1. Warpage deformation: deformation of plastic products caused by internal stress difference or poor cooling during injection molding.
2. Gate markings: There are discernible rings around the gate. If the center gate is used, it is the center circle, and if the side gate is used, it is the concentric circle.
3. There is a smashing area in the sharp edge material flow area: the surface of the product is very good, until the sharp edge, the sharp surface appears on the surface and the surface is rough.
4. Voids: The voids inside the article appear as round or elongated bubbles, which often occur in relatively thick articles, especially in the thickest areas.
5. 邃 bubble: bubbles generated inside the plastic cause the surface of the product to produce a convex shape
6. Black spots or black lines: due to raw materials mixed with foreign bodies. After the injection molded parts are formed, spots appear on the surface of the product, or stay at high temperatures for a long time to cause decomposition, and black streaks or black spots appear.
7. Spray pattern: When the melt enters the cavity, there is a serpentine-like pattern at the front end of the fluid. It often occurs in the mold of the large chess cavity, and there is no direct contact with the mold or no obstacles when the melt is filled.
8. Recording pattern: A deep groove can be seen in the direction of the entire flow and even at the end of the flow path.
9. Weld line: A kind of linear trace on the surface of plastic parts is injected or extruded. If the strands meet in the mold, the melts are not completely fused at the interface, and they cannot be welded together to form a fusion. Imprinting, affecting the appearance quality and mechanical properties of plastic parts
10. Dark spots, black lines, embrittlement, burn marks, and discoloration.
a. Black spots and black lines are dark spots or dark stripes on the surface of plastic parts, and brown spots or brown lines refer to the same type of flaws.
b. Embrittlement is the cracking of the material, which shortens the molecular chain and lowers the molecular weight, resulting in a decrease in the physical properties of the plastic part.
c. Burn marks are dark or black dots that are close to the end of the flow path or the wind zone.
d. Fading refers to the change of plastic parts from the original plastic color.
11. Flashing edge: The thin part of the parting line is the excess of the plastic overflow mold clamping surface and the insert in the injection molding process, and remains on the plastic product after cooling.
12. Dent: The dent is generally caused by a local increase in the shrinkage of the product due to an increase in the wall thickness of the plastic article. It is the local internal contraction caused by the gate sealing or the shortage of injection.
13. Lack of material (underfill): a gap formed on the surface of the part due to insufficient pressure or trapped air during filling.
14. Top white: the surface of the surface is whitish, which is the external part of the injection molded part. The whitening and deformation caused by the singulation of a part of the molecular structure caused by the rearrangement of the mold, usually occurring at the other end of the ram.
15. Chromatic aberration: refers to the actual product color and the sample sample color or swatch contrast exceeds the allowable value
16. Cold spot: refers to the fog or bright color of the near gate of the workpiece or the curved scar from the gate as if it were attached to the gate.
17. Cracking and whitening: The relatively obvious micro-cracks on the surface of the plastic part are called cracks. The frost-like cracks similar to the cracks are called whitening, and the cracks and whitening are fine cracks without cracks. Environmental stress cracking occurs when a plastic part is exposed to a chemical environment or under stress.
18. Silver wire: the needle-like silver white color of the surface of the plastic part in the direction of the flow.
19. White line: The whitened stripe-shaped deformation zone of the polymer due to stress concentration under the tensile stress. These stripe plane areas strongly reflect visible light, forming a silver-white luster on the surface of the material, commonly known as white line.
