Forging
1. What is the Precision die forging?
Precision die forging (also called “Cold die forging”)is a processing method that uses forging equipment to place a metal blank in a mold with a certain shape and apply pressure to cause it to plastic deform to obtain certain mechanical properties, a certain shape and size.
Important parts in related machinery with high loads and severe working conditions are basically made of forgings.
2. Why Choose Precision die forging ?
Precision die forging technology is based on the success of multi-disciplinary high-tech technologies such as new materials, new energy, information technology, and automation technology. It transforms traditional forging blank forming technology from general forming to high-quality, efficient, and high-precision , lightweight, low-cost, pollution-free forming.
Compared with ordinary die forging, precision die forging can obtain forgings with good surface quality, small machining allowance and high dimensional accuracy.
At present, precision die forging is mainly applied in two aspects:
● The first is to refine the blank, that is, using precision technology to replace the rough cutting process, and directly processing the precision forgings to obtain finished parts.
● The second is precision forging parts, that is, finished parts are obtained directly through precision die forging.
3. The Advantage the of Precision die forging
● The material utilization rate is high, precision forging has a small amount of flash, and the material is plastic deformed into the required product shape according to the set process. Some parts require only a small amount of processing after precision forging, while some parts can be put into use directly without processing.
● The performance of the parts is good. The metal fibers of the parts produced by precision forging are distributed along the contour shape of the parts and are continuous and dense.
● The product has good dimensional consistency and high precision.
● Instead of the silica sol precision casting process, precision forging for parts with relatively simple product structures has lower costs and better quality than casting.
1. what is the Free Forging?
Free Forging, also known as open die forging or Smith forging, is the process of deforming a sheet of metal by striking it with a hammer, In the free forging process, a forging blank (usually a metal block or rod) is heated to a temperature sufficiently plastic and then formed into the desired shape using equipment such as a forging hammer or forging press.
2. Pros&Cans of Free Forging
Pros:
● Flexibility: Free forging is suitable for workpieces of various shapes and sizes because there is no need to make complex molds.
● Material saving: Since there is no mold, no additional materials are needed to make the mold, which can reduce waste.
● Suitable for small batch production: Free forging is suitable for small batch production because mass production of molds is not required.
Cans:
● Process doesn't always produce consistent results or desired features : The quality of free forging depends on workers' skills and experience, so the requirements for workers are higher.
● Slow production speed: Compared with die forging, the production speed of free forging is slow.
● Not suitable for forming intricate, precision parts or other close-tolerance application: Without the assistance of molds, shape and size control in free forging is difficult and requires more subsequent processing.
