above test video to Mr. Kong and patiently explained to him the benefits of using high-quality weather stripping for doors, and it can pass the latest EU standard SVHC test, while the inferior weather stripping for doors cannot even be RoHS 10 by. Subsequently, Mr. Kong ordered 15,000 meters of weather stripping for doors from our company again.

Later, Mr. Kong told me when chatting, thanks to our timely help to test and find the problem. It turns out that his batch of weather stripping for doors is for export. The customer just happens to have very strict requirements for the EU standard test. Not only is it required to provide a report, but the brush will be sent for a second inspection before confirming the receipt and payment. Since then, Mr. Kong has become one of Aoqun's stable and high-quality customers.
