Inspection rules for school uniform manufacturers

In fact, there are many different tests for school uniforms, all of which are designed to effectively improve the quality of school uniforms，this inspection is usually carried out by the quality control personnel on the assembly line or by the team leader to confirm the quality before finishing and to facilitate timely modifications to the product. For school uniforms such as blazers, which have high quality requirements, quality checks and controls are also carried out on the components before they are combined. For example, an inspection and control should be done before connecting the front piece with the back piece after the process of pockets, provinces and splicing on the front piece is completed; the sleeves, collar and other parts should also be inspected before they are combined with the body; such inspection work can be done by the personnel of the combination process to prevent parts with quality problems from flowing into the combination processing process. With the addition of semi-finished product inspection and component quality control points, it may seem like a lot of wasted manpower and time is invested, but this will reduce the amount of rework and ensure quality, bearing in mind that the investment in time costs is very high.
