The full name of QC is quality controller, who is responsible for inspecting products and controlling quality. As the name implies, clothing QC is the person who controls the quality of clothing. According to my understanding, QC and inspector are two different concepts. The focus of QC is control, and the purpose is to let the company get good quality products. Inspectors only judge whether a batch of goods is qualified or unqualified through inspection to prevent the company from receiving unqualified products. But now most people confuse QC with inspector. We also call it QC here. Some companies only conduct a final inspection); Before each garment is shipped; Some have to check the mid-term inspection and final inspection); Check at least once; Some even need to carry out quality control in the whole process of garment production, and carry out early inspection or online inspection many times to find and solve problems as soon as possible.
