Cold Forging: Cold Forging Extrusion Process Explained
Cold forging parts are increasingly becoming popular in the market. From packaging products to machine parts, there are so many metallic materials that are being produced using this technology. But have you ever thought about how the cold forging extrusion process works?
You will be surprised that it is not a complicated process like it appears to be. In this post, we are going to take step by step the entire process of cold forging. Here are the main steps that makes a perfect cold forging extrusion process:
The first stage has a lot to do with the material selection. Depending on the product to be made, there is a specific material that’s needed. For instance, lets that the manufacturer has for making spanner such as a wrench. These are hardware tools that need to be very hard because of the condition they are exposed to. So, the material that is used for their construction is must be very hard. It may be an alloy of steel, such as stainless steel. If you use aluminum, the tools will become blunt very quickly. That’s just an example of why the choice of the material matters.
Designing and Making Dies
The second step in the cold forging extrusion process is the making of the dies. This is a very important factor to consider when cold forging. It is the dies that give the tools to be forged the shape and the size. The design of the die and the making is quite a complex exercise that requires hi-tech machines. You need the machining equipment for the dies.
With the material and dies, the manufacturing is now for the compression or striking process. This is where the workpiece or the material to be forged is put on the due. The hammer of the punch gets the striking force from the hydraulic press machine. The force is measured based on the hardness of the material being forged. For hard metals such as steel and iron, a lot of power is needed.
Flash and Finishing
These two stages are done together as one. Flashing is the removals of the excess metal left outside the dies after punching. After flashing, you will be left with the product, but you will need to do some finishing work. Remove all the awkward-looking parts to remain with the perfect shape of the expected products. With that, the product will be available in the market for sale.
