Surface Finishes at Tonza's system
High-quality surface finishing enhances both the aesthetics and functionality of your parts, regardless of the manufacturing process.
Surface Finishes
We provide expert finishing for metals, composites, and plastics, helping bring your prototype or product vision to life.
| Name | Description | Materials | Color | Texture | Pic |
|---|---|---|---|---|---|
As Machined | As Machined means the part is left in the exact condition it comes out of the machining process (CNC milling, turning, drilling, etc.), without any additional surface treatment or polishing. | Metals, Plastics, Other Machinable Materials | N/A | As machined |
|
Brushing | Brushing is a surface treatment technique that enhances aesthetics by creating decorative lines on a workpiece through grinding, resulting in a visually appealing finish. | Aluminum, Brass, Stainless Steel, Steel, ABS,etc | N/A | Satin |
|
Sand Blast | Sandblasting uses high-speed sand flow to clean and texture a product's surface, achieving the desired level of cleanliness and roughness. | All Metal Materials, Plastic | N/A | Matte |
|
Tumbling | Tumbling smooths surfaces, deburrs edges, and enhances uniformity using a rotating drum with abrasive media. | All Materials | N/A | Smooth, Matte |
|
Polishing | Polishing uses abrasives or buffing wheels to smooth surfaces, remove imperfections, and create a shiny, reflective finish. | All Materials | N/A | Smooth |
|
Anodizing | Anodizing enhances aluminum by adding a protective layer, improving corrosion resistance, wear resistance, hardness, and appearance. | Aluminum, Titanium | Clear, Yellow, Green, Blue, Black, etc | Smooth, matte finish. |
|
Painting | Secure the product on a rotating bracket and apply paint evenly. This enhances texture but may be prone to scratches. | All Materials | Clear, Yellow, Green, Blue, Black, Multiple | Gloss, semi-gloss, flat, metallic, textured |
|
Black Oxide | Black oxide forms a protective film on steel and stainless steel, enhancing corrosion resistance, appearance, and reducing light reflection. | Steel, Stainless Steel | Black | Smooth, matte |
|
Electroplating | Electroplating enhances function, appearance, and corrosion resistance, widely used in industries like automotive for chrome-plated steel parts. | Aluminum, Steel, Stainless Steel | Gold, Silver, Nickel, Copper, Brass, Zinc, Chrome | Smooth, glossy finish |
|
Powder Coating | Powder coating electrostatically applies dry powder to metal, then cures it with heat or UV light for a durable, attractive finish. | Aluminum, Stainless Steel, Steel,etc | Custom | Gloss, matte or semi-gloss |
|
Alodine | Alodine finish is a conversion coating for aluminum, creating a protective film that prevents corrosion and acts as a primer for painting. | Aluminum, Stainess Steel | Clear, Gold | As machined |
|
Passivation | Passivation enhances stainless steel's corrosion resistance by immersing it in an acid solution to remove contaminants and form a protective oxide layer. | Stainess Steel | N/A | Matte |
|
Electroless Plating | Electroless plating deposits metal onto a substrate through a catalytic reaction with a metal ion solution, creating a uniform, adherent coating without an external electrical current. | Metal, Plastic | Gold, Silver, Nickel, Copper, Brass, Zinc, Chrome | Smooth, glossy finish |
