Ultimate Guide to Rod Building vs. Casting

I often get asked, What is the difference between forged vs powdered metal vs casting

There are many nuances to each of these methods and processes, but here's a quick overview of the differences

Forged rods are made by hand-hammering a blank into shape. This produces a very strong rod, with good distribution of stress throughout the blank. The blank can be either solid or hollow, depending on which method you choose to build your rod from (see below)

Powdered metals are produced by adding material to a previously cast blank. The added material makes it possible to make very light-weight rods that have very high strength because they are not as dense as an unalloyed blank would be. This allows the use of less expensive materials such as carbon fiber and epoxy resin for some models

Casting is similar in principle to forging except that instead of hammering out a blank from a block of metal, molten aluminum is poured into molds that have been made beforehand. Once cooled, these molds can be used again to cast larger batches of rods very quickly.

What is Forging Service

Metal forging is a manufacturing process in which metal is heated and placed under pressure to produce parts with a desired shape. Forging can be done using a variety of tools and machines, such as hammers and presses, to shape the metal into the desired shape. The process of forging can produce parts that are stronger and more durable than those made using other manufacturing methods. Many different metals, including steel, aluminum, and brass, can be forged using this process.

How Does Forging Service Work

Once we open the die/mold of forging process and get ready, then we start forging mass production.

The processes of forging are as below:

1/ The metal is heated to a high temperature in a forge or furnace. The heated metal is placed on an anvil or forging die.

2/ The metal is struck with a hammer or press to shape it into the desired form.

3/ The metal may be reheated and reshaped multiple times to achieve the desired shape and properties.

4/ The metal is cooled and hardened by quenching it in water or oil.

The forged metal parts normally need further processed by machining, heat treatment, or other methods to achieve the final desired properties and finish.
