How many small and medium sized hardware industries have evolved after a slight development. They chose to diversify their businesses. As a result, many companies have lost their lives, and some companies have since then slumped or even closed down. After a large number of companies have weathered the market waves, they learn lessons, promptly close their hands, and return to their jobs. Development path. These lessons are very profound and they can achieve several advantages: First, technological advantages, and SMEs take the path of specialization. One of the leading technologies. The second is the efficiency advantage, increase the efficiency of equipment use, and prevent duplicate construction. The third is management advantages, establishing an efficient management system for a relatively simple production and operation system. As a result, SMEs concentrated their limited resources and specialized in their own professional fields and specialized products to win in the market competition.

The human, financial, and material resources possessed by the company are very limited. In the fierce market competition, it is impossible to win with scale. In particular, it cannot directly confront the large-scale enterprises with the same products. The advantage of a small manufacturing company lies in its professionalism and dedication to win. As Shanghai Aodaco Co., Ltd., it specifically selects high-end fasteners as its product to settle down, and takes the path of professional development.

It is impossible for the small and medium-sized hardware industry to fully counterattack the flagship product and its upstream and downstream products. The reason is very simple. Competing with large companies, it is not possible to obtain comprehensive technological advantages in the main product areas and upstream and downstream areas. It is impossible to establish a comprehensive and complete management system in all these areas. It is impossible to establish a large sales network and sales service network because SMEs have very limited resources. What a small and medium-sized enterprise can do is also necessary to do so only in the manufacture of a product, to do it professionally, to make it deep, and to do fine, so that this product is technically superior to the large-scale enterprise in the same industry, and is more sophisticated and superior. More advanced technology, finer technology, better performance products.

This is the advantage of small and medium-sized enterprises competing with large companies. Japan's small manufacturing companies have done very well in this area. A model of learning. Many Japanese small businesses have for decades produced only one product, specializing in one technology and honing a process. Focusing on one area for a long time makes these companies the best in their respective fields. This dedication to a process technology is known as a kind of professional spirit and constitutes a refinement of the prominent features of the Japanese manufacturing industry.
