Popular Finishes for Metal
Part is cleaned and deburred. No surface finishes are applied.
Type II anodize provides increased corrosion resistance and can be used as a base for paint and other finishes. Thickness ranges from .0002”-.0012”. Will conform to MIL-A-8625 Type II, Class 2. MIL-A-8625.
Color anodizing involves using dyes to affect the part’s surface color. Anodized colors cannot be matched to specific Pantone or RAL colors. Type II coatings are susceptible to wear and may bleach or fade under prolonged direct sunlight.
Type III hardcoat anodize produces a thicker layer of standard anodizing, making it more durable and wear-resistant. It can be used as a base for paint and other finishes. Colors tend to come out slightly dark due to thickness. Anodized colors cannot be matched to specific Pantone or RAL colors. Thickness is generally 0.002” and will conform to MIL-A-8625, Type III, Class 1/2.
Although unpigmented, a clear hardcoat anodize finish will darken the part surface due to the higher thickness of the coating compared to standard anodizing. Depending on various factors, the natural color can vary from light to darker gray or brown.
Chromate conversion coatings, also known as chem-film, enhance corrosion resistance and conductivity properties and can be used as a base for paint. Chem-film coatings add very little thickness, about 0.00001”-0.00004”. Chem-film will conform to MIL-DTL-5541, TYPE I/II CLASS 1A or CLASS 3 as specified. If other specifications, such as MIL-DTL-81706, are required, they should be specified in a supplied drawing.
Type I chromate conversion coatings contain hexavalent chromium, which causes the coating to appear gold or brown in color typically. Type II lacks hexavalent chromium, thus the coating will appear clear and not affect surface coloration.
Provides a continuous, protective color finish on parts using evenly applied, heat-cured paint. Thickness is usually .006”-.012” and conforms to ASTM D7803 and various MIL and FDE specifications. Various colors and sheens can be chosen.

Black oxide is a type of conversion coating for ferrous materials, such as steel and stainless steel, which blackens the top layer of the material. It can be used to reduce reflection and glare, as well as provide some additional corrosion resistance without affecting part dimensions.
An electrochemical process that cleans steel parts to reduce corrosion and improve appearance by making the metal brighter. Removes about 0.0001”-0.0025” of the metal and conforms to ASTM B912-02.
Heat treatment of metal parts to provide improved material properties. Includes heat treatment, annealing, and other heat treatments. Specify the treatment required in the 'Notes' section or an attached drawing. Conforms to ASTM B917 (aluminum alloys) or AMS-H-6875 / AMS 2759 (steels).
A colorless coating that improves corrosion resistance for 200 and 300 series and precipitation hardened corrosion-resistant steels by removing free iron from the surface. The coating thickness is negligible at about .0000001”. Conforms to ASTM A967, AMS-QQ-P-35, MIL-STD-171, ASTM A380, or AMS 2700.
Electroless nickel plating provides a uniform nickel coating, which offers protection from corrosion, oxidation, and wear on irregular surfaces. The finished part will appear brighter. Thickness starts at .0001” and conforms to ASTM-B733, TYPE IV, SC1, CLASS 1 (default), or AMS-2404 (formerly AMS-C-26074/MIL-C-26074) if specified. For any other nickel plating options, please select “Other” as the finish option and request a manual quote.
Gold Plating provides good corrosion and tarnish resistance. Gold has low contact resistance, excellent conductivity, and solderability. Cosmetically it makes the part appear like gold. The default application specification is MIL-G-45204 & ASTM B488, CLASS 00, 0, OR 1 (THICKNESS 0.00002" - 0.00005"): Pricing and lead time are based on Type I, II, or III, Grade A, B or C, and Class 00,0 or 1 (thickness of 0.00002" to 0.00005"). Any gold plating thickness over 0.00005" should be selected as "Other" and requires a manual quote.
Electroplating silver provides good corrosion resistance but easily tarnishes. Silver offers high solderability and electrical conductivity. Cosmetically it makes the part appear like silver. The coating thickness is about .00002”-.0003” and conforms to AMS QQ-S-365D.
A metal plating of conductive materials to provide corrosion resistance. Zinc plating is standard among carbon steels and other alloys that can rust. Zinc plating conforms to the ASTM B633-15 service class I (SC1) specification. The typical plating coating thickness is 0.0002.” The finish results in a low silver shine.
This is a batch-based process that tumbles vibrating media to remove sharp edges and burrs on machined parts. Tumbling can remove machine marks on exterior surfaces creating a more uniform appearance. Parts over 8” may require a manual review.
Provides a continuous, protective color finish on parts using evenly applied, heat-cured paint. Thickness is usually .006”-.012” and conforms to ASTM D7803 and various MIL and FDE specifications. Various colors and sheens can be chosen.

Plastic Injection Molding Finishes
Xometry has access to a diverse marketplace of molding suppliers and all standard mold finishing options. Mold finishes can range from glossy to matte to even patterned. Finishes applied to the surface of the mold cavity transfer to the surface of the molded part. For example, a mold surface that is polished to be reflective will make a reflective (or transparent) part. Mold finishes differ from CNC machined or 3D printed parts, where each component is treated individually. Adding a finish or texture can change the tool's price depending on the process required, but it does not alter the price of the individual parts.
Our standard mold finishes include the following:

Standex Engraving Mold-Tech is a standardized mold texturing option typically used for commercial or saleable goods. Mold-Tech is serialized in four series, A through D. Most commonly, the Mold-Tech Series A finishes are used on products as it has a range of fine to coarse matte finishes that do not require laser, masked chemical etching, or other engineered texturing processes. Mold-Tech finishes are categorized by their serial number and texture depth. Below you’ll see examples of popular Mold-Tech finishes that we offer.
MT-11010
