15T Compact Hydraulic Pellet Press for use in Glove-box - YLJ-15L

3.8/5 rating (6 votes)


YLJ-15L is a high-quality compact manual hydraulic press, which is capable of generating up to 15 metric tons designed for preparing compound ceramic samples in materials/chemistry research laboratories. The press has a built-in hydraulic pump with an auto-return function for quick die removal & sample retrieval. The lightweight and fully airtight design make it extremely well-suited for operation inside of a glove box where having an inert environment is crucial to prevent unwanted sample contamination. The pressing machine is made in Europe and there are two types of height that can be chosen, which is suitable put in the glovebox through Airlock Chamber. SPECIFICATIONS:
Max Pressure 
  • Normal operating pressure force: 7 metric tons
  • Max. operating pressure force: 15 metric tons with > 50 mm H Die (for < 5 minutes pressure holding)
  • The pressure gauge is built-in
Pressure Gauge
Gauge Displayed Pressure Value (Bar)  100  200  300    391
Actual Force Applied on the Hydraulic Cylinder (Ton)  3.8       7.6        11.5   15   
  • Gauge displays force in both PSI and Bar units for versatility (click picture on the left to enlarge)
  • Please follow the Force Conversion table above to obtain the equivalent force applied on the Hydraulic Cylinder according to the pressure gauge
  • Notice: Please close the Release Lever before transporting the press into the glovebox via the air-lock chamber. It will cause oil leakage if transported with the lever open
  • For calculating the actual pressure applied on your working piece, please follow the equation below:
    F = P_(Gauge Displayed Pressure Value (GDPV)) × S_(Cross-section area of the inside piston)
    Since 1 Bar = 1.0197 kg/(cm)^2, Diameter of piston is 7cm
    Assume Gauge Displayed Pressure Value is 100
    F = 101.97 × π × (D/2)^2 = 3922.78 kg Force ≈ 3.9 Ton force
    Therefore, From pressure gauge value to actual force is 26.31
    Assume the Diameter of your Die is 4 cm, and Gauge Displayed Pressure Value is also 100 Bar
    Then, the actual pressure on your working piece is:
    P_(actual on the working piece) = F/S_(Cross-section area of the working piece)
    P_(actual on working piece) = (3.9 Ton)/(12.56 (cm)^2 ) = 310 Bar
    In general: P_(actual on the working piece ) = (P_( GDPV)/26.31) / (π*r_(Crosection area of the working piece)^2)
