TOOLS & HARDWARE refers to a general term for various metal devices manufactured from iron, steel, aluminum and other metals through forging, calendering, cutting and other physical processing.

Hardware tools, according to the use of the product to divide, can be divided into tool hardware, building hardware, daily hardware, lock abrasives, kitchen and bathroom hardware, home hardware and hardware parts and other categories.

Hardware tools, including all kinds of manual, electric, pneumatic, cutting tools, auto tools, agricultural tools, lifting tools, measuring tools, tool machinery, cutting tools, jigs, cutting tools, tools, grinding wheels, drills, polishing machines, tool accessories, measuring tools and cutting tools, paint tools, abrasives and so on.

In the global sales of power tools, the vast majority of them are produced and exported from China, China has become the world's major power tools supplier.

The relationship between the energy of impact and the impact speed can be analyzed from the following formula W=1/2mv*v W -- the energy of impact on the workpiece; m -- the mass of the hammer itself; v - Give the hammer the speed at which the hammer strikes.

When the hammer mass is doubled, the energy is doubled, and when the speed is doubled, the energy is increased by 4 times. Therefore, in order to be safe, when using a hammer, it is necessary to correctly choose the hammer and grasp the speed when hitting.

When using a hand hammer, pay attention to the connection between the hammer head and the hammer handle must be firm, a little loose should be immediately wedged to tighten or replace the hammer handle, the length of the hammer handle must be moderate.

In 2013, in the hardware market, developed countries in Europe and the United States, due to the rapid development of production technology and the increase in labor prices, the universal products are transferred to the production of developing countries, and they only produce high value-added products.

China has a strong market potential, so it is more favorable for its development as a hardware processing export country. China's hardware market, mainly distributed in Zhejiang, Jiangsu, Shanghai, Guangdong and Shandong and other places, of which Zhejiang and Guangdong are the most prominent.
