1. Flash edge, also known as blank edge, refers to the thin film like resin remaining on the mating surface of the injection molded product, which usually affects the internal and external quality of the electroplated product.
2. Shrinkage: The phenomenon of external stretching of injection molded products due to planning, technical or mold issues. The appearance of electroplated products is affected, and obvious shrinkage is usually not tolerated.
3. Lack of glue/insufficient injection: The phenomenon where molten plastic does not completely flow throughout every corner of the molding space.
4. Flow pattern: A defect resembling ripples caused by plastic material flow issues. Affects the appearance of the finished product, and flow patterns are usually not tolerated on the main surface of the finished product.
5. Silver streaks: Silver streaks formed on the surface of a finished product due to abnormal injection molding materials or techniques, resulting in bubbles or eruptions. Silver thread is usually not tolerated.
6. Deformation: The deformation of the finished product caused by improper production or placement, and the deformation of the electroplated blank is not tolerated.
7. Fused wire: a joint wire made of molten plastic that affects the appearance and function of the finished product.
8. Cold material: injection molding technology poses a serious problem, as it will show traces on the surface of the finished product, affecting the adhesion and appearance of the coating.
9. Convex points: mostly composed of defective molds, which affect the appearance of the finished product.
10. Pits: usually refer to indentations that affect the appearance of the finished product.
11. Processing damage: such as scratches, scratches, bumps, scratches, excessive trimming, etc. Affects the appearance of the finished product, and the level of tolerance depends on the product.
