Finishing Options for Aluminum Bends

Milled: Choose this finish option for fastest delivery. Parts will leave visible tooling marks and may have sharp edges and burrs that can be removed upon customer request.

Anodizing: Hardcoat and Color (Black Hardcoat, Black, Blue, Gold, Grey Hardcoat, Green, Natural Hardcoat, Natural, Orange, Red)

Powder coating: This process applies powder coating to the part, which is then baked in a high temperature oven. The result is a hard outer layer that resists wear and corrosion, and is more durable than standard painting methods. Available in a variety of different colors to create the desired look.

Roller coating: Roller coating uses a rotating roller as the carrier of the coating. The coating forms a wet film of a certain thickness on the surface of the rotating roller, and then contacts the object to be coated with the help of the rotating roller during the rotation process to coat the surface of the object to be coated. . Roller coating is suitable for flat coating, widely used for coating metal plate, plywood, cloth and paper, especially for metal coil coating.

Polishing/electropolishing: It is the modification of the surface of the workpiece with polishing tools and abrasive particles or other polishing media to make the surface bright and smooth.

Heat treatment

• Tempered
• Annealing

Custom made

Other processes and surface treatments are available upon customer request.

Bending equipment

CNC bending machine: vibration eliminates internal stress, high mechanical strength, torsion axis synchronization, high precision.
