Let’s learn more about the metal forging process at 83MEC in the article below.

1. Overview of forging technology

1.1 What is the essence of forging technology?

Forging is a processing method that has been applied for a long time; the development of technology has improved the forging process with modern and specialized machines and equipment to support traditional forging methods, thereby achieving higher production efficiency, ensuring in terms of quantity and quality. The essence of the forging process is to use external forces applied to ductile materials to change the workpiece with the required shape and size.

Currently, there are two main forging methods: free forging and Impression-die forging (closed-die forging). Different forging methods are flexibly applied based on the product’s characteristics to be processed. As follows:

– Free forging is the process of processing metal under the action of external force through a hand hammer or machine hammer to deform the workpiece. The workpiece is heated to a specific temperature to convert the metal billet into a plastic state, and then an external force is used to change the shape of the workpiece as required.

– Impression-die forging (closed-die forging) is a machining process that deforms the metal inside the mold. Under the stamping force of the device, the metal is deformed in the mold cavity.

* Features of the free forging method:

– Machining parts have low precision, and surface gloss is low.

– It is difficult to be consistent in each part’s quality and metal properties, so it is only suitable for processing simple parts, small quantities or complex non-shaped surfaces.

– Long processing time, low productivity

– The quality of the product depends mainly on the workers’ skills. 

* Compared with free forging, impression-die forging has the following characteristics: 

– Impression-die forging provides higher forging accuracy and quality than free forging.

– Capable of machining complex parts.

– High productivity

– Easy to mechanize and automate.

– However, the high cost of mold-making makes the forging method suitable for mass production.   

2. What metal forging methods does 83MEC have?
