For many metal parts, there are generally two methods: casting and forging. Casting is mainly suitable for the production of parts that do not require high precision and quality, but forging is different. Forgings are better than castings, because castings do not Change the original structure and mechanical properties of the metal, and its fibrous structure increases the strength and toughness of the metal, which is very suitable for those easy to wear parts. At the same time, the forging is more conducive to welding deformation and plastic operations, and after these After the steps, its performance will not change much. Therefore, forgings are widely used in modern industry.

However, at present, forgings have relatively high requirements for equipment. The larger the scale of forgings, the higher the requirements for equipment. However, there are still greater difficulties in the manufacture of forging equipment in China. Although there have been breakthroughs, the There is still a big gap in the world's advanced level, so when choosing forgings, we must pay attention to choosing those strong forging plants, so that we can guarantee.
