Bulk & Sheet Metal Forming Processes - CERTIFICATION 2022

This Course covers metal forming and related manufacturing processes, emphasizing practical applications. As a high-value-adding category of manufacturing, metal forming is increasingly important to the core competency of manufacturers and suppliers. A thorough survey of metal forming processes and metal forming mechanics will be performed, including bulk deformation, sheet metal, and operations. Design considerations are fully integrated into the course and are presented with every process. A large number of real-world case studies are presented to the attendees to emphasize course content.

Forming Process also known as Metal Forming is a large set of manufacturing processes by which raw material is converted into a product. In this process, we apply stresses like tension, compression, shear, etc. to deformed the raw material. The example of forming processes are sheet metal manufacturing, forging, rolling, extrusion, wire drawing, and so on

Metal forming processes are an essential part of our society, and without them, our society would come to a grinding halt.

The products and components created by the different metal shaping techniques are used in creating everything from scaffolding and heavy machinery to designing and creating microprocessors and artificial intelligence.

When it comes to metal forming, there are several processes to choose from, with each offering its own list of benefits and detriments, each suited to certain applications, and each suited for different types of metal.
