Company Introduction

   Auspicium Co., Ltd. was established in 2003. We have the consulting associate agreement with FLOW SCIENCE INC. (http://www.flow3d.com) since 2003. Also, we hold routine training courses of FLOW-3D ^® in Taiwan, currently. 

The application of Computer-Aided-Engineering (CAE) in the metal casting industry will have an important role in companies that wish to remain competitive. CAE is a natural complement to Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) which are now well established. CAE applied to castings makes use of computer simulation to develop optimum methods for making castings. This allows manufacturing methods to be developed for the particular purpose of the casting with the optimum combination of cost, quality, and reliability. In the past only the largest companies could afford computer simulation. The development of relatively cheap simulation software and fast computers means that this now within the reach of much smaller companies. Auspicium give companies the possibility of obtaining the benefits of computer simulation using the experience of its highly qualified casting engineers without the investment required to set up their own facility.

Advantages of computer simulation
Casting is the quickest route from liquid metal to finished shape, and is often the cheapest. However its reputation for supplying high quality parts consistently has until recently not been the equal of other processes such as forging and extrusion. Modern manufacturing methods using automation and modern quality control management methods can provide specified quality levels consistently. However to get the most from the material being cast the casting process itself must be optimised which means knowing precisely what happens to the metal inside the mould, from the moment pouring starts to when the casting is removed from the mould.

In the past knowledge of shrinkage distribution has been obtained by fairly crude calculation methods based on trial and error and metal flow has been studied with water models and real-time x-ray studies; however these techniques only give partial answers (e.g. water models only show filling patterns and show nothing of solidification patterns) are costly, and are rarely used for solving industrial problems.

Simulation of the casting process on computers allows both heat transfer and fluid flow to be studied for the whole casting at whatever level of detail is appropriate. Indeed the importance of minimising even small levels of turbulence during filling to improve casting reliability, particularly of aluminium alloys, has been demonstrated in the last decade with running systems developed using computational fluid dynamics (CFD). The results of simulation can be interpreted using many parameters e.g. quality index, velocity of metal flow, shrinkage sites etc. using modern graphics to make the results easy to understand.. This means that different methods of filling and cooling the casting can be assessed in the office before a drop of metal is melted. The design of the mould including filling methods and solidification control can be specified and tested using software especially developed for metal casting. This software has been in use industrial foundries around the world for over 20 years.

Why you need Auspicium
Casting simulation software is readily available and has been made easy to use. However it still requires familiarization and experience to get the most from it. Also to make use of it efficiently it requires engineers who are knowledgeable about casting processes, the practical limitations of casting and how to get the most from the process. Thus while companies may easily afford the cost of the software and the computer systems themselves, to make use of the equipment they need engineers familiar with both the casting process and the software. This can take time to develop. To obtain the benefits of this modern production tool immediately Auspicium offer their services for companies who wish to evaluate the benefits of this approach on their own design of castings or who may not have sufficient work to justify setting up their own internal bureau.

Thus the problems companies may encounter when introducing modelling (CAE) into their operations are:
(a.) finding suitable experienced engineers;
(b.) assessing and choosing the most suitable software;
(c.) keeping the new technology up-to-date;
(d.) maintaining the facilities and modelling packages,
(e.) retaining key personnel once they are trained and experienced.
These problems will deter companies considering investing in CAE.
These problems can be avoided by using the services of Auspicium.
We can help because we use the latest technology and use advanced research based concepts to design running systems. And we offer the experience and knowledge of our professional engineers.
