Technology Infusion Programme (TIP) course on Forging Technologies for Production of Precision Components

Date: 13 Sep 2005 - 27 Sep 2005

Venue: SIMTech, Seminar Room, Valley Block, Level 1

Course Introduction

Metal forging is one of the most effective ways for the production of metal components via plastic flow of metal in forming process. The product development paradigm of metal forming involves the know-how and knowledge in material selection, process determination, tooling design and product quality control and assurance. This TIP course will cover the know-how in precision metal forming product development, including various forming processes. The course will also focus on cold forging process determination and tooling design. Furthermore, the metal forming plasticity and CAE simulation technology will also be introduced in this course.
