Category HPDC casting process

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...

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.
