Evaluate of Chill Vent Performance for High Pressure Die-Casting Production and Simulation of Motorcycle Fuel Caps

MATEC Web of Conferences, 2017
Inappropriate air vent design always induced porosities in thin and complex shape of high pressure die-casting (HPDC) products. Chill block installation was preferred to improve permanent molds for reducing porosities. There were not regular to obtain an

A new approach to enhance the efficiency of local squeezing during high pressure die casting of aluminum alloys

Materials & Design
High Pressure Die Casting (HPDC) produces near-net-shape components with varying wall thicknesses, leading to heterogeneous solidification conditions. These effects led to inhomogeneities, which significantly affect mechanical properties. Local squeezing
