What Is Forging ?
Forging is a manufacturing process that involves shaping metal with localized compressive forces. The blows are delivered with a hammer or a die. Forging is frequently classified according to the temperature at which it is performed: cold forging, warm forging, or hot forging.
Forging Method
Small forging jobs can be done by striking it with a hammer, but heavy forging jobs can only be done by machines. There are three methods for forging.
1. Hand forging
2. Drop forging
3. Power forging or machines forging
1. Hand Forging
Hand forging or smithing is the process of shaping a job by striking it with a hammer. Hand forging is employed only to shape a small number of light forgings chiefly in repair shops. Hand forging has recent years, been superseded by power forging.
2. Drop Forging
Drop forging is the process of shaping metal and increasing its strength. In most forging, an upper die is forced against a heated workpiece positioned on a stationary lower die. If the upper die or hammer is dropped, the process is known as drop forging.
3. Power Forging
Power Forging is a manufacturing process that results in the shaping of metal by using calculated force. Forging is executed with a power hammer or a die during the shaping process to produce the intended design of the forged metal object.
Advantages Of Forging Operations
? The metal’s tensile strength is reduced, and it gains the property of plasticity, allowing us to shape the metal to our specifications.
? Drawing out, jumping, and bending operations are made simple by the properties of plasticity and malleability.
? A forged job is simple to finish because its shape is nearly complete and it takes less time.
? Other machine activities can be easily carried out on the job after forging on hand metal.
? There is little metal waste.
? Hot forging improves the structure of metal.
? On the metal, there is little room for stresses and cracks.
Disadvantages Of Forging Operations
? When metal is heated, oxidation occurs, which harms the metal.
? Brittle metals are incapable of being forged.
? The forging process does not allow for finishing.
? The size of jobs has changed.
ABOUT KEVA
Keva Casting is a professional casting company that focuses on Construction, Machinery, Automobile, Hardware, Pipeline and many other industries.
We provide top quality products with the best service based on our complete production chain including our own mold design, advanced production techniques, and full management of the supply chain. Keva Casting has two factories located in Zhucheng, China's Shandong province.
We use "shell molding", which is a new technique that has been developed in recent years.This new technique has simplified production procedures and reduced air pollution compared with traditional sand casting and investment casting. Shell making and core making are faster to ensure production in enormous quantities. The dimensions and surface finishing are satisfactory for all kinds of industrial requirements. Besides supplying our own formwork & scaffolding systems, our casting products also supply OEM services in various industries.
