Technical Resources
Compare metals, polymers, finishes, and protective treatments by appearance, durability, environment, geometry, and production requirements.
Start here
Material choice feels large because it is really three smaller choices stacked together. Separate them and the options fall into order. Decide what the part is made of, then what its surface becomes, then what keeps it
01
Substrate
What it is made of. Sets weight, strength, cost, and how the part ages before anything touches its surface.
02
Finish
What the surface becomes. Sets appearance and feel, from a matte grain to a mirror face to color grown into the metal.
03
Protection
Defines what the surface must withstand and whether added protection is required to hold up where the part is installed.
These are three decisions, but not always three separate operations. Some processes provide both the finish and the protection in one step.
You do not have to know the answers yet. The rest of this page walks each layer in the same order.
LAYER ONE · THE SUBSTRATE
Molds into rigid three dimensional parts at volume, so bezels, covers, and housings come out dimensionally consistent and ready to finish.
Impact resistant and optically clear, so a polycarbonate graphic overlay or bezel stays readable and intact under repeated handling and pressure.
Flexible and print stable, so a polyester overlay conforms to gentle curves and withstands repeated flexing and cleaning when properly specified.
THE MATERIALS, UP CLOSE
Each material family is shown at the same crop, lighting, and background so the differences below are the differences you can see.
LAYER TWO · THE FINISH
The finish determines how the part looks and feels. It comes down to two decisions: how the material itself is treated, and how color, graphics, or markings are applied.
Forms a controlled oxide layer on aluminum that can remain clear or accept color. Because it becomes part of the surface, it generally resists chipping better than an applied coating, although it can still scratch or wear.
Creates a directional or softly diffused finish that reduces glare and makes routine handling marks less visible than they would be on a mirror finish.
Refines the metal to a bright, reflective surface. It creates a premium appearance, but fingerprints and fine scratches are more visible.
Removes selected areas of the finish to expose bright metal. It is commonly used on raised logos, borders, or bevels to create sharp contrast against a darker field.
Deposits a thin layer of metal such as nickel, chrome, gold, or brass over a compatible substrate. It changes the appearance and can add selected surface properties, but it does not give the part every property of solid plated metal.
Adds opaque color over the substrate. Liquid paint supports precise color and detailed decoration, while powder coating creates a thicker, more robust film generally better suited to larger panels and components.
Applies controlled ink layers for repeatable logos, symbols, text, and spot color. Durability depends on the ink system, substrate, operating environment, and any protective layer.
Places color into recessed or bounded areas so etched, cast, or stamped graphics read with strong contrast. The recess helps protect the color from direct surface wear.
Prints graphics on the back of a clear polycarbonate or polyester face so the material itself protects the artwork from handling and abrasion.
Laser marking changes the surface, while engraving removes material. Both support durable serial numbers, variable data, and line work without relying on surface ink.
SURFACE FINISHES, UP CLOSE
Each finish is shown up close so you can compare how surface treatment changes color, texture, reflectivity, and visual depth.
Layer three · The protection
Protection defines what the surface must withstand and whether added protection is needed. Some parts need none. Others fade or wear without it.
Clear Coat and Lacquer
Seals the finished surface, so color and print resist handling and light abrasion in normal indoor use.
Hardcoat Anodize
Improves wear and abrasion resistance. Corrosion performance still depends on alloy and sealing.
Raises a clear dome over the graphic, so a printed badge gains depth and a sealed, wipeable surface.
Overlaminate
Bonds a clear film over a printed overlay, so graphics on a control panel resist chemicals, cleaning, and abrasion.
UV-Resistant Coating
Slows fading and surface breakdown so outdoor color and graphics hold their appearance longer.
Some processes, including hardcoat anodizing, create the appearance and improve protection in the same operation. The three decisions stay conceptually separate even when one step satisfies more than one of them.
Why the same color looks different
The substrate and finishing process affect color appearance, reference matching, and service performance. Defining the color route early prevents first article surprises.
Anodized color forms within the surface
It resists chipping, but its range is narrower than paint and cannot hit every brand tone exactly.
Plated color comes from the deposited metal
Chrome, gold, and brass tones come from the plating itself, not from a printed color.
Printed and painted color offers the widest range
Screen printing and paint reach tones anodizing cannot, at the cost of a surface layer that needs protection.
Use a reference, not an adjective
A Pantone number, an approved sample, or a signed drawdown removes the guesswork that "dark navy" leaves open.
Once the material is chosen, the exact color reference is recorded on the drawing. See Design Drawing Requirements.
One reference, four routes
Anodized
Screen printed
Painted / Enamel
Plated Tone
The same reference color through four routes. Substrate, finish, gloss, texture, and process shift how it reads, which is why an approved sample settles color better than a name.
How to choose
The environment eliminates the most options, so decide it first. Form, appearance, durability, and budget narrow what remains. Six questions guide buyers to the right material.
Environment
Indoor or outdoor, sun, chemicals, cleaning, abrasion, heat, and moisture. Each rules out finishes that cannot survive it, so naming the environment shortens the list before anything else.
Form and Construction
Is the part flat, formed, sculpted, flexible, or rigid? The required form narrows the compatible materials and finishes before appearance is considered. The Manufacturing Methods guide covers how each form is built.
Appearance and Color
Warm or cool tone, matte or mirror, metallic or painted color, flat or dimensional. This sets which finishes fit the look you want.
Durability and Service Life
How long the appearance has to last. A part that must look new in ten years narrows to finishes and protection that hold, not the cheapest that ships.
Mounting and Weight
What the part attaches to and how much weight the surface can carry decides between a solid cast metal and a light printed overlay.
Budget and Volume
Cost and quantity set which finishes and tooling make sense, so the right choice at 500 pieces is not always the right one at 50,000.
You do not need to weigh all six alone. Send us the part and its environment and we narrow it with you.
The full picture
Material defines the substrate. Manufacturing method defines how the part is formed. The production drawing records the approved combination.
How it is built→Manufacturing Methods
Not every material runs every process. The methods guide shows which constructions fit, and confirms what is buildable.
What is compatible→Compatibility Matrix
Material and method together decide feasibility, so both axes sit in one place on the methods guide.
What gets recorded→Design Drawing Requirements
The material, finish, and color you choose are documented on the drawing, so the first order and every reorder run from the same reference.
This page helps you understand and narrow. The matrix confirms what is buildable. The drawing records the final decision.
When in doubt
A screen cannot fully reproduce grain direction, gloss, texture, depth, or the visual weight of a metallic finish. When appearance is critical, the approved physical sample becomes the production reference and the standard future orders are measured against.
See the Sample & Approval ProcessBadges, nameplates, labels, overlays, trim, faceplates, and functional components place different demands on material and finish. The right combination depends on the part, its environment, appearance, and service requirements.
