6 Main Steps For Cold Forging Manufacturing Process

The cold forging manufacturing process is probably one of the easier and shortest in the forging industry. As the name suggests, the cold forging process works on the metal at room temperature. Therefore, the heating process is eliminated with the forging technology.

For starters, there are things you need to get right for a successful cold forging manufacturing process. One of them is the right steps. In this guide, we are providing you 6 steps to follow during cold forging:

Step 1: Preparing Workpiece

The first thing you need to do is to prepare the metal that you want to forge. The workpiece could be any material that can be cold forged. You need to lubricate it to prevent it from sticking to the dies once it has been forged. The lubricant also keeps it cool during the cold forging process.

Step 2: Place Workpiece On Dies

With the workpiece ready, now it’s time to prepare for the forging process. You need to ensure that the die or dies are in place on the pressing machine. It is also important to ensure that you have the right mold/die. It is the die or mold that gives the metal being forged.

Step: 3 Forging

The forging state is also called the stroke stage in the cold forging manufacturing process. This is the stage where the workpiece is pressed against the dies. The striking hammer of the punch uses compression force produced by the hydraulic press machine. The amount of the striking force is determined by the metal being forged. The harder the metal, the higher the compression force.

Step 4: Flash

Flashing is the process that comes immediately after the forging stage. This is where excess metal that could fill the die is removed. The workpiece is usually bigger than the actual material to be formed to ensure standard weight and size are achieved. The flash can be recycled for other uses.

Step 5: Part Removal

The fifth step should be the removal of the formed parts from the die. Do note that the part is still very hot because of the striking impact. This means you cannot use bare hands. Modern technology enables the use of robotic arms to fix the removed forged parts.

Step 6: After Shaping

The last step is finishing or shaping the product. This is where you give the part a very fine surface by trimming the exterior. All the awkward shapes corners are fixed to get the best shape of the part.
