[3] Squeeze casting was originally created to make stronger metal parts for use in the construction and defense industries.
[1] Together, the team of scientists devised a new way to combine extremely high temperatures and 1.035 bar (15.000 psi) of pressure to reshape molten metal.
Some problems they encountered included combining the exact temperature with the correct pressure in order to form the strongest metal.
[4] One of the greatest drawbacks that inventors of squeeze casting have encountered is the configuration of re-entrant cavities and internal passages that use the core.
Although this method seemed like a valid solution, the high temperatures from molten metal easily penetrated the core made from sand.
Moreover, through this process, a low-cost option of producing squeeze cores that is able to withstand high pressures has been made open to the public.
Created just over fifteen years ago, the process continues to get better to a point where decreasing the price of production has become a priority.
