Hinge manufacturers teach you how to judge quality

Starting from the surface treatment of the product: the product made from the good plate has a smooth surface and the plating is smooth. The products made from poor plates are pitted, even if several layers are plated, because plating does 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.

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 produce burrs, so they must be processed; Poor products are produced and assembled directly without surface treatment. This saves a part of the cost, and it will be scratched or difficult to open when used. This is called cutting corners.

Starting from the thickness of the product material: people often see that the good product material 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 buckles. The good product materials are thick, the force is strong, the number of uses is long, and the life is long. The poor product material is weak under the force of the material, so that the deformation is easy to damage, the number of uses is small, and the life is short.

Starting from the assembly technology of each product: the product is good or bad, the life is long and short, and the assembly technology has a lot to do 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 either too tightly packed or too loose, the gaps are too large to shake up and down, and the rivets and springs are non-standard, which can degrade the quality and life of the product.

Starting from the intrinsic quality of the product: a good product does not require a fancy external packaging. A good non-durable packaging is a common means used by many manufacturers to deceive consumers. It is a really good product to stand the test of time.
