What is Gravity Die Cast (GDC) + MAP?
It is Enkei’s proprietary version of the standard GDC process combined with other processes dubbed MAP. First of all, Enkei uses A357 aluminum ingots combined with a special blended material to further increase the strength and life of the aluminum. Before being poured into the mold, the temperature is increased to xxx degrees. When pouring, Enkei uses a tilt method with precise angle and consistent rotation to decrease air bubble formation and increase overall balance. After the pouring, temperatures is decreased to xxx degrees for cooling. However, this occurs much quicker than standard casting processes allowing for a more balanced material content. Specific positioning and releasing of “pin mechanisms” enable this advanced cooling technology. Imagine sugar water and how the content between the top and bottom can easily differ. Basically, the quicker the better. The temperature is then increased back up to xxx degrees and then quickly dropped to xx degrees for the final cool off pro
