Our aluminum parts processing options include aluminum extrusion, CNC machining, welding, bending, etc. We also provide a variety of surface treatment options such as anodizing, spraying, sandblasting, electroplating, etc.
A custom designed extrusion die is used to shape the aluminum into a continuous cross-sectional profile suitable for both structural and decorative purposes.
Remove material with high-precision computer-controlled cutting tools. Used for tight-tolerance drilling, milling, slotting, and surface detailing.
Join aluminum parts through TIG, MIG, or friction welding to create strong, seamless assemblies for frames, brackets, and enclosures.
Form aluminum profiles into angles or curved shapes without cutting, using roll bending, rotary draw, or stretch bending techniques.
Create holes, slots, or notches in aluminum profiles using mechanical or hydraulic presses for efficient, repeatable processing.
Use focused laser beams to mark text, logos, or serial numbers onto aluminum surfaces with clean, permanent results.
Electrochemically convert the aluminum surface into a corrosion-resistant, decorative, and dye-absorbent oxide layer.
Electrochemically convert the aluminum surface into a corrosion-resistant, decorative, and dye-absorbent oxide layer.
Apply a dry, electrostatically charged powder finish to aluminum parts, cured by heat to form a durable, uniform coating.
Blast aluminum surfaces with abrasive media to create a matte or textured finish, often used before anodizing or coating.
Deposit an even, protective coating onto aluminum using an electric field in a liquid bath—often combined with anodizing for durability and gloss.
The quality of window aluminum profiles is determined not only by material selection and extrusion precision but also critically by surface treatment. We provide comprehensive surface finishing solutions including anodizing, electrophoresis, powder coating, PVDF fluorocarbon coating, and wood grain finishes.
Anodizing creates a protective oxide layer on the aluminum surface, which enhances its corrosion resistance and surface hardness. This finish is suitable for environments where the partition systems will be exposed to moisture or harsh conditions, providing longevity and maintaining a consistent appearance.
The charged aluminum profiles are immersed in a coating solution in an electrolytic tank. Through electrophoresis, the coating evenly adheres to the aluminum surface. Electrophoretic coating provides good weather resistance, color stability, and a smooth and uniform coating.
Corrosion resistance of composite film: ≥9.5 level
Paint film cohesive: Zero lever
Paint film hardness: ≥3H
Surface: Matte; flat; high brightness
Color: Silver white; bronze; champagne
Features: Corrosion resistant; durable; smooth and shining
Powder coating involves applying a dry powder that is then heat-cured to form a smooth, durable surface. This finish provides excellent resistance to chipping, scratching, and fading, making it an ideal choice for both interior and exterior partition systems that will endure wear over time.
PVDF coating, a type of spray coating, utilizes a PVDF resin-based paint that provides exceptional resistance to weathering, UV radiation, and chemicals, making it suitable for demanding outdoor applications.
Coat thickness:30-65um
Coat shock resistance: No cracking or fall off after shock test
Coat cohesion: Zero lever
Glossiness: 60°
Features: With metallic luster, bright color, high weather resistance
This process involves transferring wood grain patterns or textures onto the aluminum profiles using a transfer method. It gives the aluminum profiles the appearance of wood while retaining the advantages of aluminum, such as weather resistance and corrosion resistance.
Surface texture: Wooden; marble
features: Wood-like visual experience
