Calculation of the proper amount of rubber for your product.How will you decide?Īpart from safety and ease of operations, your final choice of a compression moulding press depends on these six important considerations When the lower platen is raised or lowered in the vertical plane, you call it upstroking while in downstroking, the upper platen is the driven plate (moving up and down). One of the platens is fixed in your compression moulding press. On the other hand, the presence of ejector pins or strippers on fixed mould presses will speed up your operation. You call it charging (loading) and stripping (unloading) by hand. When you have free loose moulds, your operators need to load and unload them on a press table manually. You will see that compression moulding presses offered by most reputed manufacturers are vertical and the moulds can be heated using electric rods, steam, oil, water or other medium.ĭepending on requirement, your moulds may be fixed to both the platens or part fixed to a platen, or totally free to be drawn out. Further, you could customize your bed size say lower tonnage on a larger work area or higher tonnage on a smaller area of work. This means you can get full pressing force ( or tonnage) anywhere in the range of stroke using hydraulic press unlike a mechanical press.īy varying the ram speed and other operating parameters, you can optimize cycle time for each of your job. Hydraulic presses are preferred by your peers in the industry because they give Performance, Reliability, and Versatility. ![]() (Disclaimer: The standard industry terms above are borrowed from the website of Beckwood Hydraulic Presses and Machinery). Heated Platens: These are plates that have heating capabilities.In these cases, the power system and even the controls may be designed into a separate unit capable of being placed adjacent to the press or away from the press. Other applications may preclude the power system from being able to be installed at the top around the crown structure of the press. Remote Power Skid: Some press applications may require that the hydraulics be located remotely from the press itself.Bed Height: Bed Height is the distance from the bottom of the hydraulic press structure to the working height or top of the bed bolster.The bolsters can be machined with a variety of work holding features such as T-Slots, Drilled and Tapped Holes, Lift Rails for Quick Die Change, etc… The plate is usually bolted to the bed and rams substructures. Bolster: The removable plate that serves as the working surface for the bed and ram.This is also commonly known as the Open Height. Daylight: The distance between the bed bolster and the ram bolster when the ram is fully retracted.As standard, this dimension is usually within “0.25” due to assembly processes. This is also commonly known as the Closed Height. Shut Height: The distance between the bed bolster and the ram bolster when the ram is fully extended.Stroke is the total distance that the ram can travel, from full extension to full retraction. ![]()
