At Pentagon EMS, exceptional parts deserve exceptional finishes. Through the combined capabilities of Pentagon EMS, the StenTech Precision Parts Division, and AME, we offer a comprehensive range of coating, plating, polishing, and surface treatment solutions that improve durability, corrosion resistance, conductivity, wear performance, and appearance.
Our engineers recommend the ideal finish based on your application, material, and operating environment. Whether enhancing precision-machined components or chemically etched and laser-cut parts, every finishing process is selected to maximize performance, extend service life, and ensure consistent quality.
Available finishes include electropolishing, anodizing, passivation, bright nickel, nickel sulfamate, bright tin, matte tin, black zinc, gold plating, powder coating, tumble deburring, and other application-specific surface treatments—delivering components that not only meet specification but perform reliably in the most demanding environments.
Electro polishing is an electrochemical process that removes a thin layer of material from the surface of a metal part, leaving it exceptionally smooth, clean, and corrosion-resistant. By using an electric current in a chemical bath, microscopic peaks on the metal surface are dissolved, reducing roughness and creating a bright, reflective finish.
The process not only enhances appearance but also improves performance by reducing friction, eliminating burrs, and preventing contaminants from adhering to the surface. At StenTech Parts, electro polishing is one of the many finishing options we offer to ensure your components meet the highest standards of quality, reliability, and durability.
Anodization is an electrochemical process that transforms the surface of aluminum and other metals into a durable, corrosion-resistant oxide layer. This controlled oxidation not only strengthens the surface but also enhances wear resistance and provides an ideal base for dyes or additional coatings. The result is a finish that improves both performance and appearance while maintaining the metal’s natural properties.
At StenTech Parts, anodization is one of the key finishing processes we offer, delivering components that are tougher, longer-lasting, and tailored to the specific needs of your application.
Gold plating is the process of depositing a thin layer of gold onto the surface of a metal part to enhance conductivity, prevent oxidation, and improve overall durability. Known for its excellent resistance to tarnish and corrosion, gold plating is widely used in applications where reliability and signal integrity are critical, such as electronics, medical devices, and aerospace components.
Although more expensive than many other finishes, gold plating delivers unmatched benefits where performance cannot be compromised. At StenTech Parts, we provide gold plating as part of our comprehensive finishing options, ensuring your parts not only perform at the highest level but also maintain long-term stability in demanding environments.
Coming soon to StenTech Parts, Physical Vapor Deposition (PVD) is a cutting-edge process that deposits thin, durable coatings onto metal surfaces in a vacuum environment. These coatings enhance wear resistance, reduce friction, and improve overall performance without altering the part’s core properties.
StenTech already holds the exclusive process for SMT stencil coating, setting the industry standard with our BluPrint™ PVD technology. Now, we are developing specialized PVD coatings for parts, bringing the same breakthrough durability, consistency, and performance benefits to precision components across industries. This innovation will allow us to deliver parts that not only meet your specifications but also last longer and perform better in demanding environments.
Bright nickel plating is a versatile finish that combines durability, corrosion resistance, and a smooth, reflective appearance. The process deposits a uniform layer of nickel onto the surface of a part, creating a hard, protective barrier that enhances wear resistance while also delivering a bright, decorative finish.
At StenTech Parts, bright nickel is a trusted option for customers who need both performance and appearance, ideal for applications where strength, conductivity, and an attractive finish are equally important.
Every project at Pentagon-EMS (StenTech) is custom-engineered to your exact requirements. Because no two projects are alike, our streamlined quote process helps move you from concept to production quickly, accurately, and with confidence.
