We have come into contact with a plastic water cup produced by a peer company, which uses tritan material. However, after material analysis, we found that the ratio of new and old materials used by the other company reached 1:6, that is, the cost of new materials for the same 7 tons of materials is 38,500 yuan, and The cost of the mixture is only 8,500 yuan, so the normal production cost of a water cup is about 30 yuan. After using the mixture, the cost is reduced by at least 70%. Regarding how to identify the materials of a newly purchased water cup, I have shared it in a previous article. Friends who want to know more please read the articles published earlier on the website.
Type C water cup, this is shared by a reader friend. The other person purchased a branded water cup, which has better quality and material guarantees than other unbranded water cups. However, after using it for less than a month, he accidentally used the water cup. The glass broke, and the mouth of the stainless steel cup was broken. The friend didn’t notice it at first, but when he poured hot water into the cup, he noticed that as the hot water stayed in the cup longer and longer, Long, black liquid kept pouring out from the crack in the mouth of the cup, which instantly frightened this friend. So the friend told us about this and explained the reason for this. What was the black liquid flowing out?
Obviously, this water cup is a cut-corner water cup. First of all, the welding of the cup mouth is not up to standard. Stainless steel water cups will be dropped during production or before leaving the factory. One of the tests is to allow the appearance of the water cup to deform, but welding is not allowed. Location damage, etc. Failure to pass welding is a sign of work-cutting. Secondly, black liquid emerged from the inside of the water cup, indicating that the water cup was not tested and controlled during the production process before proceeding to the next process, and was not tested and cleaned. The normal steps are to clean the water cup through ultrasonic cleaning, thoroughly clean the remaining oil stains, metal shavings, etc. on the water cup, dry it and let it stand, and let it stand upside down for more than 2 hours before entering the next production process.
There are many ways to cut corners and sell substandard water bottles on the market, and we will reveal them one by one in the next few articles.
