4、d surface and the line of sight within 45 degrees of rotation, in order to make the parts to test in all possible illumination conditions, inspectors should rotate in all directions from the product so that all defects are visible. 3.5 Inspection environment In order to reduce inspector to determine

5、 the color error we need to create an environment that is neutral color, so the components and assemblies should be in front of a gray background.3.6 Inspection instrument Inspectors need to use point gauge to determine the flaws of appearance, the picture of point gauge see chart:3.7 Defect Definit

6、ion Serious defect: Product defect jeopardize user or producers life & security Major defect: Defect reduces product function or used effect, can not meet expected objective. Minor Defect: Defect doesnt influence product function or used effect, just a blemish.3.8 Sampling standard The sampling stan

11、ss: Use the signed standard sample or the color limit sample as the standardSpot defect: Take the largest area as the size of the spot defectColor mottle: There is a spot, which has color difference from the other area of product.Shrinkage: It is hard to maintain the high molding pressure to injecti

12、on molding the uneven product thickness, which will cause the sink mark on the thicker cross section area.Weld line: During the injection molding process, the plastic flow encounters many tool structures and plastic flow cannot melt and integrate well, which leaves an obvious line on the surface of

13、plastic parts.Cracking: The internal stress or the damage leads to the cracking on plastic parts surface.Oil Stain: There is oil mark left on plastic part surface.Warp & deformation: The stress or the uneven force during molding process will cause the warp and Deformation of plastic part.Flash: Due

14、to injection molding technique or the tool, it may cause the flash on the parting area.Scratch mark: The friction or scratch leads to spot, line or flake damage.Bubble: If the plastic pellet has been fully dried before molding, the water in the high-temperature Plastic will vaporize and leas to bubb

15、le on the plastic part.Streak: There are growth-ring lines around the gate.Fat edge: The paint is uneven and stacks up on certain area of painted parts due to the improper leveling.Orange peel: There is orange peel-like winkle on the painted part surface. Particle: There are tiny particles on the pa

16、inting part surface.Fabric: There are some tiny furs on the painting layer.Color difference: The painting color is different from the standard color board or golden sample.Gloss difference: The gloss of painting layer is beyond gloss difference of the standard sample.Roughness: The painting surface

17、is uneven and rough.Stain: There is blemish or blot on the painting surface.5. Surface of the product GradeProduct has four levels: Front、Back、Flank、Inside.Front: The front of visual area, include the display area of LCD, the front camera area、Sensation、touch key Back: The back of visual area, inclu
