Our company is a strategic supplier of a French global company. The customer has long spent a lot of money and time on the uncontrollable hardness of aluminum profiles. To this end, we discussed technical difficulties with a number of profile companies and solved the time waste caused by the cost of "non-destructive testing" by adjusting the formula of raw materials. We provided quality assurance from the source, thereby reducing product losses during the processing process and passing this cost saving on to customers, thus achieving a win-win cooperation. The cooperation has lasted for ten years, and 5 million products are delivered to global customers each year.
