Disk Friction Screw Press In Ethiopia

We are engaged in manufacturing a variety of Screw Presses, which might be used to dewater and wash secondary as well as virgin fiber. AC servo numerical control electric fly press of the present invention, mentioned AC servo numerical control electrical machine is a kind of motor that receives input signal management and do to respond quick; Its management accuracy is excessive; Operate steadily, in its rated velocity scope, can each export nominal torque, overload capability is robust; Management performance is dependable, and response quickly.

Presses in use in North America for impression die forging currently range as much as 50,000 tons; presses of 72,000 tons and eighty two,000 tons are in operation in France and Russia. The benefit of static strain kind electrical screw press is its static pressure screw-nuts and the static stress all these components are designed to be in a closed screw rotates, the nut will drive the slide block to move up and down.

Dynamic mechanical and mathematical models for screw press and plastic-working processes of die forging and coining have been developed, verified with experimental observations and used for evaluation of screw press dynamics. No consumable parts due to no friction driven system (On the machine which makes use of servomotor normally use, connecting belt between motor and flywheel wears out but its life lasts for a number of years and is cheap to procure.

The perfect known instance is a plastic injection molding machine: pellets of plastic are admitted at one finish; the barrel surrounding the screw is heated; and molted plastic discharges at the different end and is pushed into the injection molding die.

The electrical screw press requires extra electrical power, however its components wear much less, and it is particularly indicated for the production of elements that require extra strokes to be completed. In case of hydraulic press, forming is unsuccessful with out giant scale of capability and pressing time getting longer, and there are defects of fabric temperature decreasing and quick life time of software.
