Our range of Electric Shear is specifically designed to cut multilayered Aramide, Glass Fiber and other heavy-weight materials. Heavy Duty Electric Shear operates on the principle of conventional hand shear in which the cutting effect is produced by the up and down movement of the upper blade, the edge of which is in constant contact with the edge of the fixed lower blade. The principle employed in the Heavy Duty Electric Metal Shear has the advantage over rotary blade scissor because in that there is no bare shafts for threads to catch and wind up to eventually block the machine.
