Detroit DEGREASING WASHING CLEANING
Degreasing Washing Detroit is commonly utilized to remove contaminants on the surfaces of metal prior to applying a coating. The metal stamping process leaves residues, such as lubricants, metal shavings, and dust, on the stamped parts as they come out of the stamping presses. These contaminants could eventually affect the part’s function, so they must be eliminated before the parts can be sent for secondary operations such as metal finishing or welding or directly to the manufacturing line.
Automotive Tumbling provides a wide range of Degreasing Washing Detroit services. Several of our clients call upon us to perform highly specialized cleaning services to meet there demanding needs. In addition, so parts require more than one cleaning process may be required, both after stamping and again after Detroit metal finishing to guarantee its optimal function.
One of the most important steps in the metal forming process is the preparation of the formed metal part for a finishing operation. Whether the part is to be plated, painted, chromated, or e-coated the quality of the final finish depends on the effort applied to achieve a proper cleaning that is compatible with the finishing process. Many of our automotive manufacturer clients have implemented special programs to test the effectiveness of the cleaning method for the stamped parts, both after cleaning and after the part has been welded, primed, and painted.
Metal Stampings Cleaning Options
Two of the most commonly utilized cleaning processes for metal stampings are degreasing and passivation. In addition, the cleaning processes that involve the removal of metal from the part, such as electropolishing and deburring.
Aqueous and Vapor Degreasing
The two major degreasing processes for metal stampings are aqueous and vapor degreasing.
- Aqueous degreasing can be done by either in-line spray or by immersing the parts in an acidic or alkaline water-based cleaner to remove stamping fluid. Ultrasonics may be used in immersion to aid in removing residues.
- Vapor degreasing involves placing cold parts in the degreaser to be steamed by solvent vapors that condense on the part and dissolve oil and other contaminants. The parts are heated until condensation stops and the solvent drains off. Other options in vapor degreasing are to immerse the part and add rotation or use Ultrasonics for smaller complex or fragile components.
Benefits
Degreasing operations have become more environmentally friendly, as less toxic solvents can be used and the run-off oils can be distilled and processed. Vapor degreasing is compatible with many metals, including stainless steel, galvanized steel, aluminum, copper and bronze. Vapor degreasing is suitable for more fragile stampings that cannot be tumbled or those that require a more intensive cleaning method, such as medical device parts. Aqueous degreasing is appropriate for parts that have been stamped with water-soluble lubricants.
Passivation
Passivation involves immersing the stamped metal parts into a nitric or citric acid bath to remove free iron and other contaminants that may have been introduced during the stamping process. The treated part, which is rinsed and dried following the acid bath, forms a chromium oxide film that resists rust and corrosion and can enhance sterilization. Passivation does not change the appearance of the part.
Benefits
Passivation is suitable for high volumes of parts that require rust resistance, but does not provide the same smooth appearance or level of corrosion resistance as the more expensive electropolishing. It is primarily used for stainless steel parts, although titanium and other metals may undergo passivation. However, some metals, such as aluminum, copper, and carbon steel, cannot withstand certain acids.
