1. Weld marks
(Commonly known as: clamped water pattern; other names: clamped line, clamped line, and glue line)
definition
In the injection molding process, when two streams meet, the interface is not completely fused and the traces are caused.
2. Sink marks (common name: shrinkage; other names: none)
definition
When the plastic part is cooled and solidified in the mold cavity, the surface of the plastic part is dented due to the uneven wall thickness of the plastic part, insufficient injection pressure, insufficient cooling time, etc.
3. Technical term: none (commonly known as: air pattern; other names: none)
definition
Due to the structure of the injection mold, the molding process and the material, the plastic is affected by the pressure and the flow velocity in the mold cavity, and the material flow traces on the surface of the plastic part are produced.
4. Technical term: None (common name: material flower; other name: flush flower)
definition
Silver-white stripes formed on the surface of plastic parts by low-molecular volatiles, moisture and other gases
5. White seal (common name: white; other names: top white, pull white, drag high)
definition
Part of the plastic part is subjected to external pressure to rearrange or break part of the molecular structure, causing local white printing on the surface of the plastic part.
6. Technical term: None (commonly known as: surface protrusion; other names: top height, convex height, drag height)
definition
Part of the plastic part is raised due to the improper ejection of the mold or the ejection pin and top plate acting on the surface of the plastic part.
7. Cracking (commonly known as: Explosion; other names; broken buckle, rupture)
definition
Plastic parts are partially affected by pressure, internal stress, external forces, or environmental influences on the surface or inside of the plastic parts.
8. Mottled dots (commonly known as black dots; other names: spots, gram dots)
definition
Because the raw materials are mixed with foreign objects or the local temperature is too high during the molding process, the rubber material is carbonized, which causes spots on the surface of the plastic part after molding.
9. Technical term: None (common name: mold mark; other names: mold flower, mold impression, mold mark)
definition
Scratches and bumps on the surface of the injection mold will leave traces on the production during molding.
10. Flash edge (commonly known as: Pifeng; other names: edge, hand, edge, hole, hole, etc.)
definition
During the injection molding process, the plastic overflows into the joint surface of the injection mold and the gap between the inserts, and remains on the plastic parts after cooling.
11. Poor glue running (common name: lack of glue; other names: none)
definition
Plastic parts are dissatisfied with the partial gluing and fail to meet the design requirements.
12. Uneven color (common name: mixed color; other names: none)
definition
The defect of uneven color on the surface of plastic parts.
13. Warpage (common name: deformation; other names: none)
definition
Partial or overall deformation of plastic parts caused by internal stress.
14. Layering (common name: layering; other names: peeling)
definition
Defects of separation between layers.
15. Hole plug (commonly known as: plugging hole; other names: blind hole)
definition
The hole of the plastic part is blocked by more than 50% due to the piercing or broken needle.
16. Bubbles (commonly known as bubbles; others: foaming, steam bubbles)
definition
Bubble defects formed inside or on the surface of plastic parts due to residual air or other gases.
17. The color does not match (common name: color difference; other names: color depth/light, poor gloss)
definition
The color and gloss of the plastic parts do not match the standard board.
18. Technical term: None (common name: Duojiao; other names: none)
definition
The plastic parts are partially out of glue due to the lack of the molding surface of the injection mold.
19. Technical term: none (common name: burnt; other names: burnt yellow, burnt black)
definition
Local high temperature due to poor exhaust of the injection mold will cause the plastic material to degrade and form a scorched shape; or due to the high shear rate of the rubber material in the flow process, it will degrade and form a scorched shape.
20. Technical term: none (common name: fish scale pattern; other names: none)
definition
Fish-scale patterns formed on plastic parts due to low mold temperature and slow injection speed.
21. Technical term: None (common name: glue silk; other names: offset printing)
definition
Due to the high temperature of the nozzle and the excessive back pressure, the thread-like rubber material is pulled out when the mold is ejected, and it adheres to the mold cavity. The thread is formed on the surface of the product during production.
22. Technical term: None (commonly known as: sticky mold; other names: viscose)
definition
Due to the high injection pressure and small demolding angle, the plastic parts are partially broken during ejection and stay in the injection mold.
23. Technical term: none (common name: leaking watermark; other names: none)
definition
Due to leakage in the water channel of the injection mold, water droplets are formed in the injection mold, and the water marks have not been removed, and the marks formed on the surface of the plastic part during the production of beer.
24. Technical term: none (common name: ghost; other names: none)
definition
Due to the low injection temperature, unsaturated plastic parts, product deformation, etc., the light and shadow overlap during the light transmission test.
25. Technical term: none (common name: break; other names: none)
definition
Refers to the uneven surface of the accessory after mating, resulting in a height difference.
26. Technical term: none (commonly known as: Lijiao; other names: none)
definition
Refers to the distance between the fittings after mating (not including the design process slot)
27. Technical term: None (common name: white spot; other names: white mark)
definition
White spots or white marks formed on the surface of plastic parts due to poor toner quality, ejection of the film left in the thimble when clamping, and metal in the raw material.
28. Technical term: None (common name: size is too large; other names: size is too long)
definition
Due to high injection pressure, too long holding time, inconsistent shrinkage of raw materials, etc., the size of plastic parts is larger than the required size.
29. Technical term: None (common name: size is too small; other names: size is too short)
definition
Due to low injection pressure, too short holding time, inconsistent shrinkage of raw materials, etc., the size of plastic parts is smaller than the required size.
30. Technical term: none (common name: poor assembly; other names: trial assembly tight/loose, buckle tight/loose, noisy)
definition
Due to the large and small size of the components that cooperate with each other, problems such as tightness, looseness and noise during the trial assembly are caused. Such problems are collectively referred to as poor assembly.
31. Technical term: none (common name: pillar burst; other names: none)
definition
The screw column bursts or is severely whitish during screwing.

definition
The screw cannot be tightened when the screw is tightened according to the specified torque.
33. Pulling hair (commonly known as: drag flowers; other names: none)
definition
The surface of plastic parts is dull and has no depth of traces due to slight mechanical friction.
