2. Weld lines---This is also a common defect of plastic parts. The gas lines on the surface of plastic parts are a little different from the surrounding color textures, which can be distinguished by naked eyes.
3. Shortage of materials---The shortage of plastic parts is generally caused by insufficient glue during injection molding, which is manifested as incomplete corner shortage of plastic parts.
4. Skin front---that is, the rough edges of plastic parts, which is also a common defect. The rough edges of plastic parts are generally small, and some low-end plastic products can often see skin front.
