1. Start with the surface treatment of the product: the product made from the good plate has a smooth surface and the surface treatment is smooth. The products made from poor plates are pitted, even if it is done with several layers of surface treatment, because the surface treatment will not fill the surface defects of the product. Some will also have problems such as small bubbles or yellowing. These are the performances of the defective products.

2. Starting from the edge and inside of the product: good products are produced through burrs, so that the products will not be scratched or ugly; even the products that have been used for a long time will be burrs, so they must be processed. The poor product is produced and assembled directly without surface treatment, so that a part of the cost can be saved, and it will be scratched or difficult to open when used, which is called cutting corners.

3. Starting from the thickness of the product material: People often see that the product is thick and used for a long time. The poor product is thin and cheap, and it will take a long time to break. The same is true for the same reasoning. The good product material is thick, the force is strong, the number of uses is long, and the service life is long. The poor product material is weak under the force, so that the deformation is easy to damage, and the number of uses is small and short.

4. Starting from the assembly technology of each product of the product: the product is good or bad, the service life is long and short, and the assembly technology has a great relationship with the assembled parts. A good product is assembled and the details of each activity are quite flexible. The rivets and springs are made according to the size standard of the product. Poor products are assembled too tightly, or too loose, too much clearance, up and down, rivets and springs are non-standard, which will reduce the quality and life of the lock.
