Material Notes:

Thixomolding® is a fabrication technique, similar to injection molding, that uses magnesium alloys as the “resin” instead of plastic. Solid magnesium alloy pellets are fed into the machine, heated to high temperatures and injected into a closed die / mold. Parts from the machine usually need no additional machining, finishing or puttying.Information provided by Parkway Products.
