As Machined | No additional finishing; machining marks remain visible. | All metals & plastics | Natural material color | Tool marks, matte to semi-gloss | Prototypes, internal parts, functional components |
 |
Fine Machining | Precision cutting to improve surface smoothness and accuracy. | Metals (Al, SS, Steel) | Natural color | Smooth, low roughness | Precision components, sealing surfaces, assemblies |
 |
Anodizing | Electrochemical coating for corrosion resistance and enhanced appearance. | Aluminum only | Black, silver, gold, blue, red, hard anodized colors | Matte or satin; uniform coating | Housings, brackets, electronics, aerospace parts |
 |
Polishing | Mechanical polishing for reflective or smooth finish. | Aluminum, Stainless Steel, Brass, Copper | Natural (metallic) | Glossy, mirror-like | Decorative parts, medical tools, consumer products |
 |
Bead Blasting | Abrasive blasting to create a uniform matte surface. | Aluminum, Stainless Steel | Natural or anodized color | Fine matte, smooth texture | Electronics housings, enclosures, cosmetic parts |
 |
Black Oxide Coating | Chemical conversion coating for mild corrosion resistance and low reflectivity. | Steel, Stainless Steel | Black | Matte black | Tools, mechanical parts, firearm components |
 |
Brushing | Consistent linear texture to enhance appearance. | Aluminum, Stainless Steel, Brass | Natural color | Brushed line pattern | Panels, covers, decorative surfaces |
 |
Powder Coating | Durable, thick coating for corrosion, impact, and chemical resistance. | Metals (Al, Steel, SS) | Wide range of RAL colors | Smooth, textured, matte, gloss | Frames, enclosures, industrial equipment |
 |
Electroplating | Metallic coating for corrosion resistance and conductivity. | Steel, Brass, Copper, Aluminum (pre-treated) | Nickel, chrome, zinc, gold, tin | Smooth, glossy | Connectors, automotive parts, decorative hardware |
 |
Laser Marking | Permanent marking with high precision and contrast. | Metals & some plastics | Dark/engraved effect | Fine, crisp marking | Logos, serial numbers, QR codes |
 |
Silk Screen Printing | Ink-based surface printing for text, icons, or labels. | Plastics, Aluminum, Stainless Steel | Various ink colors | Flat printed surface | Control panels, device housings, branding |
 |
Heat Treatment | Thermal process to improve hardness, strength, and durability. | Alloy steel, tool steel, stainless steel, titanium | Natural (darkened after treatment) | Slightly roughened or oxidized | Gears, shafts, mechanical components |
