Blemishes on the cast surface created due to soft part ejection impact onto other parts, machinery, floor, etc.∙Surface Porosity: Holes in the casting due to 1gases trapped in the mold, 2reaction between molten metal and moisture in the sand, or 3imperfect fusion of chaplets with molten metal, ∙Hot Tear: Irregular shaped fracture in a casting resulting from stresses set up by steep thermal gradients within the casting during solidification.∙Inclusions: Particles of slag, refractory materials, sand, or deoxidation products trapped in the casting during solidification.Molded Plastic Defects∙Blush:Discoloration or change in gloss, usually at gate areas or where wall thickness changes.∙Bubbles:Transparent parts or void pockets (may appear as a blister or bulge on colored parts).∙Burns:Brown marks, spots or streaks (usually associated with poor venting of gasses during molding).∙Cold Slug: Visible inhomogeneous melt from the first material to enter the mold during

white marks that are visible due to stress exerted on the part.∙Delamination:Separation of the layers of plastic.∙Discoloration: Inconsistent color or any deviation from the color standard.∙Drag Marks:Scratches from the plastic scraping against the mold during part ejection.∙Flow Marks:Directionally off-tone wavy or streaked appearance of a surface.∙Flash:Excessive plastic along the parting line or mating surface of the mold.∙Gas Marks: Burn marks or dark discolored streaks usually caused by inadequate venting of the gasses trapped in the mold during the injection phase.∙Gouge:Surface imperfection due to abrasion, nicking or poor trimming.∙Grease:Machine lubrication on the part.∙Haze:Cloudiness of a transparent part.∙Marbling:Colored streaks due to incomplete mixing of color.∙Nicks:Surface scratches or indentations due to mis-handling of part.∙Particles:Small discolored spots or matter embedded in material.∙Pin Push:Distortion or protrusion caused by ejector pin pushing into part.∙Pitting: Crater-like imperfections in the material.∙Porosity:Holes or voids in the material.∙Protrusion:Raised area on a surface, such as a blister or bump.∙Pulling:Part distortion caused from plastic sticking in the mold.∙Scratch:Surface imperfection due to mis-handling.∙Shine:Glossy or shiny areas on textured surfaces.∙Shorts/short shots:Missing material due to incomplete filling of the mold.∙Sink:Surface depression that occurs during cooling phase of the part.∙Specks:Small discolored spots or matter embedded in the material.∙Splay:Off-colored streaking (often silver-like) caused by moisture in the material or thermal degradation of the resin during processing.∙Weld Lines:Appears as a line where two or more fronts of molten plastic converge (also called knit lines).∙Witness Lines: A visible line formed by the junction of two pieces of steel in the mold.Painted Part Defects∙Orange Peel: Film that has the physical appearance of an orange peel.∙Fat Edge: Visibly thicker paint build near edges or through-holes.∙Dry Spray: A rough, textured surface often confined to a small area.∙Sag or Run: Tiers, drips, or curtains of paint on vertical or inclined areas.∙Color Mismatch: Finished panels do not match color standard.∙Fisheye: Small, crater-like opening in the finish after it has been applied.∙Dirt: Small bumps deposited in, on, or under the paint film.∙Peeling: Any paint layer that peels off substrate or underlying coating layers.∙Solvent Trap or Popping: A "goose pimple" or volcano appearance in paint film which, on close examination, frequently has small holes in the center of the bumps.∙Mottling: Spotty, non-uniform, blotchy appearance of metallic paint.Labels, Printed Defects∙Fish Eye: Undesirable circular flaw in the printed image usually caused by bubbling of the ink.∙Ghost Image: A second image that is slightly visible behind the desired print.∙Moire: An undesirable optical effect that can occur when printing halftones or four color process.∙Mottle: A spotty or uneven printed surface with is most apparent in solid areas.∙Pin Hole: A defect or void that appears in the desired print.∙Spider Webbing: Small strings of ink that appear around the edge of print. These are usually caused by static electricity or surface tension problems.∙Streaks: Elongated defects in a printed image.IMD Film Defects∙Washout:The displacement of ink from the film by plastic flow.∙Contaminants:The entrapment of visible particles, etc. between the film and plastic or embedded in the film surface.∙Wrinkle:Wrinkle, fold, or crease in the film from inadequate film positioning, injection velocity, or loose film which most often occurs near corners or edges where part radii are extreme.∙Film Flash:Film remnants that extend beyond the part or in through-holes.∙Breakage:Breaks or gaps in the film where underlying substrate is visible.∙Film Tear:Breaks or gaps where underlying substrate breaks through the ink / film and is visible on surface of the part.∙Mis-registration:Improper alignment of film pattern, icon, etc. with the part that is out of specified location tolerance.∙Scratch: A mark in the surface that is characterized by its long length relative to its depth and width.∙Poor Opacity/Coverage:Inadequate hiding power of the film to maintain proper color or adequate contrast.∙Inadequate adhesion: Any peeling, cracking or delamination from substrate or underlying layers.∙Dents:Any indentation into the part that is visible on the decorated surface.∙Color Contamination or Discoloration:Any unintentional visible variation in color.∙Missing Artwork:Incomplete image or icon.Heat Transfer Film Defects∙Contaminants:The entrapment of visible particles, etc. between the film and plastic or embedded in the film surface.∙Wrinkle:Wrinkle, fold, or crease in the film from inadequate film positioning, improper application, or loose film.∙Film Flash:Film remnants that extend beyond intended decorated surface or in through-holes.∙Breakage:Breaks or gaps in the film where underlying substrate is visible.∙Film Tear:Breaks or gaps where underlying substrate breaks through the ink / film and is visible on surface of the part.∙Mis-registration:Improper alignment of film pattern, icon, etc. with the part that is out of specified location tolerance.∙Scratch: A mark in the surface that is characterized by its long length relative to its depth and width.∙Poor Opacity/Coverage:Inadequate hiding power of the film to maintain proper color or adequate contrast.∙Inadequate adhesion: Any peeling, cracking or delamination from substrate or underlying layers.∙Dents:Any indentation into the part that is visible on the decorated surface.∙Color Contamination or Discoloration:Any unintentional visible variation in color.∙Missing Artwork:Incomplete image or icon.。
