Die casting is a manufacturing process widely used in the production of metal parts. It is a process that involves forcing molten metal into a mold cavity under high pressure. The mold cavity is created using two hardened tool steel dies that have been machined into shape. Die casting is known for its ability to produce high-quality and complex ...

When calculating pressure die casting tonnage, the process is typically done in two steps. First, the die material is selected. Tool steel is the most common metal used in dies. The tool steel used for dies is typically high-grade and has a 100 to one-hundred-hundred-thousand-five-thousand-hundred-hundred-hundreds of cycles.
Labor cost and Post-Processing Cost. Labor costs, including deburring, quality inspection, packaging, etc., account for about 1.5% of the cost of die-casting blanks. 1 Kg die casting parts labor cost= die casting blank cost (material cost 4.3 USD+die casting machine cost 1 USD) x 1.5%=0.08 USD.

This document discusses how to calculate the machine tonnage required for high-pressure die casting parts. It explains that the tonnage is based on three factors: die clamping force, fill ratio, and mold size. It provides detailed steps to calculate the die clamping force by determining the separating force using the specific injection pressure and total projected …
This paper investigates the critical plunger velocity in high-pressure die casting during the slow phase of the piston motion and how it can be determined with computational fluid dynamics (CFD) in open source software. The melt-air system is modelled via an Eulerian volume-of-fluid approach, treating the air as a compressible …
To accurately describe and analyze the energy efficiency level of the die casting workshop, the energy score with different levels (die casting unit level, production line level, and workshop level) is calculated as (15) u …

sand casting process. The molten metal in die casting can be regarded as Newtonian fluid; therefore, to model the fluid flow in die castings, the complete Navier-Stokes equations …
5. Choose the place where the liquid metal flows into the cavity without vortex and exhausts smoothly; The gate position should be conducive to the elimination of gas in the mold cavity. In production practice, it is very difficult to eliminate all the gas, but it is a problem that should be considered in the design to eliminate more gas ...

Second, few studies have discussed two emerging technologies used in the vehicle industry: high-vacuum die casting (HVDC) and semi-solid die casting (SSDC). HVDC was introduced to reduce gas entrapment during die filling (a harmful phenomenon, which generally leads to various casting defects) and can produce higher performance …
