1 flash (Flash) / feather (Burr)Overflow edge of the plastic material over material2. Pimple sores (Bloom)Forming a rough granular surface phenomenonA noncontinuous surface coating conming from additives in the plastic.3. Not full analog / lack of material (Short Shot / Void)Do not shoot enough material to fill the outer moldInjection of insufficient material to fill the overmold.Failure of plastic to completely fill mold cavity.4 char (Burns)Thermal decomposition, usually associated with color (Discoloration) simultaneouslyThermal decomposition, usually with discoloration.5. Shrink (Sink / Shrink mark)Surface cracking, sinking or sunken The reason is that the material does not shrink at the same time live wire or screw clampSurface discontinuity, depression or dimple caused by non-uniform materialshrinkage, or clamping of cable; depressions on a surface.http://www.prmindustry.com/Abstract...Articles section 6. Scratch (Scratches)Appearance of the surface material damage shallow grooveDamaged outer surface of jacket where material has been removed; Swallow grooves.7 cut (Cut)Appearance of the surface by a sharp object injuryDamaged outer surface of jacket by a sharp object.8. Crush (Tooling Mark)Use clamps or tools outside the wire repair the damage caused.Deformity of cable jacket resulting from clamping or tooling.9. Parting line cracking (Parting Line Split)Outside the mold material due to shrinkage, cracking or rupture resulting split outer moldThis is where the overmold material shrinks and cracks or splits, creating a tear in the overmold.Thin projection or material 90 degree to surface on a parting line.10 fusion line (Weld / Knit Line)Fusion line is the confluence of the material forming part of the forming materials of the fusion marks appear.A visible line or mark on a surface.11 Top White (Clouding)Moldings at the top position out of the phenomenon of white spots left12. Pollution (Contamination / Dirt / Blemish / Speck)Ink, dirt, flux or other foreign objects13 color / color (Color Difference / Discoloration)The original color version of the color differenceAny change from original color or unintended, inconsistent part color.14 fracture (Brittleness)Barrier, stilts or hook due to force (tension or compression) and fracture15 block (Fill in)Pin hole (coaxial holes) due to foreign body obstruction16. Indentation (Pinch off)Time of the pressure (stress) caused by the strain (outside the Depression)Any irregularly shaped, void or impression left on the overmold, caused during preparation or handling.17 deformation (Deformity / Deformation)Parts damaged or incompatible with the appearanceComponents is bent or show signs of deformation.18. Bump (Pimple)Plastic materials containing particles19. Dimple (Dimple / Pits)Plane holesSmall hollow / crater on a surface.20. Flow marks (Flow Marks)Appearance of the phenomenon of surface waves or stripesWavy or streaked appearance of a surface.21. SR tilt (Tilted Strain Relief)Cable should exit in a straight line from a connector assembly.22 Fog (Haze)Finished in the manufacturing process caused by the phenomenon of the surface of white mistCloudiness on an otherwise transparent part.23 feed point too deep (Gates)Refers to the shape, the feed point with the phenomenon of depression24. Warpage (Warpage)Phenomenon caused by the appearance of curved shape25 outstanding (Protrusion)A raised area on a surface (Blister, bump, ridge)26. Impurities (Specks)Small particles.27 bubble (Bubbles)Bubbles can be caused by not having uniform melt in the molding process.28. Blush (Harmonia)Discoloration caused by plastic flow during molding, usually found near gates.29. Gate Blush (feed point Leis)Discoloration around the gate area.30. Glossiness deviation (Glossiness)Spend less than the amount of gloss or part of an area.An area of excessive or deficient gloss.31. Dent (Gouge)Engraving can be perceived or depression (not due to shrinkage)Indentation or dent that can be felt (not a sink mark)32. Porosity holesBlow holes, pits or underfills.32. Texture flowVariation or unevenness in texture.33 surface oxidation (Oxidation)In the bare metal surface or coating surface oxidation, dirt, or the phenomenon of different colors (spray coating is acceptable).
