OIL REMOVAL METHOD, BONDING METHOD, ASSEMBLY DEVICE, AND ATMOSPHERIC-PRESSURE PLASMA DEVICE

An object of the present invention is to provide a technique capable of removing oil regardless of a shape of a target object to which the oil is attached. Cutting oil is decomposed by irradiating the cutting oil with a plasma gas containing oxygen plasma. Oxygen radicals decompose a carbon element and a hydrogen element constituting the oil into carbon dioxide and water, respectively, to remove the oil. Therefore, paraffin and ester contained in the cutting oil can be decomposed by irradiating the cutting oil with the plasma gas containing oxygen plasma. Since the plasma gas can flow along a shape of a target object, the oil can be removed regardless of a shape of a portion of the target object to which the oil is attached.

Blended fiber mat formation for structural applications

A process and system are provided for introducing a blend of chopped and dispersed fibers on an automated production line amenable for inclusion in molding compositions as a blended fiber mat for structural applications. The blend of fibers are simultaneously supplied to an automated cutting machine illustratively including a rotary blade chopper disposed above a vortex supporting chamber.
