YLJ-40TA-PE is an electric lab press up to 45 metric tons to prepare the compound ceramic or powder metallurgical sample. The electric hydraulic pump is separated from the pressing machine, which makes maintenance and replacement at easy. The pump's pressure is 30 segments programmable for pressure and dwell time. One KF40 feedthrough is installed with the high-pressure pipe, which allows customers to use the press inside the glovebox. Specifications: Motorized Hydraulic Pump Input Voltage:208-240VAC, 50/60Hz (110V version is available via 500W transformer) Output Power: 150W 180 W AC motor Built-in digital pressure controller, which is 30 segments programmable to set up multi-pressure and dwell time during raising pressure. (Pressure settings have to be monotonically increasing. Multi-step pressure relief is not allowed.) A one-pump speed controller is built to adjust the pump speed KF40 feed-through can be installed on the pipe, which allows the pipe is inserted into a glovebox and connected to the press machine. The feedthrough is not included in the standard package and can be ordered at an extra cost. RS-485 port is built on the control panel for PC operation. PC software based on LabVIEW is available upon request at an extra cost. ( You must inform us in advance if you need PC operation, and we suggest you buy a laptop from us for pre-test ) An optional touch-screen electric pump An electric hydraulic pump with a touch-screen controller is available upon request at an extra cost. It can set all parameters, such as the inner diameter of the pressing die, target pressure, and pressing time, and then the user can touch the button to go.

Small particles may slip into the gap between the pushing rod and steel sleeve and cause damage to the sleeve. You must clean the die very carefully after each use. Please consider using the 3'' Dia. Sieve Set No.200&450 Mesh to separate the 32~75 micron particles from the powder clumps. Please clean the mold with ethanol after the completion of each experiment Do not raise the bottom cylinder (piston) more than its maximum traveling distance (25 mm) The press can be put in a glovebox Warning: Customers must always wear protective goggles during operation !!!
