Giga Die Casting

Introduction:
The Giga Press is the largest die casting machine in the world to date. It can weigh up to 430 tonnes and have a clamping force of up to 61,000 KN. Additionally, these gigantic die casting machines are as big as a house and capable of casting extremely large components. Currently, IDRA and LK Group are the only ones making these machines. And Tesla happens to be the first company ever to order the Giga Press. Since then, people associated with the die casting industry are eager to see the ‘world’s largest die casting machine’ in action.

History:
The name ‘Giga Press’ was first coined by Riccardo Ferrario, the IDRA Group’s general manager. The IDRA group introduced the Giga Press in late 2018. It has been in their catalog since then...

Biscuit Thickness Validation (HPDC)

Abstract: This time I have found one more solution for biscuit thickness validation in high pressure die casting. In this paper we will discuss, what is biscuit thickness?, why we need to identify right biscuit thickness?, how we can validate right biscuit thickness? and effect of biscuit thickness variation. This paper is all about to clear all myth to calculate biscuit thickness in high pressure die casting. This is very serious business when we are calculating biscuit thickness to avoid casting defect. Through this paper I would like to share this knowledge and I hope it will helpful to others. “Keep learning till death “.

Keywords: (Biscuit thickness, plunger, hpdc, die casting, casting defect, solidification)

I. INTRODUCTION
Biscuit thickness ! is a thickness of initial runner wh...

Methodology of Die Design for HPDC

Abstract: HPDC die design is a very easy game, yes you can cast your casting as you desire. This can only happened when you can design casting feeding system scientifically, with the help of fluid mechanics principle, you should understand the thermal balancing of metal flow system, you should understand flow path of solidification. Your expertise require to maintain volume to surface area ratio in decreasing order from diffuser to casting filling end point...

Hidden Parameter High Pressure Die Casting

Abstract: Casting manufacturing from LPDC, GDC and HPDC process show some defect or you can say some variation in defect quantity. For supplying quality product to customer these defect variation must be reduced. In this work we try to make logical relation between hidden parameter and defect variation. Current problem is that we set all process parameter and run die than validate with minimum defect %. But problem will come after bulk production, we found overall 15-20% rejection. Even after strong validation of machine and die parameter.

Key Words: die casting, rejection variation, pour, ladle, shot sleeve, temperature, filling time, heat loss, plunger high speed.

1. INTRODUCTION
We are at steady die casting solutions work to make best die casting process...
