Sheet metal is a comprehensive cold working process for sheet metal (usually less than 6mm), including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is the same.
JM Precision has complete sheet metal processing equipment: punch, bending machine, EDM, grinder, etc., covering plate cutting, stamping, laser cutting, crimping, bending, ironing, welding and other processing processes, which can meet customers' various sheet metal processing needs.
It is a common sheet metal forming process. Punch and die group are used to punch holes in sheet metal. During machining, the sheet metal is placed between the punch and the die, and then the punch is pressed down and passes through the sheet metal, thus completing the punching process.

It is a sheet metal forming process. After the initial production of sheet metal, there are usually sharp edges with "burrs". The purpose of crimping is to smooth the sharp and rough sheet metal edges to meet the use requirements of the project.

It is another common sheet metal forming process. Manufacturers usually use brake press or similar mechanical press for metal bending. The sheet metal is placed on the die, and the punch is pressed down on the sheet metal. The huge pressure makes the sheet metal bend.

Laser cutting has become a more and more common sheet metal forming process. When the sheet metal is exposed to high power and high density laser, the heat of the laser melts or vaporizes the sheet metal in contact with it, forming a cutting process. This is a faster and more accurate cutting method, which is automatically executed by computer numerical control (CNC) laser cutting machine.

It plays an important role in construction and manufacturing industry. In the construction industry, it is used as a building and shell or roof; In the manufacturing industry, sheet metal has been widely used in electronic and electrical appliances, communication, automobile industry, medical devices and other fields. For example, sheet metal is an essential part in computer chassis, mobile phone and MP3. With the more and more extensive application of sheet metal, the design of sheet metal parts has become a very important part in the process of product development.
Mechanical engineers must master the design skills of sheet metal parts, so that the designed sheet metal can not only meet the requirements of product function and appearance, but also make the manufacturing of stamping die simple and low cost.
Sheet Metal Processing have a long list of available materials for prototypes and manufacturing parts, from hard metals like stainless steel and carbon steel, to soft metals such as aluminum, copper, brass.
Aluminum is one of the most commonly used metals in the world because of its excellent strength-to-weight ratio, low cost, and recyclability. Jinming offers multiple aluminum alloys such as 2024, 5052, 6061, 6063, 7050, 7075 and so on, as a high-quality silver metal that’s soft, lightweight and durable, it is commonly used for 5-axis CNC machining in military and aerospace applications.
Stainless steel is highly resistant to corrosion and rust, making it a popular industrial alloy used in a wide variety of industries. Stainless steel is used to manufacture handles, medical devices, lab instruments, automotive parts, weld ferrules, and more. Jinming offers multiple stainless steel such as 303,304, 316,17-4PH, 4130, 4140 and so on.
Brass is a metal alloy made of copper and zinc, brass has decent strength, electrical conductivity, and minimal tool wear. It is commonly used for a variety of parts such as gears, lock components, pipe fittings, and ornamental applications.
Bronze is an alloy comprised of copper and tin, and it offers a wide range of properties such as good wear and corrosion resistance, high ductility, hardness, thermal conductivity and strength. Bronze is often used to manufacture nuts, bolts, threaded parts, bearings, bushings, screws, and more.
Copper is a common metal offering excellent thermal and electrical conductivity, which make them natural choices for wiring, motors and other electrical applications.
Carbon Steel is a iron carbon alloy containing 0.0218% to 2.2.11% carbon. In general, the higher the carbon steel, the higher the hardness, the higher the strength, but the plasticity is low. Carbon steel is usually used in mechanical parts such as auto parts, nuts, gears. Jing Ming offers a variety of carbon steel, such as Q235, SPCC, SECC etc.
Our basic guidelines for sheet metal fabrication include important design considerations to help improve part
manufacturability, enhance cosmetic appearance, and reduce overall production time.
