Horizon’s Aluminum Extrusion Services
At Horizon, we go beyond standard extrusion. With trusted partners, we provide small-batch aluminum and plastic extrusion services, perfectly suited for prototyping and low-volume production.
Our partners operate 30+ extrusion presses of varying tonnage, all ISO 9001:2015 certified, capable of producing complex aluminum profiles with precision.
Unlike most suppliers that only offer extrusion, Horizon takes it further:
We are equipped with a wide range of high-precision CNC machines for secondary machining, delivering a true one-stop solution—from extrusion to finished product. This means faster development, smoother production, and peace of mind for our customers.
Aluminum Extrusion
Aluminum extrusion is a process that shapes aluminum into specific profiles. The aluminum is heated and forced through a die, producing continuous profiles with uniform cross-sections. It can create a wide variety of complex shapes, with lengths cut to specification, and is easily adaptable for secondary processing such as cutting, drilling, or CNC machining. Commonly used alloys include 6061 and 6063.
Plastic Extrusion
Thermoplastics come in many varieties, with common examples including polystyrene, nylon, polypropylene, and polyethylene. By heating and melting the material, then extruding it through molds, products with various cross-sectional shapes can be produced.

Materials for Custom Aluminum Extrusion
Our standard alloy range offers a variety of strengths, corrosion resistance, and machinability, making it widely used in the construction, automotive, and electronics industries. Below are the materials we commonly use.
High-strength aluminum alloys offer excellent corrosion resistance and good machinability, making them ideal for structural components, mechanical parts, and automotive applications that demand high strength. They are also easy to weld and fasten, facilitating subsequent processing and assembly.
AL6063 exhibits excellent heat dissipation, moderate strength, and good corrosion resistance, with outstanding anodizing performance. It is widely used in LED heat sinks, electronic device enclosures, air conditioner condenser fins, and architectural profiles such as doors and windows.
Finishing Options for Aluminum Extrusions
The aluminum extrusion process is widely used for the mass production of non-aesthetic components, where surface treatment requirements may not be high. However, custom aluminum extrusions can also be used to manufacture high-value products, which can significantly enhance both appearance and functionality through surface treatments such as anodizing, laser engraving, and painting.
Surface treatment processes suitable for aluminum extrusions include:
Anodizing
An oxide layer is formed on the aluminum surface through an electrochemical process, enhancing corrosion and wear resistance, while allowing coloring to improve aesthetic appeal.
It is suitable for components requiring high corrosion resistance and decorative applications, such as electronic enclosures and architectural profiles.
Sandblasting
High-speed sandblasting is used to clean and roughen the surface, producing a uniform matte finish. It is suitable for decorative components and enhances coating adhesion, often used in combination with anodizing.
Powder Coating
Powder coating involves spraying powdered paint onto the aluminum surface and then baking it to form a durable, corrosion-resistant, colored protective layer. It is suitable for outdoor structures, architectural profiles, and appliance enclosures.
Painting
Liquid painting involves applying a coat of liquid paint, allowing for a variety of colors and gloss finishes. It is suitable for aluminum components that require high aesthetic appeal or specific brand colors.
Brushing
Brushing or matting uses mechanical methods to create fine linear textures or a matte finish on the surface, enhancing tactile and visual appeal. It is suitable for decorative components, such as furniture and electronic device panels.
Laser Engraving
Laser engraving or etching uses a laser to inscribe text, patterns, or logos on the surface with high precision and permanent results. It is used for brand logos, decorative designs, or functional markings.
Quality Assurance
Driven by excellence, we embed quality into every detail—from advanced tools to rigorous standards. We ensure consistent, outstanding quality.
