Our Metal Bending Process at LTC Proto
At LTC Proto, metal bending is a precise process where we use CNC press brakes and other advanced bending equipment to form metal sheets into specific angles and shapes.
Our process begins with detailed CAD file analysis, followed by the selection of the right tooling and bending technique, such as V-bending, U-bending, or air bending. By applying controlled force, we achieve clean, accurate bends without compromising the material’s strength.
With our skilled technicians and strict quality control, LTC Proto ensures every bend meets exact specifications, whether for prototypes or large production runs.

Available Finishes
After fabrication, we offer a range of finishing services to enhance the appearance, durability, and functionality of your parts.
| Name | Color | Application/Materials | Description |
|---|---|---|---|
| As Machined | N/A | All Metals | A raw, unpolished finish that retains the natural appearance of the metal. |
| Powder Coating | Custom Colors | Stainless Steel, Aluminum, Brass | Durable, protective finish applied in a powder form and then cured. |
| Bead Blast | Matte or Satin Gray | Aluminum, Stainless Steel, Copper, Titanium, etc. | The part surface has a smooth, matte finish. |
| Anodize (Type II Or Type III) | Custom Colors | Aluminum, Titanium | Type II anodizing provides a corrosion-resistant finish with various color options (clear, black, red, gold) for aluminum, while Type III adds a thicker, wear-resistant layer for enhanced durability. |
| Brushed Finish | Customizable | Stainless Steel, Aluminum, Brass, Copper | A textured, matte finish created by brushing the material surface with abrasives, offering a sleek, modern look while maintaining a high resistance to wear and corrosion. |
| Passivation | N/A | Stainless Steel, Steel, Aluminum | A chemical treatment process that enhances the corrosion resistance of metals by removing free iron from the surface and creating a protective oxide layer, improving durability and longevity. |
| Electroplating | Varies (e.g., Silver, Gold, Chrome, Nickel) | Stainless Steel, Brass, Copper, Aluminum | A process where a metal coating is applied to a surface using electrical current, providing a durable, corrosion-resistant finish with enhanced appearance and performance. |
