有空多看看，這樣對於問題點的描述會變專業點。Sheet Metal Defects Abrasion: A scuffed or rubbed surface imperfection Arcing Marks: Marks in the part caused by the part coming into contact with the plating tank. Brush Finish: Finish produced by texturing with brushes or other abradants such as glass/nylon rollers. Burr: Ragged or sharp protrusions on edges or holes Dent: A depression or hollow made by impact or pressure. Pitting: Depressions in the material surface which result from the removal of roll inclusions and/or oxidization. Scratch: A mark in the surface that is characterized by its long length relative to its depth and width. Slug: A small piece of material produced during stamping when piercing a hole. Slug Marks: Dents caused when slugs are trapped between the mating die surfaces and the sheet metal. Water Spots: Discolorations on sheet metal caused by impurities in the wash. Wipe marks: Abrasions caused from the forming tooling wiping the material during a forming or bending operation. White Rust: Powdery substance resulting from zinc coating oxidization.Die Cast Defects Cold Shut: A casting defect caused by imperfect fusing of molten metal coming together from opposite directions in a mold. Rubs: 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 injection. Contamination: Discoloration from foreign material or foreign material embedded in the surface. Cracking: Splitting or fissures causing separation of the material. Crazing: Tiny cracks or 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: Brea
