Die Casting is a process whereby liquid metal is forced into the cavity of a mold. The negative-form mold (the die) is made of alloy steel (usually Chromium steel), chosen for its ability to withstand the molten metal’s heat.
Logical option for:
Each of the above methods has its own specific advantages particularly with regard to low-porosity potential, small grain size, and minimal waste.
Gravity: Produces the highest quality structure with decreased grain size.
Low-pressure: Provides the better surface finish and approaches high-pressure’s very thin wall-thickness capabilities.
US Casting does not charge extra for storing production dies between runs, therefore this is not a factor in pricing of repeat orders.

|Additional Tolerance for every 25mm/.984252 inches||0.1||0.3||–|
For regular dimensions tolerance should be double with all parameters.
US Castings’ engineering department is available to consult on geometric complexity, surface finish, cost and other factors. US Castings’ expertise in Value-Engineering will help to achieve the desired result at the lowest possible unit or overall cost.
