Place the powder into the insulated mold die equipped with four-point probe contact pins. (2) \u003cstrong\u003eProgram Test Profile\u003c\/strong\u003e: Select the testing protocol: multi-step pressure holding (e.g., 10 to 200 MPa in 20 MPa increments), continuous constant-speed loading, or pressure-release springback cycles. (3) \u003cstrong\u003eAutomated Execution\u003c\/strong\u003e: The motorized actuator drives the ram downwards. At each pressure step, the system holds load, applies a precision DC current, reads micro-voltages, and logs real-time sample height. (4) \u003cstrong\u003eData Curve Generation\u003c\/strong\u003e: The software plots real-time curves: Resistivity vs. Pressure, Conductivity vs. Compaction Density, and Pressure vs. Thickness (Springback).\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 1319.27px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 51.675px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 51.675px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 51.675px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eEJGAFPPRCCDT (EJG-AFPPRCCDT) \u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eAC220V\u003cspan style=\"font-size: 0.875rem;\"\u003e±10%, single phase, 50\/60Hz, ~50W\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 216.8px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 216.8px;\"\u003e\u003cem\u003eSoftware \u0026amp; Control Interface\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 216.8px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eParameters setting and status display\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHistorical testing data can be sourced and checked\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eResistivity vs. pressure curve \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eConductivity vs. pressure curve\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCompaction Density vs. pressure curve\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eTesting report generation and print\u003c\/span\u003e   \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/EJGAFPPRCCDT_03_160x160.jpg?v=1785625311\" alt=\"\" style=\"float: none;\" width=\"166\" height=\"81\"\u003e \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/EJGAFPPRCCDT_04_8823cfbe-ac83-425c-ac4f-360060ec0ba9_160x160.jpg?v=1785626614\" alt=\"\" style=\"float: none;\" width=\"180\" height=\"71\"\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 106.4px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 106.4px;\"\u003e\u003cem\u003eTesting Resistivity Range\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 106.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eResistivity: 15*10^(-6) Ω*cm ~ 200 kΩ*cm; \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eDigital Voltage Reading: 10 mV ~ 100 mV, automatic\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"font-size: 0.875rem;\"\u003eCurrent Levels: 0.1 uA, 1 uA, 10 uA, 100 uA, 1 mA, 10 mA, 100 mA, and 1 A\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 126px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 126px;\"\u003e\u003cem\u003eTesting Pressure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 126px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eStandard Applied Force: \u003cspan style=\"color: rgb(255, 42, 0);\"\u003e3000 N (300 kg force).
