Now there are 7 production lines of closed die drop forging in our factory with forging presses ranging from 300t to 2500t.All these forging presses can be used to forge products in different dimensions.From the point of most people's view,the tooling cost of drop forging is higher than casting tooling.It is without doubt that forging cost more due to its nature and advantages.But in spite of this,you get what you pay,it is rewarding.Our production capabilities are not limited to drop forging,but also machining is also one of our advantages.To serve our customers better,we are also equiped with some machining equipments from drilling machine to CNC,so that machining can be done in our company.

Besides,our in-house heat treatment will also help us to offer you our competitive prices.So comparing with other forging factories and trading compaines,we are always your top and wide choice for drop forging products.Any interest in such process,just pls contact us!
As a professional closed die forging company in China,we are equipped with seven closed die forging production lines for the requirements of different shape products,that is why we can customize closed die forgings for all the industry applications.

In our forging workshop,forging equipment for each production line is different,currently,we have forging presses in 300t,400t,600t,1000t,1250t,1600t,2500t.Forging presses with larger tons are used for closed die forgings in large shapes&dimensions.Also production steps may be varied from the shapes of products.For shaft type products,steps of closed die forging process are just five,that is cutting billets,heating by medium frequency furnace,drop forged by forging press,trimming by punching machine,last step is shot blasting.Thus,we will see a forged shaft product is finished,such shaft type product is the most simple way to make.
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.
Although closed die forging can produce the strongest steel parts and other advantages,there are only few closed die forging factories in China for its less application than casting.So lacking a good supplier for closed die forging parts has become a common problem for foreign clients.Today a customer from Australia contacted and told us that he is a forging distributor and as now they are getting more and more enquiries for these small closed die forging(mould forging) parts,but they do not have a good supplier.So they are in urgent to find such a supplier.

Were you able to find a good source for closed die forging parts? You may find out there are very few Chinese manufacturers that could satisfy your companies' needs. We are a Chinese company with our own forging factory in Ningbo China.We build very precise and high quality closed die forging parts exclusively for companies from US, Canada, UK, Germany,Italy etc.As a China Closed Die Forging Maker,We have very good equipment including forging equipments from 300t-1600t,machining workshop for forging dies and forging machining.Our forging engineers are good at English and forging technologies,so our company is easy to communicate with. Feel free to let us know if you are finding a closed die forging supplier in China.
Closed die forging is a metal forging tecnology for precision parts.Such process is usually considered especially for safty factor because of its good performance and strength.So closed die forging is quite popular in producing automotive and non-automotive sectors.And we can see a lots of closed die forging factories in different scales all over the world,some are for steel forgings,some for aluminum forgings,and others are for copper forgings.There is no doubt that advantages of closed die forging over investment casting are obvious,so many people may put forward a question:"Are closed die forgings expensive?"
In the past forging production,our 1600t forging press is limited to closed die forgings no more than 30kg.To meet our customers' demands for larger products,we imported 2500t automatic hot forging press for closed die forging production.Below are the photos of 2500t automatic hot forging press:
Closed die forging requires two or more dies for production,which are also referred to as tooling.These dies first must be manufactured with CNC machine to reach high accuracy. The billet will be heated up to proper temperature for well deformation and is then pressed or hammered between these dies.

The restriction of the metal flow inside the dies allows the production of parts that are more complex in shape than a part being produced by the open die process. Additionally, closed die forging process allows for closer tolerances than those produced in open die(see the difference between open die forigng and closed die forging).Relatively simple shapes can also be processed this way,but the decision is usually driven by economics and meeting some of the conditions listed below.
Our company customizes different kinds of closed die forging products,for instance,drive and axle components for the commercial automotive industry,drilling attachment for mining technology,forged fittings for oil and gas industry,as well as other complex geometrical structures for construction&agricultural machinery,offshore industry,aeroplane industry,ect.

Wide range closed die forgings with superior quality and reasonable price from our company bring us an excellent reputation all over the world,so we are now growing fastly and exporting products at an increased capacity.The use of high-grade steels means that our products offer a particularly long working life.
closed die forging dies
Closed die forging dies,normally consists of forging dies,trimming dies and sometimes flat dies.Like dies for the punch-press,are of several different types.Perhaps the most simple form of closed die forging die would be a pair of dies for producing a simple round forging,as,for instance,a gear blank.These dies would require a central impression turned in each of the dies of the pair.Before using the dies,a square plate of steel is worked under the hammer,drawing out a short shank at the side,and "knocking down" the corners.This roughly shaped block of steel is held by the shank and placed between the dies and thus brought to shape.


The most common form of closed die forging die,however,is the one in which there is a central impression to shape the forging,and a side impression,called the "edger," "break-down" or "side-cut,"that helps to properly distribute the hot steel(refer to select die material of closed die forging).To make clear the use of these two sets of impressions,a closed die forging die of this description may be likened to a drawing of the finished forging,in which the outline of the central impression would resemble the plan view of the forging,and the two halves of the edger would correspond to the side elevation of the forging.Of course this illustration is not literally correct,but it expresses the general idea.The edger is always on the right-hand side of the die,and the steel bar is struck first in the break-down,edgewise,and then turned and struck flat in the impression,alternating in this manner until the forging is "full." 

According to the advantages of closed die forging,it has become one of the main metal forming processes in modern manufacturing.For its wide range of material specifications and 
shapes,closed die forging can be useful for lots of metal components,such as componets for aeroplane,cars and heavy trucks,shipbuilding,ect.

With the characteristics of closed die forging,we can make precision components with different wall thickness,complex shapes,narrow tolerance.And we are all equiped with full range of machining equipments,so machining is also feasible in our company.Maybe sometimes you could also consider casting process instead,but by comparison,there  are both price advantages and quality advantages over casting,we will no need to worry about production defect.

1. Background

Metals and alloys are able to be formed into desired shapes by plastic deformation.In deformation process,they also produce a wide range of properties particularly strength and toughness.The working of the metals into shapes by means of closed die forging methods refines grain structure,develops inherent strength giving characteristics,improves physical properties and produces structural uniformity free from hidden internal defects.What's more,the special feature of flow lines along the contour of the clsoed die forging produce marked directional properties.These features in closed die forgings give the automobile designers great confidence regarding the reliability of the vehicle.Learn more about advantages and disadvantages of closed die forging in detail...
