The development of domestic mold industry will enter a new stage

China's mold industry has broad prospects, but because China's mold technology still has a certain gap compared with the current international level, the backwardness of mold technology has caused the independent development of many industries in the manufacturing industry to be greatly restricted. Some high-tech molds are still Dependence on imports, coupled with foreign advanced enterprises in recent years, pay more attention to the protection of technology, which has caused certain difficulties for China's mold enterprises to introduce technology. Senior experts in the industry said that it is imperative for the industry to improve the manufacturing level of China's mold industry as soon as possible. With the continuous development of the national economy and industrial product technology, the demand for molds in various industries has become larger and larger, and the technical requirements are getting higher and higher. The focus is on developing high-tech molds and continuously improving the standardization level of molds in China. At one time, it became the focus of the 12th Five-Year Development. Especially for the precision mold industry that relies on the mold of high-tech products, such as computer casings, connectors and precision plastic molds and precision stamping dies in the manufacture of many components, etc., are indispensable for the production of electronic products. Tool equipment. With the formation of global market integration, the competition in the manufacturing industry is becoming more and more fierce. The development speed of products has increasingly become the main contradiction in the development of the industry. In addition, the mold industry has gradually undergone structural adjustment and upgrading, and has special dependence on specific users. There are many varieties of products, the size is very different, the requirements are different, so the mold companies have begun to turn to the refined, specialized and strong routes. In order to meet the ever-changing needs of users, more companies are beginning to accept orders for small batches or even single-piece production. How to increase the development speed without increasing product costs has become the first problem that every enterprise needs to solve. It can be seen that in the future, the demand for the domestic mold industry is still very large, and its development speed will maintain a high-speed growth trend.

Definition of Sheet Metal Fabrication
Sheet Metal fabrication is the creation of useful metallic parts and structures by the application of multiple fabrication processes. Sheet metal fabrication is basically a broad term that involves various complex processes like cutting, forming, bending, welding, machining, and assembling. The instructions include below: materials, processes, and tools required for sheet metal fabrication.
Types of Sheet Metal Fabrication Materials
The choice of metal depends on the final use of the fabricated parts.
Common fabrication processes:
• Carbon Steel
• Stainless Steel
• Aluminum
• Bronze
• Copper
• Brass
• Aluminized steel

• Galvanized steel

Sheet metal fabrication: Forming or Deformation
Bending: Sheet metal bending is one of the most popular deformation processes. A machine known as a Press brake is used to bend sheet metals into V, U, or other complex shapes. With an increase in gauge thicknesses of sheet metals the force required to bend increases.
Stamping: In the stamping process, a hydraulic or mechanical stamping press equipped with a tool and die is used to perform specific tasks like curling, drawing, embossing, flanging, etc
Hemming: Hemming is a process by which the edges of sheet metal are folded over itself or another piece of sheet metal to create a rounded edge. In the sheet metal fabrication process, two types of hemming processes are widely involved. They are roll hemming and conventional die hemming. Conventional hemming is used for mass production. A hemming roller is used for roll hemming.
Spinning: Spinning is a metal fabrication process where a lathe machine is used to rotate the sheet metal against a tool to produce conical or cylindrical shapes.

Advantages and Disadvantages of Sheet Metal Fabrication
As sheet metal fabrication covers a wide area of techniques and methods, the advantages and limitations will vary depending on the process used during fabrication.
Benefits:
i. Sheet metal fabrication is fast and can produce high-quality components.
i. A large number of processes are available with wide range of materials
ii. High strength to weight ratio for sheet metal fabricated parts.
Disadvantage:
i. Each fabrication process has their own limitations.
ii. High initial cost for set up of equipment and tools.
iii. Requirement of skilled labors for each process.
