Design Guidelines for Casting Design and Process Selection

Date: 11 Oct 2006 - 12 Oct 2006

Venue: Seminar Room, Level 1, Valley Block, SIMTech, 71 Nanyang Drive


Metal casting is the most effective and economical way of producing shaped metal components. However, it is essential that component designers and casting producers understand how to get the best performance from both the castings and the processes used to produce them. The unique feature of the casting process is the transformation of a liquid metal into a solid casting. The process of solidification is crucial to the structure, properties and integrity of the casting and, therefore, to its performance in the application for which it is intended. The production of a perfect casting requires that it be designed with an understanding of the influence that both the process of production and the design have upon solidification and the occurrence of defects such as porosity and inclusions.

The first day of the workshop will first define what we mean by casting before classifying the range of processes available. This will be followed by a review of the range of casting processes available to the designer with emphasis on those processes suitable for producing precision castings in terms of dimensional accuracy, surface quality and metallurgical integrity. The emphasis will be on those processes suitable for the production of castings for automotive, aerospace, electro-mechanical and marine components. Processes that will be covered include: precision sand casting processes (shell moulding and the Cosworth process); the ‘Lost Foam’ process (also known as EPC process); the ‘Lost Wax’ process (also known as investment casting); the die casting processes (including gravity, low-pressure and high-pressure processes); thixo-casting and liquid metal forging. The process descriptions will be supported by video clips where appropriate. The second day of the workshop will concentrate on the capabilities and limitations of the casting process from a design perspective; process related defects to include solidification, inclusions and gases; the relationship between design and casting defects; ‘good’ versus ‘bad’ casting design; design guidelines for specific processes, for examples, sand casting, die casting and investment casting; and the benefits of CAE and process modelling for casting product design and development.
