Tooling and Machining
The components were manufactured using gravity die casting technique. Special treatment was required for the center hole to make provision for a metal bush insert. The challenging task was accomplished by developing a special die ensuring the required metal pour during the casting process. The component was machined on a CNC turning machine after which a zero porosity was achieved which was critical for the customer’s requirement.
