The overall development of the lock industry in China

The overall development of the lock industry in China

First, the basic situation of the national lock industry, lock products are closely related to people's lives, to protect the social stability and prosperity of the hardware products, but also China's hardware products large foreign exchange earnings. China is the world's largest producer of locks. At present, China's lock manufacturing enterprises have reached 1800, and annual export earnings have increased from 0.6 billion US dollars to 500 million US dollars, and exported to more than 160 countries and regions; in the traditional padlocks, door locks, drawers, negative Based on the foundation of the emerging industries and construction industry, spherical door locks, car locks, motorcycle locks, electronic locks, magnetic card locks, and IC long locks have come into being, developed rapidly, and gradually formed in Guangdong, Shandong and Zhejiang. , Su, Shanghai five lock sector. With the shifting of the lock industry from developed countries to developing countries such as China, the structure of China's lock industry has also begun to change, shifting from developed large and medium-sized cities to small and medium-sized cities and townships, and is quite concentrated. The production of the five major bases for lock production can account for more than 92% of the total lock production in the country. This is in line with the development law of the lock industry. As a result, we also pointed out the way out for our old lock base: that is, we should imitate the experience of other countries, carry out strategic shifts, give full play to the advantages of the old factory's brand name and technology, and re-open high-tech, high-value-added, high-grade products. Heaven and earth, to remake the new leader. From 2003 to 2009, there were many new companies in the lock industry. The production volume was increasing and the sales volume was also increasing. The entire lock market was booming. But at the same time, the competition is fierce, and the price war is also very cruel. The collective benefit of the whole industry has declined. From the top five bases, Guangdong and Zhejiang have better returns, and the poorer ones are in Shanghai. Some big companies are losing or losing money. From the point of view of production volume, the lock products are broadly divided into: the production of hot hand mild ball locks is mainly concentrated in Guangdong and Zhejiang; the production of padlocks is mainly concentrated in Zhejiang and Shandong; the production of mortice locks is mainly concentrated in Jiangsu and Shanghai; ordinary doors Lock production is mainly concentrated in Shandong and Guangdong. From the perspective of grades, the high-end locks are mainly spherical. At present, spherical door locks can be roughly divided into three grades from the price point, namely high-grade, mid-range, and low-grade. Among them, the mid-range ball-type door locks, because the technology is not too complicated, the equipment investment is not much, so there are many enterprises that produce this product, the grades and types of the grade products are numerous, and the sales volume in the country ranks first. Another best-selling product is the anti-theft lock. With the rise of security doors, matching locks are also selling hot.

Second, the high-end locks still need the industry to work together and the development of new products in China's lock industry in recent years, both in terms of product technology, or in terms of product quality, have been improved. According to our investigation of new products developed in the lock industry in the last five years, many companies have developed new products, such as: Shanghai used lock factories to develop Santana series locks, IC card electronic door locks, and steel door and window locks; Shandong Jinfeng Group Company has developed computer door locks, double-leaf door locks and valve locks; Hangzhou Locks Industrial Co., Ltd. has developed a building intercom system; Yale-Gugli Security Products (Guangdong) Co., Ltd. has developed a spherical function door lock including a balcony. / Garden lock, entrance lock, classroom lock, connectivity lock, emergency exit lock, storage lock, hotel president lock, etc. Although the situation is excellent, there are few high-end products. China's high-end hotels, hotels and other locks or rely on imports, the domestic high-end locks market is still controlled by foreign locks. The accumulation of the lock-making industry has reached a process that should undergo qualitative change. It should be developed for middle-to-high-end, high-tech locks, and some companies should break away from low-level price wars and launch a new round of technological competition.

Thirdly, regulating the market of locks is bound to create a good consumer environment for the lock market, further increase the special rectification of the lock market, and severely crack down on the circulation of counterfeit and inferior products of locks to the market. The market sampling results in recent years show that we The relatively poor product quality is mainly due to high open rates. At the same time, some locks also have problems in assembly. Except that some of the more formal manufacturers still use the key tooth, many manufacturers use lock cores and marbles, which causes the lock core to deform and directly affect the open rate of locks. The above reflects two aspects: On the one hand, it is subjective. This is in the fierce market competition. In the cruel price competition, some companies lose sight of profit, ignore the interests of consumers, cut corners, shoddy, and shoddy. In order to seek their own interests, this aspect should arouse the attention of relevant departments; on the other hand, it is objective, and this is a technical problem such as a process problem, an assembly problem, etc. Enterprises in this area should step up, improve, and improve. In order to better safeguard the legitimate rights and interests of well-known lock companies and consumers, the China Hardware Products Association commissioned the Shanghai Testing Center to fully focus on the current situation of locked locks and to speed up efforts to conduct unannounced visits to the entire lock market, investigations, and random checks of locks. It is beneficial to the overall development of the lock industry in China and also the blue sky of the lock market.

Electroplated Saw Blade

Diamond Saw Blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone materials, and ceramics. The diamond saw blade is mainly composed of two parts; the base body and the cutter head. The base body is the main support part of the bonded cutter head.
The cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the matrix will not. The reason why the cutter head can cut is because it contains diamond, and diamond is the most important part. A hard substance that rubs and cuts the workpiece in the cutter head. The diamond particles are wrapped by metal inside the cutter head.
Electroplating (brazing) diamond saw blade: the blade powder is attached to the substrate by electroplating.
