Definition and judgment of color difference in vacuum plating:

Color difference is simply the difference in color. The cases of color difference include: 1. The difference between the finished product and the standard color plate; 2. The difference between the same part and the same batch of finished products; 3. The same part in different batches Differences between finished products; 4. Differences between different parts of the same batch of finished products; the judgment of color difference is usually no more than two ways: 1. Manual judgment by visual inspection and comparison of color plates; 2. The color difference analyzer is used for computer analysis and comparison; because the color difference analyzer has certain limitations, the current industry widely used is a manual visual comparison and judgment method for color difference inspection.

Choice of vacuum plating polishing wheel size

For example, the selection of the size of the polishing wheel: the power of the motor determines the size of the polishing wheel, and the shaft of the motor must be matched with the polishing wheel. Place the buffing wheel in the center of the shaft and tighten it with a wrench. The best polishing effect can be obtained only when the linear speed of the surface of the polishing wheel is uniform, so if a large polishing wheel is used with a smaller motor, the linear speed will drop a lot during polishing, and the polishing effect will be affected.

Terms commonly used in vacuum electroplating mechanical polishing are:

1 Abrasive: The particles in the polishing wax that play the role of cutting and leveling.

2. Grease: stearic acid, fatty acid, paraffin, etc., which play a role in lubricating and cooling in polishing wax.

3 Cutting force: The ability of polishing wax to grind and level the polished workpiece.
