Although there has been some economic downturn, the global demand for bolts has been on the rise.

More and more bolt products produced by new materials are concerned and applied by some high-tech enterprises.

Under the premise of lightweight, standardization and high quality quantification of bolt materials, the traditional bolt production technology has faced challenges.

The bolt production of existing materials does not have any problems in the manufacturing process. No matter it is foreign or domestic, there is not much difference in the grasp of the bolt production technology.

Because we for such products as bolts, the quality of the surface treatment plays a decisive factor.

But the surface treatment of this piece, foreign products than domestic there is a leading side, actually, these surface galvanized or nickel plating technology is from the developed countries.

The most common surface treatment for bolts

The most common finishes for bolts are zinc and nickel plating. Only from the appearance of the finish, there is no difference with foreign products, but a long time, you will find that there is rust.

How to control the quality of bolt surface treatment has become the most important problem in China.

In the case that the technical conditions are not so mature, we can only carry out necessary tests on galvanized bolts and nickel-plated bolts.

Although it will increase the cost, but for the sake of safety, we can only do more work in this link.

For some high-end bolt application enterprises, such as automobile companies, they will be more stringent inspection of the supplier’s quality system certification.

Complete production license and ISO certification are required for filing, both for surface treatment and for manufacturing.

Therefore, the high quality surface treatment of bolts is a rigid requirement of the entire industry. In some key occasions, even if a bolt is rusty, the consequences caused by it are unthinkable.

This is why the imported bolts are expensive, in the final analysis, because the quality is good, the enterprise with rest assured ah.

With the further enhancement of environmental inspection, although caused a period of bolt price surge.

But the tide receded, also brought some benefits, environmental inspection at the same time, but also let some electroplating companies in the shutdown time will be the original painting of the equipment to update.

It can be said that since the environmental inspection, until today, the existing bolt galvanizing technology has not been a level with before.
