Focus Areas

The program shall focus on the following topics:

• Basic concepts of the die-casting process
• Understanding the Cold chamber machine and PQ² (flow characteristics) of the machine
• Study of part drawing and / or 3D model and understanding the product’s end-requirement
• Basic guidelines for designing the die-casting die
• Parting line geometry
• Feed and runner system
• Thermal balancing the die
• Ejection system of the casting
• Mechanical strength requirement and fulfilment in the die design
• How to do process FMEA and build the die-design anticipating the likelihood of defects in advance
• Simulation and course correction to reduce rejection
• Case study with sharing of experience

Background

Die-casting is a metal casting process, wherein the molten metal is injected at very high pressure to produce parts with good dimensional accuracy. To cast the parts at high pressure, a die casting machine is used. This application finds uses is many areas such as Automobile, Aviation, Telecommunication, hydraulics & pneumatics parts, electrical and so on.

A few examples to mention are Two-wheeler engine crank cases, cover kick starters, cylinder head, cylinder barrel, four-wheeler Alloy wheels, 2 wheeler front and rear wheel hub, 2-wheeler carburettor, earth moving equipment hydraulic valves, 4 wheeler air brake parts, to name a few.

The die-cast die & mould design is an iterative process that determines the contour of die cast parts and affect its properties. Following a systematic design process will always lead to better outcomes. This program shall cover how to design a die-cast part suitable for high pressure die-casting, wherein guidelines are given for ensuring trouble free casting production of parts.

Keeping this in mind, IMTMA is organizing a 5 day online programme to impart training on Fundamentals of pressure die-cast parts die design.
