Facts of Closed Die Forging

When purchasers need a metal forming process for their precision design or products, they may have lots of considerations, such as quality, economy, ect. With the development of modern industry, there are all kinds of metalworking processes for choosing, such as casting, forging, powder metallurgy, stamping, machining, ect. Each metalworking process offers a unique set of costs, advantages and capabilities. When safty and strength factors are required, closed die forging process will be your best choice. In fact, closed die forging is often the optimum process, in terms of both part quality and cost-efficiency-especially for applications that require maximum part strength, special sizes or critical performance specifications.

In fact,in terms of forging, there are also several kinds of forging processes available, such as open die forging, closed die forging, cold forging, and extrusion. However, here we will discuss the methods, application and bennefits of closed die forging process. We suggest you to consider this process when selecting the optimum process for your metal parts production.

History of closed die forging dates to at least 4000 BC and probably earlier. Metals such as bronze and iron were forged by early man to produce hand tools and weapons of war. The earliest recorded metal employed by humans appears to be gold. Small amounts of natural gold have been found in Spanish caves used during the late Paleolithic period which was around 40,000 BC. The forging of iron and steel continued until near the end of the 19th century for similar purposes and it is unfortunate that weapons of war are still produced by the forging process using more contemporary metals.

In modern production,there are not only economic advantages of closed die forging, but also other obvious closed die forging advantages, for example, closed die forging will obtain high strength and less defects, and the production efficiency is much higher. In a word, no other metalworking process can equal closed die forging in its ability to develop the optimum combination of properties. So closed die forging can be used in applications of mining industry, agricultural machinery, and other industries.
