A very effective method used to protect and improve the usability of a wide range of metal products is metal finishing. Automotive parts and firearms are just two examples of product categories that can benefit from the application of this service. A metal finishing company can employ methods such as deburring, plating, cleaning, and polishing for various types of industries including aerospace, military, medical, and automotive.
Metal Finishing Techniques
Based on the material part and the desired finish, a metal finishing company may utilize one of several types of finishing techniques. These can include:
Deburring – this technique falls under the category of vibratory finishing in which small metal parts consisting of defects such as burs on the outside of the metal surface are placed in a vibratory tumbler containing particularly shaped pellets of media. The vibrating process eliminates the burs on the outside surface of the metal as well as undesirable internal features such as holes.
Anodizing – this technique involves the application of a method referred to as electrolysis in which the metal is coated with an oxide. The process provides protection for the metal as well as enabling a decorative benefit to be realized as well of the application of a particular color of choice.
Passivation – this technique involves the application of a thin protective coating to the material which preserves and strengthens the metal part. The process involves soaking the metal in a passivating acid bath followed by neutralization and rinsing. After the part has dried, what is left is a protective outer later on the metal.
Polishing – this technique utilizes a centrifugal barrel finishing process that produces a constant and consistent finish which enhances the metal’s appearance and reveals its shine.
Additional techniques that may be offered by a metal finishing company include radiusing, deflashing, plating, and cleaning.
Choosing a Finishing Company
If you are searching for a company to handle your metal finishing requirements, make sure they can provide you with any of the above services as well as possible additional services you may need. It’s important to consult with a reliable and experienced metal finishing company regarding the finishing techniques that are best applicable to your particular project requirements.
