Closed Die Forging - SK is a closed die forgings manufacturer and supplier from China

In the past decade, SK upgraded the closed die forging technology and invested in closed die forging research. We have a very professional technical team in closed-die forging. We are also a forging manufacturer to many well-known auto groups, including Honda, Audi, ford, GM and so on.

What is Closed Die Forging?

Closed die forging is a forging process that demands high precision and one-time forming shape. In some aspects, closed die forging is similar to precision forging. Closed-die forgings can be done without flash. This greatly improved working efficiency and reduced material costs. Closed die forging was also called impression die forging. Sometimes closed die forging used two or more molds to forge the metal. This will help the forging products directly to its final shape without flash.

Materials used for Closed Die Forging

As we mentioned above, the materials of closed die forging and open die forging are basically the same. They could forge a variety of types of materials. The most common materials are carbon steel, alloy steel, stainless steel and copper alloy. SK could forge the materials from United States, Japan, Germany, Australia and Italy.

Features of closed die forging

1. The closed die forgings have high strength and precision surface treatment. Usually closed die forgings do not need machining process.

2. Closed die forging need high precision molds. This is the most important part in closed die forging.

3. For some forging products, closed die forging could save raw materials and reduce the products cost.

Applications of closed die forgings

Closed-die forgings are mainly used in some key components of automobiles, aircraft and precision machinery or some complicated shape forging products.

Some Useful Guide of Closed Die Forging 

1.FAQ about closed die forging from FIA official website

Closed die foring and impression-die forging of steel, aluminum, titanium and other alloys can produce an almost limitless variety of 3-D shapes that range in weight from mere ounces up to more than 25 tons. Closed die forgings are routinely produced on hydraulic presses, mechanical presses and hammers, with capacities up to 50,000 tons, 20,000 tons and 50,000 lbs. respectively.

2. A patent introduce the closed die forging process from freepatentonline.

A closed die forging press includes a die set having a stationary die, a movable die in facing-but-spaced-apart relation to the stationary die along a press axis and defining a workpiece volume therebetween, and an exterior constraint extending circumferentially around the workpiece volume.

3. Some discuss about closed die forging technology

Closed-die forging is the shaping of hot metal within the walls of two dies that come together to enclose the workpiece on all sides.
