Towards lube-free aluminum high pressure die casting using duplex AlCrN physical vapor deposition coatings

Journal of Materials Research and Technology, 2023
Aluminum high pressure castings (HPDC) were successfully produced on two simple but slightly different H13 steel dies that had been coated with AlCrN physical vapor deposition (PVD) coatings and without the use of conventionally-sprayed die lubricants ...

Optimization Of Runner Design In High Pressure Die Casting (Hpdc) Die

, 2017
In order to produce high quality parts with high pressure die casting, computer aided simulation has been used to optimize mold designs. Finite difference (differential), finite volume and finite element methods have been used in the filling process simulation and significant progress has been made for general problems.

Numerical simulation of fluid flow, solidification and defects in high pressure die casting (HPDC) process

IOP Conference Series: Materials Science and Engineering, 2019
Abstract The high pressure die casting process is extensively used to manufacture light metal parts with high productivity. A major drawback of the process is the relatively high variability in mechanical properties and poor repeatability between casting cycles, limiting the achievement of weight reduction through lighter design ...
