Seminar : Computer Aided Engineering (CAE) on the Processing of Plastic Moulding and Metal Forming Parts for Precision Engineering Industry

Date: 26 Feb 2009 - 26 Feb 2009

Venue: SIMTech Auditorium, Level 3

Introduction
Computer Aided Engineering (CAE) has been used for many years to enable design engineers to optimise product and process to shorten the time-to-market thereby reducing the defects of the products. However, the exposure to understand how to apply the CAE technique is very limited. The main barrier for such a limitation is primarily due to the high cost of CAE software and less fundamental knowledge in applying CAE for product and process designs in precision engineering (PE) industry.  
 
The objective of this seminar is to provide a  platform for both plastic injection moulding and metal forming companies to upgrade new technologies and enhance CAE capabilities through future consortium membership training programme. The seminar will also include presentations by expertsfrom Japan to share the latest trends and developments in the manufacturing of plastic and metalparts for the PE industry. Participants will gain a better understanding of the benefits and successful case studies utilising CAE simulation. 

Abstracts
Injection Moulding of Plastic Parts for Precision Engineering 
This session will cover an overview of the advanced injection moulding technology for automotive plastic parts, typical moulding process. Defects of injection moulded products  encompassing Weldmark, Silvestreak, Transformation, Shrink  will be shown with some methods for preventing these defects by CAE and others will be discussed as case study.  

Applications of CAE Simulation for Plastic Injection Moulding
There has been an increasing demand to utilise CAE to shorten product development cycle and product quality in tandam with the moulding industry moving towards high precision and multi-functional component moulding. The presentation will cover the technical challenges, benefits for moulding industry and successful case studies on new product and process development.

Advance in Metal Forming Technologies for High Precision Metal Components
For the purpose of matching the important requirements for manufacturing of metal components in PE industry in the near future, some recent topical advances in metal forming technologies will be shown for high precision metal components. This includes the forming of high precision/light weight parts, cold forging combined with stamping, cold rotary forming as well as incremental forming of sheet metal.

CAE Simulation for Metal Forming Parts and Its Applications
Finite Element Modelling (FEM) has been used for die and process designs the last decade. The major benefits are to reduce optimise the process and lead-time to the market. This presentation will illustrate the applications of FEM in various metal forming processes, such as bulk forming (forging), sheet metal forming and hydroforming.

About the Speakers
Dr Danno Atsushi graduated from Nagoya Institute of Technology in with a bachelor's degree in Mechanical Engineering. From 1964 to 2003, he has been engaged in R&D work on the high precision bulk-metal forming technology for manufacturing automotive components in Toyota Central R & D Labs. His R&D work includes rotary forming (gears, stepped shafts), forging lubrication (warm, cold), forging CAE (FEM simulation, knowledge based expert system) and some special metal forming processes.  In 1981, he obtained his PhD engineering degree from Osaka University. He was appointed as Director and board member of Toyota Central R & D Labs from 1995 to 2001. He has been working with SIMTech since August 2003 as a Visiting Senior Scientist, Forming Technology Group. He has authored and co-authored more than 50 original technical papers and took 25 patents on his R&D work.

Mr Suenaga Kiyoshi received his bachelor degree in Applied Chemistry Engineering from Iwate University. In 1971, Mr Suenaga joined TOYODA-GOSEI (TOYOTA Group Company) that supplied various types of plastic injection moulded components (internal and structure parts) for TOYOTA vehicle. He was engaged in different engineering and management roles in the company including polymer material selection, product design, moulding processing development for automotive parts. He is familiar with different moulding process such as injection compression moulding, two components moulding (sandwich moulding), in-mould printing, blow and extrusion moulding process. He was involved in many projects for the development of new automotive parts, including technology transfer from the product design to the mass production. He worked on polypropylene polymer material modification and compounding with talc, glass fibre, carbon fibre for precision engineering components. He has been working for SIMTech as a Visiting Research Scientist since 2008 responsible for developing plastic moulding technologies. 

Mr Chen Ge received his BEng in mechanical engineering from Tianjin University, in 1989 and his MSc in smart product design from Nanyang Technological University in 2001. He began his career as a plastic mould designer and injection moulding engineer in a based electrical connector company in 1989. Since 1994, he has been working in SIMTech as Research Engineer. He has been actively involved in various types of industrial consultancy projects on CAE simulation for the new moulding product development, mould design and moulding process optimisation. He has more than 15 years experience in the computer simulation and certified power user for the Moldflow and Moldex software. Over the past few years, he has been working with local contract  manufacturers to design and develop new plastic products and process using gas-assisted moulding process for the electrical and automotive applications. Currently, his research interest includes CAE moulding process simulation, process control and optimisation of micro moulding, gas-assisted injection moulding and microchip encapsulation. 

Dr Yingyot Aue-u-lan is SIMTech Research Engineer whose portfolio includes metal forming, cold forging, rotary forming and superplastic forming. He graduated from King Mongkut Institute of Technology Thonburi with a bachelor degree in Mechanical Engineering in 1993 and Master of Mechanical Engineering and PhD in Mechanical Engineering and Industrial and System Engineering from Ohio State University, USA in 2006. He is trained in the areas of Stamping and Tube and Sheet Hydroforming, especially in tool, equipment, and process design by using Advanced Finite Element Technique at CP-Forming Centre (formerly ERC/NSM) at The Ohio State University, USA under the supervision of Professor Taylan Altan. He has successfully developed warm tube hydroforming system to hydroform lightweight alloys such as Aluminium and Magnesium Alloys at elevated temperature He also developed hydraulic bulge test used to evaluate quality and property of tubular materials. Incidentally, the Hydraulic Bulge Test has been used by US and German companies and institutes. He has published more than 5 papers and 15 conference papers.
