Press forging defined as the process of shaping a metal that is placed between two dies by applying mechanical or hydraulic pressure. so now let us understand the key pros and cons of press forging to understand more about it.
Advantages of press forging :
- It deforms the workpiece completely.
- The compression rate of the workpiece can be controlled automatically.
- More economical for high volume productions.
- Any size and shape can be created.
- Requires less draft and produces lesser scrap so better dimensional accuracy.
- Greater accuracy in terms of tolerance within 0.01 to 0.02 inch.
- This operation is completed in a single squeezing so save time.
- The plastic deformation goes deep into the centre of the workpiece provides uniform deformation.
- The capacity of presses ranging from 500 to 9000 tons and the number of working strokes per minute can be high as 40 or even 50.
- It is suitable for the mass production of nuts, bolts, rivets, screws, brake levers, valves.
Disadvantages of press forging :
- The initial cost is higher because the cost of the crank press is always higher than of an equivalent hammer.
- The difficulty of descaling the blank.
- It is economical when the equipment is efficiently utilized.
