Metal Pickling & Oiling Services

MIP, Inc. offers pickling & oiling services on a wide variety of parts for various industries.

Pickling is the removal of oxides from the surface of metals by converting them to soluble compounds. The removal of oxides from the surface of metal sheets is pivotal to process them for extrusion, rolling, painting, galvanizing or plating. Acid treatment is a process in which the base metal is subjected to mild, moderate, or aggressive etching. The pH value of the solution is generally below 2. This process helps to dissolve oxides produced from the machining and manufacturing processes. The acid cleaning also removes scale and rust.

The metal plate that undergoes acid pickling will oxidize (rust) when exposed to atmospheric conditions of moderately high humidity. As a result, a thin film of oil or similar waterproof coating is applied to create a barrier against moisture in the air. This oil film must be removed for fabrication, plating or painting processes
