For customers requiring coatings on parts, MicroGroup, now a part of TE Connectivity, offers a multitude of coating options.
Coatings are used for various reasons such as electrical insulation, lubricity (low friction), mold releasing and corrosion protection.
Some coatings include Parylene conformal coating, Teflon (P.T.F.E.) coating, and Alpha coating. Many thicknesses can be achieved, and many color options are available. Size of the part is usually not an issue. Parts can be masked-off to reveal only the section that needs coating. An example of this would be marker bands or rings that are intermittently placed at certain dimensions running down the length of a hypodermic needle.
Coating materials are applied using various methods, which include spraying, dipping, powder coating and vapor deposition.
