  Hydraulic presses are used in a wide range of industries to provide different functions from forging, molding, punching, deep drawing and metal forming.  Hydraulic presses generate force by supplying high pressure fluid to a hydraulic cylinder to generate the force required to perform their function. The cylinders in your hydraulic press not only control the force being produced but also the speed at which the press can move and the overall efficiency of the machine. In this blog, we’ll explore the application of cylinders for hydraulic press applications. Hydraulic Cylinders in applications The primary type of hydraulic cylinders used today in press applications control the motion by operating as single or double-acting.   Single-acting cylinders use fluid pressure to move the cylinder in one direction and use a spring or smaller secondary cylinder capable of retracting the press whereas double-acting cylinders use fluid pressure to move in both directions.    The basic component

  25CrMo4 (4130) is a heat-resistant, heat-treatable steel grade that is often used for components with high loads in motorsport, industry and in aviation. Among other things, cylinder piston rods , screws, roller shafts , roll cages, chassis components and vehicle frames are made from this. Due to its chemical composition,  25CrMo4  is suitable for hardening and has a tensile strength of over 650 N / mm² in the tempered state. 25CrMo4  is valued for its good weldability and bendability. 25CrMo4  Properties German Designation 1.7218   Specifications LN9369 / AIR9160C, TE012   Mateial Properties EN 10269, KG, 4130, G41300, J24056   Mechanical Properties     Conditions Quenched, tempered, peeled, induction hardened Q+T   Tensile Strength 600-1100 N/mm²   Chemical Composition     C: 0,22 - 0,29 %   Cr: 0,9 - 1,2 %   Mn: 0,6 - 0,9 %   Mo: 0,15 - 0,3 %   P: max. 0,025 %   S: max. 0,035 %   Si: max. 0

  SCM430 steel is a chromium-molybdenum alloy steel as per Japan Standard. JIS SCM430 steel contains a lower carbon content but provides better weldability comparing with SCM440 Steel. It is frequently applied to the gas & oil area.Typical applications include components such as valve  bodies,pumps and hydraulic cylinder rod fittings.
