Advanced bolts are the basis of high-end machinery manufacturing, and their role can be described as "a two-pronged effort." The surface bolts only account for a few percent of the machinery industry. In essence, the added value it brings to key components and equipment is much higher. Over the years, after consecutive double-digit growth in China's bolts, the bolt industry experienced a negative growth in 2012, a year-on-year decrease of about 1.5%, mainly due to insufficient market demand, especially after bolts suffered international anti-dumping, export sales decreased. situation.

The bolt market is fiercely competitive and goes toward brand management. In the past 10 years, China's bolts have drawn world attention, which has surprised the developed countries and allowed them to discover a new type of big market. Multinational companies have come alive. When domestic bolt companies suddenly felt that the market survived so hard, powerful competitors have blossomed. In today's bolt market in China, some small and medium-sized bolt companies have manufactured large quantities of common standard parts. They have not really brought core competitiveness to enterprises but are subject to changes in the conditions of raw materials and labor costs. From 4.8 to 6.8 low-strength, or 8.8 to 12.9 high-strength bolts, China's bolt production technology level will be basically close to the world's advanced level, mainly for ordinary standard parts and low, mid-level special, Non-Standard Bolts, a large quantity Cheap.

Summarized as the low-grade products flooded with the dominant market, high-grade, high-precision, high-strength bolts still need a small part of the import, the ratio of product import price and bid ratio of about 6 times more. It can be seen that China’s bolt industry is still a developing industry, “big but not strong”, “fat but not strong”, and has a large gap with the United States, Japan, South Korea, and China’s Taiwan region, and lacks technical services to solve mechanical problems. Solid solutions to achieve the digitization of products, design, manufacturing and management, and the greening of products and manufacturing processes. It is understood that the development of China's bolts is getting more and more pressure on resources and the environment. An important way to ease resource constraints is to develop green manufacturing. The development of bolts will continue to move forward in the direction of brand management for a certain period of time to promote the development of bolt projects in all directions.
