Brass Die-Casting Company to Take on Copper (continued) Customization is familiar to Rheocast, as most of the parts they presently manufacture are custom-tailored to client specifications. “We help our customers develop their specifications to complement the die cast process,” Morton explained. “For this project our objective will be to utilize the collective resources of the Fall River Group (Rheocast's parent company) to develop a high-tech, turnkey product of very close tolerances. The desired outcome will produce a component of even greater efficiency to optimize further the gains in the finished product. We will definitely bring all our experience and engineering capability to the task.” Morton feels cast copper heat sinks could be used in cooling electronic components, such as voltage rectifiers, or hardening large microchips for severe industrial environments or high-wattage power supplies, to name a few. “I feel potential markets may exist in the fields of industry, computer technology and transportation,” he said. Whether casting motor rotors, heat sinks or any other application that can benefit from this new process, Morton feels the impact of the copper die casting process on the die casting industry, in whole, remains to be seen. “I imagine a great deal of activity over the course of the next seven years for the die casting houses who are prepared to make the commitments required to cast copper. The impact on our industry after that point, as related to the motors campaign, will depend on whether manufacturers elect to make the component themselves or continue to outsource that activity.”
