PAS5000 Melt Quality Control System


The Palmer PAS5000 represents a breakthrough in hydrogen porosity control of the aluminum melt and castings. With precise computerized control of the vacuum setting and quick automated measurements of sample density, the long-standing problem of operator variation is virtually eliminated. The setting parameter inputs are located on a password protected HMI screen to be set by quality or engineering, while the test screens guide the operator through each action making on-floor operation of the unit simple, quick, and accurate ensuring the tests are run correctly each and every time. The PAS5000 is the only system on the market with the ability to perform and report RPT sample density, % Porosity, and Density Index all in one machine. Test results are stored by date/time, vacuum setting, and alloy along with company information, such as furnace number and part number. Data can be directly exported to a SCADA system or retrieved through either the easy access USB port or ethernet port. In addition, a built-in strip printer allows for the results to be printed and attached to a traveler or quality paperwork.

Designed by Foundry Engineers, the PAS5000 is built tough for daily foundry floor operation while meeting the most stringent quality system requirements of the end customer.
