Seven Common Metal Processes
1.Forging
Principle: Forging is a process of changing the shape of metal through pressure processing. During the forging process, the metal billet is placed in a mold, and then pressure is applied through the forging equipment to deform the metal and reach the desired shape.
Features: Forging can obtain high-strength and high-toughness metal products. The forging process is conducive to improving the performance of the product. Forging is suitable for various metal materials, especially high-strength steel and non-ferrous metals.
Process limitations: The investment cost of forging equipment is high, and the production scale is limited. The deformation of the metal during the forging process is large, and it is easy to produce problems such as cracks and uneven deformation.
Principle: Die casting is a high-speed, high-Pressure Casting process.
Features: Die casting can produce metal products with high precision and good surface quality. Die casting has high production efficiency and low energy consumption. It is suitable for non-ferrous metals such as zinc, aluminum, copper and their alloys.
Process limitations: The Die Casting Process has high requirements for the mold, and the cost of replacing the mold is high. Defects such as pores and shrinkage holes are prone to occur inside the die casting.
3.Stamping
Principle: Stamping is to use a punch and a mold to press the metal sheet to achieve the required shape and size.
Features: Stamping can produce metal products with high precision and good surface quality. Stamping has high production efficiency and low energy consumption. It is suitable for various metal sheets, especially cold-rolled steel sheets.
Process limitations: Burrs, tears and other defects are prone to occur during the stamping process.
4.Bending
Principle: Bending is to bend the metal sheet on the bending machine to achieve the desired shape.
Features: Bending can produce various complex metal components. Bending has high production efficiency and low equipment investment cost. It is suitable for various metal sheets.
Process limitations: Defects such as creases and burrs are prone to occur during the bending process. The size and angle accuracy of the bent parts are limited.
5.Turning
Principle: Use lathes and tools to cut metal to achieve the desired shape and size.
Features: The volume of metal is reduced during processing, and the surface quality is high.
Process limitations: Applicable to metal materials with good plasticity, such as iron, steel, etc. Not applicable to hard and brittle metal materials.
6.Milling
Principle: Use milling machines and tools to cut metal to achieve the desired shape and size.
Features: The volume of metal is reduced during processing, and the surface quality is high.
Process limitations: Applicable to metal materials with good plasticity, such as iron, steel, etc. Not applicable to hard and brittle metal materials.
7.Grinding
Principle: Use grinders and grinding wheels to grind metal to achieve the desired shape and size.
Features: The volume of metal is reduced during processing, and the surface quality is extremely high.
Process limitations: Applicable to metal materials with good plasticity, such as iron, steel, etc. Not applicable to hard and brittle metal materials.
