Technical Specifications: Closed Die Forging

Closed die forging uses a controlled procedure with a culmination of alloys and heated metals to create the desired shape. Without an appropriate forging die lubricant, effective and economical closed die forging is unattainable. To know more about the technical specifications of this type of forging, please read on.

Mechanical Characteristics of Closed Die Forging

Alloys Used

Closed die forging is a type of forging that has exceptional mechanical characteristics – one of which is adaptability to the different kinds of an alloy such as copper, bronze, and aluminum. Aside from allows, it can also adapt or mold various kinds of steel like stainless steel, tool steel, and alloy steel.

Specifications

When using closed die forging, the tooling division must go through the center of the forging and should not run through the side. The reason for this is that the forging must be detachable from its divisions.

The different cross-sections must be equal to avoid extreme disparities in the flow of the metal. Additionally, a closed die forging uses low and wide rib features. To avoid quick tooling cracks or wear in forgings, manufacturers use large radii. Moreso, an ample and suitable draft angle should be provided wherein compliance of the 5° to 7° for steel and 3° for aluminum are mandatory.

Benefits and Finishing Options

Closed die forging is known for its economical procedure compared with welding assemblies. Other notable benefits include high production speed, use of highly homogeneous steel and alloys, and high rating when it comes to good repeatability. As for the finishing options, closed die forging allows blasting, vibra-polishing, hot-dip galvanizing, and electrolytic zinc plating.

Factors that Guarantee Only the Finest Forging Die

The finished product of a closed die forging is affected by several factors. The most common of which is the accurate process of application of die lubricant at proper intervals. Similarly, the forging result may also be affected by the decrease in friction during the forging procedure. Friction can satisfactorily be decreased by using appropriate polished dies and die lubricants.

The Simple Guide to Investment Casting

If you are in an industry that uses food processing equipment, valve components, power generation equipment, hydroelectric facilities, or furnace parts, chances are that you have heard the term “investment casting”. But what is investment casting? And more importantly, why should you use it?

What is the Investment Casting?

A high quality investment casting can be found at Ferralloy Inc

Investment casting (also known as lost-wax casting) is an industrial process based on one of the oldest known metal-forming techniques. It was developed over 5500 years ago and continues to be an integral part of metalworking to this day. Investment casting takes a wax outline of a part and coats it with a ceramic material. It is then heated until the wax is melted out of its center. Molten metal is then poured into the hollow ceramic mold. The metal hardens, gets broken out, and the part is made.

Why Should I Use Investment Casting?

There are numerous explanations why people decide to use investment castings. Here are the 5 main reasons why you should consider the investment casting process:

  • Practically any metal can be manufactured by this process. This includes aluminum alloys, bronze, tool steels, stainless steels, cobalt alloys, carbon steels, Hastelloys, and precious metals.
  • It can manufacture extremely complex parts that would otherwise be extremely difficult or impossible.
  • It creates very smooth surfaces with no parting line. As a result, only minor machining is required.
  • Very thin sections can be made. Castings with sections as narrow as .015 inches have been manufactured with investment castings.
  • It produces high dimensional accuracy with tolerances as low as .003 inches.

What Industries Use Investment Casting?

Due to their massive benefits, investment castings are used in a wide range of industries. The aircraft and aerospace industries use investment castings for turbine blades, vanes, and structural components such as fan exit cases and struts. Investment castings are also used for valves, fittings, sporting goods, pumps, engines, turbines, military and small arms applications, airframes, missile controls, medical equipment, dental fixtures, gears, jewelry, machine tools, office machines, and numerous other complex parts.
