Bolts High-grade, High-precision, High-strength Snail

Over the years, the Chinese bolts in the continuous double-digit growth, the 2012 bolt industry negative growth, down 1.5% or so, mainly due to lack of market demand, especially in the international anti-dumping of the bolt, the export sales fell situation.

Bolt market competition, to brand management

Nearly 10 years, the Chinese bolts to the world's attention to the pace of development, so that developed countries are surprised at the same time, but also let them find a new large market, multinational companies filed into the fish.

When the domestic bolts enterprises suddenly feel that in the market to survive so difficult, a strong competitor has been blossom everywhere.

China's current bolt market, some small and medium-sized bolt enterprises to create a large number of ordinary standard parts, and not really bring the core competitiveness of enterprises, but subject to raw materials, labor costs and other conditions change. From 4.8 to 6.8 low-intensity, or 8.8 to 12.9 high-strength bolts, the current level of China's bolt production technology will be close to the world's advanced level, mainly for ordinary standard parts and low, medium grade special, shaped bolt, Big cheap.

Summary of low-grade products flooded the dominant market, high-grade, high-precision, high-strength bolts are still a small part of imports, product import price and export price ratio of about 6 times the gap.

It can be seen that China's bolt industry is still the development of the industry, "big but not strong", "fat and not strong", and the United States, Japan, South Korea and Taiwan, China's large gap between the lack of technical services to solve the mechanical tight Solid solution, to achieve the product, design, manufacture and management of the digital, product and manufacturing process of green.

It is understood that the development of Chinese bolts by resources and the environment is growing pressure to ease the constraints of resources is an important way to develop green manufacturing.

The development of bolts, the next period of time will also continue to move towards the direction of the brand to actively promote the development of bolts project in all directions.

In the product, the high-end products will accelerate the localization of quality research and development, from design, manufacture, packaging, transportation, use to the whole process of retirement, should consider the least waste, the lowest emissions, the highest utilization of resources and environmental impact The smallest, so that the enterprise efficiency and social benefits coordinated and optimized.

Bolt for special purposes, T-slot bolts, machine fixtures with the most, the shape of special, both sides of the head to cut off. Anchor bolts for machine and ground connections are fixed, there are many shapes. U-bolts, as previously described. and many more. There are special studs for welding, one with a thread, which can be welded to the part and the other side is directly screwed.

The grade of bolts, the grade of bolts for steel structure connection, such as 3.6,4.6,4.8,5.6,6.8,8.8,9.8,10.9,12.9 and so on, among which 8.8 and above are low carbon alloy steel or medium carbon Steel and heat treatment (quenching, tempering), commonly known as high-strength bolts, the rest known as ordinary bolts.
