Surface Finishing Services for Custom Enclosure

Improve the durability and appearance of your precision sheet metal fabrication with our surface finishing options. If you need something different, just choose “Other” and tell us what you’re looking for.

As Machined  

sheet metal as machined
As machined finish leaves the surface straight from the CNC machine, providing a cost-effective option with tool marks.

Anodizing

shee metal anodized part
Anodizing increases corrosion resistance and wear properties, while allowing for color dyeing, ideal for aluminum parts.

Hard Anodizing

black oxide coating metal
Hard anodizing increases surface hardness and wear resistance, while providing excellent corrosion protection, ideal for aluminum parts.

Alodine

alodine coating aluminum sheet
Alodine coating provides corrosion protection and improves paint adhesion, mainly used on aluminum surfaces.

Sand Blasting

sheet metal sand blasting
Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.

Polishing

metal polishing sheet metal
Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.

Brushed Finish

brushed finish stainless sheet
A brushed finish creates a unidirectional satin texture, reducing the visibility of marks and scratches on the surface.

Electroplating

electroplating sheet metal parts
Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.

Powder Coating

sheet metal powder coating
Powder coating applies a thick, wear-resistant layer with excellent color and texture options, suitable for a variety of surfaces.

Electropolish

electropolishing stainless sheet metal
Electropolish is a chemical process that smooths and brightens surfaces while improving corrosion resistance.

Painting

Tumbling
Painting adds a protective coating and enhances appearance, with a wide range of color options for custom sheet metal parts.
Heat Treatment
Vacuum Heat Treatment
Heat treatment alters the mechanical properties of metal to increase its hardness, strength, or ductility.

FAQs

The best process depends on your design complexity, material, and production volume. CNC machining is ideal for precision prototypes, sheet metal fabrication suits industrial enclosures, and injection molding is best for high-volume plastic enclosure manufacturing.

Cost depends on material selection, enclosure size, structural complexity, surface finish, tolerance requirements, and production volume.

Custom enclosure manufacturing is the process of producing electrical enclosures, industrial enclosures, or electronic housings based on your CAD design using CNC machining, sheet metal fabrication, injection molding, or die casting.

Common materials include aluminum, stainless steel, carbon steel, ABS, polycarbonate, and fiberglass. The choice depends on strength, cost, corrosion resistance, and application requirements.

Metal enclosures (aluminum or steel) offer higher strength, EMI shielding, and durability, while plastic enclosures are lighter, more cost-effective, and suitable for consumer electronics and low-weight applications.

Yes. We provide custom NEMA enclosure manufacturing services, including NEMA 1, NEMA 3R, NEMA 4, and NEMA 6P enclosures for indoor, outdoor, and harsh environment applications.

Lead time depends on complexity and process. CNC prototypes can be produced in days, while mass production varies based on tooling and volume.

Yes. Our engineers provide DFM review, including structural analysis, material selection, tolerance stack-up, sealing design, and cost optimization before production.
