Forging vs. Extrusion: Basics You Should Know

If you visit metal parts manufacturing factories, you will realize many methods of forming metals parts. But the most commonly used metal forming methods are forging and extrusion. So what are the major differences between the two? This article will discuss the forging and extrusion methods, their differences, pros, and cons. Check out the following:

Forging

Forging is a manufacturing method where metals are exposed to massive compression forces to reform to different shapes and designs. Various ways are used under the forging method depending on the temperature needed for the metal parts to become flexible and ready for reformation. The most common methods used are the hot forging process and the warm forging process.

The hot forging process is where metal parts are heated under very high-temperature ranges; above the recrystallization point. Metals that are formed through the forging method possess unique, durable features.

Pros of Forging

  • Metals parts produced are durable and not easily worn out
  • Metal parts have great structural and mechanical strength due to the bold grain structure formed after heating.
  • Metal parts are shaped easily due to the plasticity nature, hence reduction in labor
  • The method Eliminates surface porosity and internal voids because of the isothermal process used in surface finishing.

Cons of Forging

  • Forging, especially hot forging, is limited to simple shapes
  • It is challenging to acquire and maintain tight tolerance
  • Metal parts forded are prone to oxidation because of high temperatures.

Extrusion

Extrusion is a manufacturing process where a billet of material is pushed and drawn through a die to create desired shaped parts. Metal parts are pressed at high pressure. Hot extrusion helps eliminate pores and voids in the workpiece that can cause weakness, while cold extrusion gives the workpiece a better surface finish, strengthen the parts, and gives it greater geometric accuracy on smaller short lengths of cuts made.

Pros of Extrusion

  • The process is fast and efficient for high volumes

Key Features Worth Looking At In Automotive Forging Parts

Are you looking for automotive forging parts for replacement purposes? Is it your first time to encounter such an experience? Most probably, you are confused and frustrated in determining what makes the best automotive forging parts. Considering that it is your money at stake, you must not make any mistake in choosing the respective automobile forging parts. Here are key features that must guide you in choosing automotive forging parts:

Compatibility

First, you need to be certain about the model, shape, and form of the automotive part that you want to replace. This is for the sake of ensuring that you only get a compatible option and nothing less. The automotive forging parts you choose should be compatible with their respective parts of the application.

Material Used

You might have realized that automotive forging parts can be made from assorted materials depending on customer preference. However, there is a major difference between assorted metals used in making automotive forging parts.

Brand

It is likely that you are in the aftermarket sector looking for some automotive forging parts. If that is the case, then you should be on the lookout for the brand of the parts you intend to buy. The aftermarket sector provides you with assorted options hence ample convenience. However, be sure to look for a brand that is appealing and made of the best quality.

Customized or Not

Sometimes you might require an automotive forging part that is in a specific manner, hence the need for customization. The good thing is that a majority of manufacturers and forgers give room for customization. That way, you can get the specific order that you placed. It is, however, important to consider the level of precision in customizing such parts.
