Below is a list of Vibratory Finishing manufacturers from Montreal, Quebec. Vibratory finishing uses the process of vibration within a barrel or drum-like enclosure to create friction between deburring media and machined parts requiring finishing. Machining, forging, engraving and extrusion often leave sharp edges, burrs, notches or protruding surface defects on machined parts which interferes with the smooth operation and function of the part, possibly causing injuries or production delays. Burrs can cause further problems such as areas of stress or weakness, shortened fatigue life or decreased fracture resistance that can cause heavy loss in terms of money and material to a manufacturer.
