Aristo Cast Handles Tight Turnaround for Trophy Order
Mich. The investment casting firm had completed a number of projects for students, including last year’s donation of muffler caps and wheels to the school’s annual automotive design competition.

exactly what the investment cast- ing process can achieve, not only in detail but in a short amount of time,” Ziemba said.
