  Exterior visual effect inspection includes the flatness and clarity of the vacuum bag inspection and other new items. The key is to test whether the surface layer has significant scratches and needle holes, sealing has zero pollution, etc.

  2: Check the flatness of vacuum bag. The vacuum bag is placed alone on the leveling table. If the surface layer is bent, warped outward or arched inward, it indicates poor flatness, and on the contrary, it indicates excellent flatness. The reason for the poor flatness generally has the following aspects: the temperature of the production bag is higher, has destroyed the in-situ stress tensile strength of the composite bag layer; Unscientific structure; The thickness of raw materials is not uniform.
