Stamping and sheet metal production involve many fields of manufacturing industry. In recent years, as China has become the world's manufacturing center and consumer power, stamping and sheet metal industry, as one of the basic industries of manufacturing industry, has also achieved unprecedented development. At present, China's equipment manufacturing industry is large but not strong, and the distribution is uneven. The backward heavy equipment manufacturing industry is distributed in the three northeastern provinces, while the new sheet metal equipment manufacturing industry is distributed in the coastal Yangtze River Delta and Pearl River Delta, and has just started, which is difficult to meet the domestic market demand. In the next 5-10 years, the equipment manufacturing industry will still be one of the main industries in China, especially the sheet metal industry in the manufacturing industry.


The improvement of the sheet metal processing industry is the main evaluation aspect that can best reflect the comprehensive capacity of a country's manufacturing industry. The development of the industry will reflect the improvement of the overall quality of the national development economy. China has joined the World Trade Organization for many years, but the current sheet metal processing industry is still scattered. The emerging national industry has just started, and the scale is very small. Industry integration can cope with the impact of foreign enterprises and ensure that national industries have a place in the competition. In the next 5-10 years, in addition to expanding the scale to meet domestic demand, China's sheet metal processing industry also needs to integrate production and supply and demand on the advanced Internet, so as to gain an invincible foothold and prepare for foreign development faster and better.
Analysis on the overall scale of the industry
With the rise of China's manufacturing industry, China's sheet metal and manufacturing industry has developed rapidly. According to the analysis report on market demand forecast, transformation and upgrading of sheet metal processing industry released by forward looking Industry Research Institute, as early as 2012, the whole industry had more than 30000 enterprises (workshops) and 2 million employees, with an annual production of about 42 million tons of sheet metal parts. In 2016, the sales of sheet metal processing industry was about 688.5 billion yuan. However, generally speaking, the sheet metal processing industry started late, the industry scale is generally small, and there is a lack of production and technical personnel. It is difficult to form the core competitiveness of enterprises. The market competition is becoming increasingly fierce, and it does not have the strength to compete with international multinational corporations.

At present, on the whole, the economic benefits of sheet metal processing in China are good, and the operating profits of many industrial enterprises are more than 20%. The sheet metal processing industry is mainly engaged in distribution processing for automobile, shipbuilding, precision machine tools, precision instruments, communication electronics, elevators and other industries, and most of the partners are large foreign companies (GE, Bosch, Otis). With the further deepening and lasting cooperation, they learn advanced technology, process, strict and standardized production environment Management experience in production process and other aspects, so as to gradually localize key components and key technologies, which correspondingly reduces the procurement of key components by foreign-funded enterprises from abroad and reduces the production cost of manufacturing enterprises.
At the same time, this method can also do supporting processing for domestic manufacturing enterprises, and enable them to obtain key production technologies, so as to improve the product performance of domestic manufacturing enterprises. At present, there are not many domestic high-precision sheet metal processing enterprises. Developing the sheet metal processing industry in a certain area and providing perfect supporting processing services to domestic and foreign manufacturing enterprises can not only promote the overall development of machinery manufacturing enterprises, but also drive the regional economy to achieve a new leap, and the economic benefits of enterprises are also guaranteed.
With China becoming an international processing and manufacturing center and the increasing foreign investment, the demand for metal processing capacity is increasing. Generally speaking, the electrical control box and machine shell in the metal processing industry are sheet metal parts, so the demand for sheet metal processing capacity is also increasing. In addition, as far as sheet metal processing is concerned, sheet metal processing enterprises usually need a variety of mechanical equipment to meet different process requirements. The punching accuracy of sheet metal is generally about 0.1mm, and the bending accuracy can generally reach 0.5mm. Therefore, compared with sheet metal processing, the accuracy is much lower. Therefore, the progress of industry technology has also brought high profits. For example, the stamping profit margin in sheet metal processing can generally reach about 30%, while the profit of laser cutting is more than 50%.
Industry profit level and change trendOverall, the profit level of sheet metal processing industry mainly depends on product quality and processing precision, products and value-added services, downstream user enterprises and upstream raw material prices. Therefore, in the future, with the increasing technical content of products in the industry, the impact of raw material price fluctuations on products will be gradually reduced, and the change trend of industry profit level will be better.At the same time, the future trend of profit level mainly depends on factors such as product quality and precision, product value-added services and downstream customer industries. Enterprises with strong technical strength, high-end customer resource advantages and management advantages in the industry will obtain a higher profit level in the future fierce competition.

Metal production experts use a variety of different techniques to produce customized parts, fittings, and other industrial and commercial solutions. Each technique produces a completely different product with different characteristics. Whether it is bar milling, sheet metal fabrication, or press brake forming, each has its own purpose and set of benefits.
Press Brake Forming Using a computer operated press brake forming machine, which runs at extreme pressures of approximately 350 tons, this machine literally squeezes metal into shape. Many machines can work with up to a 3/8" thick material that is upwards of twelve feet in length. Press brake forming also works with a variety of different metals including brass, stainless steel, aluminum, and carbon steel. So what is it used for? If you need a metal housing for a particular part, brackets for machines and equipment, metal framing, and even decorative touches, this method will likely be the one used. This is an ideal solution for anyone needing replacement parts, large numbers of brackets, and fastening solutions as well as prototypes for almost any type of machinery.
Bar Milling Bar milling is reforming an existing bar into a particular shape, form, and length to make it fit various jobs and specifications similar to running a router or shaper down a narrow length of wood. This could be by taking traditional round or square bars and making them into hexagonal or angled bars, adding grooves or other features down the entire length. It can also be made from various materials including brass and stainless steel. To create each shape, the specialist puts together a series of cutters that could be bevels, round overs, slots, and much more. Finally, it is milled down to a smooth surface and made into the proper dimensions.
Sheet Metal Fabrication Sheet metal fabrication is ideal for detailing and precision cutting. With this method, specialists can use laser cutting, punching, press brake forming, shearing, and welding to create virtually anything from this super-thin and flexible metal product. It is used for everything from cultivator shovels and hopper bottoms for the agriculture industry to conveyor parts, guards, frames, decorative metal forms, and many other items for a variety of other industries.
