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.
Closed die forging is commonly used in nowadays for many improtant metal components. On one hand, is that it can product metal products with good properties. On the other hand, the price of closed die forging is also competitive than casting. In other words, closed die forging also has economic advantages.


Before forging, we will first need to cut the equal billet according to the size of products. Normally, the waste of material after forging is the flash. So comparing with casting or machining, closed die forging requires less material, thus material cost will be saved. Take a round ring for example, we can make it by forging or machining. If machining, the all corner and the center material will be wasted. But with forging,we can forged to the sizes with minimum waste.
Linear dimension
Linear dimension,or size,it is to point to the distance between two points,such as diameter,radius,depth,width and height,center distance,etc.To express the dimensions of drop forgings exactly,lots of linear dimensions will be show in a drawing.After finish production of products,we will test all these linear dimensions by vernier caliper or digital caliper,to check if these dimensions are within the required tolerances.For outer diameter,it will be more accurate to use outside micrometers.

Angular dimensions 
Angular dimensions are usually shown the size of Angle,like 30,such angular is tested by universal bevel protractor.
To remove the stress and improve mechanical properties of drop forging, heat treatment will be done after forging. Such heat treatment can be normalization, tempering, quenching, temperting&hardening,ect.To test the heat treatment result,we may test the tensile strength,yield stength,enlongation,hardness,among these mechanical properties,hardness test is usually used for drop forging.Today,we will introduce common hardness testing methods for closed die drop forging.

Both briness hardness and rockwell hardness are all the testing standard for drop forging hardness.Although the testing methods of them are not the same.But either of them can be adapted to see the hardness result of drop forging products.To ensure correct testing result,for one drop forging product,we should testing the hardness in different sections and check if heat treatment of drop forging is done in a good way.
Although the cost of drop forging dies may be relatively high,for piece price, it is very cost-effective. With drop forging process, the metal products can not only be in a low cost, but also win tough and durable characteristics. So that is why people say drop forging has low recurring cost and is the most beneficial production method for long runs. Of course, small quantities can be also offered, but more economocal with increased volume. Compared to cast or machined process, drop forging can produce metal products with a high strength-to-weight ratio. Also, it has less chance of flaws and low injection rate.

So,when you are interested in sourcing for drop forging supplier. CFS Forge can be your one stop shop. Our quick turnaround times and impressed services are the best in drop forging industry.
Steel forging is a metal forming process of shaping metals using the compressive force.The steel forging process is a bifurcated depending on the temperature at which it is preformed.Steel forging helps in shaping of the molten metal onto desired shape and size.It is one of the essiontial techniques in industry that are majorly reliant on machineries.Steel forging has gone simpler with the time.Main classifications of steel forging are carbon steel forging,alloy steel forging,stainless steel forging.

The traditional ways of steel forging lacks in various aspects.From being low on durability to prone to corrosion,there are numerous drawbacks.Metal enforced with steel can go a long way in terms of durability and evading corrsion.Closed die forgings for precison components are high on tensile strength.The imposed metals are used in the forging process of disc and sleeves that make cost conscious and quality product.
age hardening for steel forging
Age hardening,also called precipitation hardening,is a type of heat treatment commonly used for steel forging.Its name comes from the point in the hardening process in which the 
steel forging is aged,can be heated for an extended of time or keep it stored at a lower temperature for an extended period before use to form precipitates.This treatment is used on malleable alloys,such as steel for closed die forging.

Age hardening process will prevent the plastic deformation of steel forging parts.Thus,to increase the strength and other properties of products,but plastic deformation and toughness is low.Alloys created by the age hardening process have many uses,especially in applications where high strength and good performance at high temperatures are needed.If you need to make your parts in steel forged with age hardening treatment,also pls contact us. 
One of the most popular forms of forged metal is steel forged. Forged steel is an often used metal for forging because it is a very sturdy steel that can withstand the high heat that is required by the forging machine to make the metal malleable enough to shape. The metal is warmed to a high degree of heat because when you drop forge metals the metal is placed in the machine and a hammer press slams down onto the metal, forcing it against the die. The heated malleability of the metal combined with the force of the hammer shoving the metal against the die usually makes shaping forged steel relatively easy. Because of this ease of shaping the sheets of metal can be processed into their required shapes pretty quickly.

Thus,we can see steel forged products will no matter give you a price advantage,but also the properties are also quite reliable.

closed die forging optionClosed die forging is a form of impression die forging that uses two or more dies.It does not depend on flash formation to completely fill the die.Material is formed in a cavity that allows little or no escape of excess material, thus placing greater demands on die design. More elaborate die designs provide for more complex shapes than the open-die forging process. A variety of metals and alloys cans be forged using closed die forging process.

Closed Die Forging is largely focused on extremely high quality applications.Closed die forged materials are required where strength,reliability and resistance to fatigue are top most considerations.As such,forged materials are found throughout the automotive,aerospace and defense industries. 
Before placing an order,you will first get several quotations from potential closed die forging suppliers,some are manufacturers and some are trading companies.Importing closed die forging from China has been a popular trend for clients for its price advantage.And it has been too easy for purchasing manager with the sign-off to pick the "cheapest" 
quote without understanding what quality and partnership he is getting.

What we would like to remind you is that it will be a big mistake if just choose your closed die forging supplier who provides you the cheapest quotation.Just as a Chinese going says:"You get what you pay for".For distance factor,foreign customers can only find closed die forging suppliers from search engine.It is not actual for them to visit the potential suppliers right away for high travel expense.So quotation is the most direct factor they can consider a supplier.As a closed die forging company,we suggest more consideration factors,for example,if the supplier is manufacturer or not,what the capabilities are,lead time,ect.All these factors will help you to choose a most suitable supplier in a comprehensive way.Well because that's what we have here and if we quote a customer for closed die forging,we must make it work and work to the best of it's ability for it to be a profitable and sustainable project.
