Choose from 18+ finishing options to enhance the appearance, durability, and performance of your CNC-machined parts. From anodizing to powder coating—delivered with precision.
Every machined part has a job to do—and the right surface finish ensures it performs. Whether you need corrosion resistance for aerospace hardware, a cosmetic finish for a consumer product, or tight-tolerance plating for semiconductor tooling, DEK manages the entire finishing process in-house or through vetted partners.
We match the optimal finish to your material, application, and budget—so you get exactly the performance you need without over-engineering or overspending.
Anodizing, powder coat, PVD, DLC and more
Nickel, zinc, electroless nickel & chrome
Blasting, polishing, grinding & tumbling
Heat treating, passivation & chemical conversion
18+ finishing processes tailored to your material, performance requirements, and visual standards.
A raw machined part is rarely the final product. The right finish transforms a component from functional to field-ready.
Surface treatments like anodizing, plating, and passivation create protective barriers against corrosion, oxidation, and chemical exposure—dramatically extending service life in harsh environments.
From mirror-polished stainless steel to color-matched anodized aluminum, the right finish communicates quality and builds confidence in end-user products and OEM assemblies.
Coatings like DLC and PVD reduce friction, improve hardness, and enhance wear resistance—critical for high-performance mechanical, aerospace, and medical applications.
Every finish involves trade-offs. Here's how to think about the three key dimensions when selecting a surface treatment.
If visual quality is a priority—for consumer products, enclosures, or branded hardware—consider finishes that offer color variety, gloss control, and texture uniformity. Anodizing provides vibrant color options for aluminum. Powder coating offers the widest color palette across metals. Polishing and vapor smoothing deliver high-gloss reflective surfaces.
