Our company has stainless steel brackets. Due to the incorrect radian of the arched cylindrical part, the angle of the product when installed in the L part is greater than 9 1 degree, which was complained by customers. Answers can solve problems. If the customer is strict, he will only give in at most. Because the size must be changed. Some foreign products are well made and beautiful. In fact, they not only solved the problems they found, but also made the products very detailed, even the small details would be well done. For example, we have a problem similar to yours. Our solution is to open a plastic mold. It is sometimes more difficult to grasp the size of this plastic mold than to open a product mold, because it will be set to rebound count and so on. I think in order to increase the added value of products, we must consider this aspect more, and it is best not to deal with it temporarily unless we have to.
