Three Essences of Metal Forging Process

Metal forging process is one of the traditional Chinese metal crafts. Craftsmen cut metal materials such as gold, silver, and copper into circular plates, forged them by using the ductility of metal, and finally forged them into utensils.

The development of metal forging process to the Tang Dynasty has reached an unprecedented height in terms of the shape of the utensils, the fineness of the craftsmanship and the gorgeous decoration of the utensils. The handed down metal forging craftsmanship is rare among the Han people, but in minority areas such as the Bai nationality in Yunnan and the Tibetan nationality in Tibet have been prosperous, and have formed their unique traditional handicrafts.

The tools of metal forging process mainly include: hand hammer (different shapes and sizes), anvil, furnace, bellows, hand pliers, various chisels, vices, spray guns, welding torches, crucibles, etc. Besides, there are cast copper molds, multi-function files, large and small iron shears, long-handled wire brushes, etc. for various purposes. In addition, there are cast copper molds, multi-function files, large and small iron shears, long-handled wire brushes, etc. for various purposes.

At present, the metal forging process of stainless steel hydraulic cylinders manufacturers has made great development on the basis of inheriting the traditional forging process, which is mainly reflected in the changes in the process caused by the improvement of manufacturing tools. For example, craftsmen from Bai nationality learned to use air hammer to preliminarily forge the shape of tools. Modern advanced tools are used to serve the traditional process and improve the production efficiency. The traditional manual forging process is mainly divided into three processes:

1. Hand-forged primary shape of metal forging process

According to the size of the vessel, it is necessary to cut the round metal plate that fits with it, and make it into the initial blank of the vessel by forging. That is, place the round metal plate on the anvil, adjust the forging strength and inclination angle, and evenly forge while turning, and forge every part of the round metal plate.

If one or two places are over forged, the thickness of the metal plate will be uneven, and even cracking may occur. Other places may also cause the cracks to roll over, and the edges of the vessel may also be uneven. In the forging process, pay attention to annealing to soften the hardness and prevent cracking during custom metal forgings.

2. Manual forging of metal forging process

After the initial blank of the vessel is formed, the next step is to use anvils of different specifications to forge specific shape transitions, which requires careful forging.

Hand forging is also used to forge with a hammer while turning the utensils. Different shapes of utensils use different hammers and anvils. Some hammers are used to find the shape, some are used to hammer the turning surface, and some are used for detailed finishing.

3. Process effect processing and component welding of metal forging process

The custom forged parts process effect mainly refers to the process treatment of the surface of the utensils: including chisel engraved lines, decoration of traditional patterns, production of relief effects, etc. Some utensils use the texture effect of forging and hammering, which is natural and simple, and has a strong and rough natural charm.
