Strength and stability-worthy attributes in nearly every application, and certainly so when it comes to transfer systems feeding heavy blanks of high-strength steel. When the Saline, MI, facility of a contract automotive stamper embarked on a campaign to increase its ability to provide transfer stampings to the industry, in mid-2003, it knew it needed a strong and stable transfer to maximize production speed. When it selected an 800-ton Clearing-Niagara press (132- by 60-in. bed) for the transfer-system retrofit, only a transfer system that would not limit press speed would fit the bill. At the time, management knew well that its through-the-window transfer system, already running on the firm's other 800-ton press, performed fine on lighter-weight jobs, but tended to become unstable-transfer bars vibrated and sagged- at higher press speeds and loads. So a front-to-back transfer system-with transfer supported in the center rather than the ends-stepped up to the front of the class.
