Metal Finishing and Chemical Processing

Metal finishing is the process of changing the surface of an object, for the purpose of improving its appearance and/or durability. This can be accomplished through mechanical finishing & various chemical processing methods, which allows a surface to be altered so that it can achieve certain properties and meet the desired specifications of the end user. 

Arrow Cryogenics provides full-service chemical processing of metal parts and components. Our processing services can be used to improve corrosion and wear resistance, to prepare medical devices for implantation, to improve metal-to-rubber bonding, and for various other performance enhancements. 

Contact us for more information regarding our metal finishing processes and all our chemical processing techniques for your specific project needs. Call us at 763-780-3367 and we will be happy to answer your metal finishing and chemical processng questions. We are an industry leading metal finishing company.

Why is Metal Finishing Necessary?

Metal finishing through chemical processing is extremely important since it expands the lifespan of metals by providing enhanced protection against corrosion and other unwanted characteristics that can develop over time. Metal finishing can be used to improve the following qualities of the metal: 

  • Appearance
  • Adhesion (wettability)
  • Solderability
  • Corrosion resistance
  • Tarnish resistance
  • Chemical resistance
  • Hardness
  • Modify electrical conductivity
  • Remove surface flaws
  • Control surface friction 

Metal & Chemical Processing Surface Finishes

Metal finishing comprises several types of processes that are practiced by most industries which manufacture metal parts. Typically, manufacturers perform the finishing after a metal part has been formed. Metal finishing can encompass any operation that alters the surface of a workpiece to achieve a certain property. We offer a variety of chemical processing services for your part and component needs, some of which include:

Aluminum Anodizing 

Aluminum anodizing is a controlled electrochemical type of chemical processing that increases the thickness of the oxide layers that naturally exist on aluminum surfaces, improving corrosion resistance. Anodized coatings also provide better adhesion for paint primers and glues, and can be used for numerous aesthetic purposes as well. 

Hard Coat Aluminum Anodizing 

Aluminum hard coat anodizing is like standard anodizing in that both are controlled electrochemical types of chemical processing. The key difference is that hard coat anodizing provides a surface that is more wear resistant and has a smoother and harder surface than standard anodizing. While aluminum naturally forms oxide on the surface over time, the aluminum oxide that is formed on the surface during the hardcoat anodizing process is more uniform, dense, and much harder than with natural oxidation.

Chromate Conversion Coating

Chromate conversion coating is a chemical immersion type of chemical processing used by Arrow Cryogenics to passivate aluminum. This low-cost process is primarily used as a corrosion inhibitor and as a primer for paint, lacquer, or rubber bonding.

Stainless Steel Passivation 

Stainless steel passivation is a chemical process that makes stainless steel even less susceptible to corrosive environmental factors, such as air and water. While stainless steel is corrosion-resistant by nature, it is not entirely impervious to rusting. Iron embedded in the surface during part forming and machining can corrode and create rust spots on the stainless steel, called rouging. In stainless steel passivation, exogenous iron and/or iron compounds are removed from a stainless steel surface. 

Stainless Steel Electropolishing

Stainless steel electropolishing (or stainless steel polishing) is a “reverse plating” type of chemical processing. It uses a combination of rectified current and a blended chemical electrolyte bath to remove imperfections from the surface of metal parts and provide a surface that is clean and bright. Electropolishing is an effective replacement for more traditional mechanical finishing techniques.

In-House Metal Finishing & Chemical Processes

At Arrow Cryogenics, all our chemical processing services are performed entirely in-house. The parameters of our chemical processing techniques are adjusted to meet our customers’ exact specifications. We also offer testing to verify quality after processing. 

Additionally, we can provide cleaning services to remove contaminants from parts prior to chemical processing. 

NADCAP Certified for Metal Finishing

Arrow Cryogenics is Nadcap certified for chemical processing and is in compliance with the AC7004 Aerospace Quality System for the Aerospace and Defense Industry. As part of Nadcap accreditation, our processes were audited based on stringent industry guidelines and are regularly reviewed to maintain compliance.
