Mechanical finishing is a type of finishing that protects metal parts through sacrificial metallic coating on metal component. The most common metal elements that use this type of finishing are steel and copper. Mechanical finishing works by using a combination of chemical reactions and kinetic forces to adhere the metal surface to the part.
The benefits of mechanical finishing includes a range of colors, salt spray hours, torque tension tolerances and many other specific industry needs. Mechanical plating does not produce Hydrogen Embrittlement and does not require a post bake cycle.
DiFruscia Industries utilizes its blasting options to meet pretreatment and texture requirement for various finishes. The process works on a number of surfaces and it is a fast and efficient method to prepare old materials for re-usual.
Shot peening is the process of bombarding the surface of a metal component with small spherical media called shot. During the shot peening process, each piece of shot that strikes the component acts as a tiny peening hammer, creating a small indentation or dimple on the surface. To create the dimple, the surface of the material must yield in tension. Below the surface, the material tries to restore its original shape, thereby producing below the dimple, a hemisphere of cold-worked material highly stressed in compression.
Deburring is the process of removing sharp burrs to smooth both large and small part edges. Deburring components allows for these components to be safely handled and functional. We utilize both vibratory and tumble deburring processes. Vibratory and tumble deburring are mass finishing processes in which parts to be finished are placed in a vibratory machine, usually with abrasive media, water and compound. Action or movement of the machine causes the media to press and rub against part surfaces, edges and corners to alter surface characteristics. The compound emulsifies the soils and carries them away from the parts.
