When a new mold is needed, our engineering team will first communicate with you about possible suggestions for optimizing project costs.
Can I get a sample?
Yes, we are happy to provide you with samples so that you can check our production quality. The price of samples is free in most cases. Submit the form to contact our sales staff for detailed information.
How long does it take to get the sample?
If the sample is in stock, we can express it to you directly.
For customized heat sinks, extrusion production takes a little time, usually 20-30 days to complete.
If you open a new mold, how will you deal with the mold?
We will produce and preserve your molds according to your requirements, and provide mold maintenance and repair services for your subsequent use.
Packaging
Packaging can be customized according to your needs. Options include using protective film or paper to separate and protect the surface, or foam film for additional surface protection. Products can be palletized or packed into cartons, and the quantity per pallet or carton can be specified by the customer.
The standard packaging involves bundling several pieces together with plastic wrap and then securing them onto pallets. Any packaging requirements beyond the standard will be accommodated, and the associated costs will be clearly provided to the customer.
Delivery Time
Mold production typically takes 7 days. After the sample is confirmed, producing a full container load of 26 tons generally requires 14 days for extrusion alone. If surface treatment is required, an additional 3 days will be needed. For machining, extra time will be required depending on the complexity and volume of the machining work. The exact additional time for machining will be determined based on the specific processing requirements.

What is Aluminum Extrusion?
Aluminum extrusion is the process of shaping aluminum material by forcing it to flow through a shaped opening in a die. When extruded in this way, the aluminum material comes out of the die as an elongated piece with a continuous cross-sectional profile, and this profile can be highly complex and detailed.
For non-specialists, an easy explanation of extrusion is to think about how pasta shapes or Play-Doh are made. In both cases, dough is fed into a chamber, pressure is applied by turning a crank or handle, and strands of the stuff are squeezed out of a small hole. Changing the attachment for this hole affects the cross-section of the strands, giving you the choice between e.g. tagliatelle, penne, or something else.
Of course, aluminum billets aren’t quite as malleable as pasta dough, so the aluminum extrusion process requires a lot of force — typically via huge amounts of hydraulic pressure — and, in some cases, the application of heat.
How the Extrusion Works
The aluminum extrusion process can be carried out in one of two ways: hot extrusion or cold extrusion. There are reasons to use both methods. Hot extrusion allows for greater volumes of aluminum to be fed into the die, quickly and at lower pressure, while cold extrusion can produce mechanically superior parts with a good surface finish and resistance to oxidization.
To extrude aluminum via the hot extrusion process, aluminum billets must first be cut to an appropriate size. They are then heated in an oven to a temperature between 300 °C and 600 °C, making the metal supple but not liquid.
When the cut aluminum billets are heated, a ram powered by hydraulic pressure forces them into the die, which may have a standard aperture (i.e. a round or square hole) or a custom-made profile. A huge amount of pressure — around 10,000,000 pounds — is required to force the heated aluminum through the die.
The extrusions are then cooled on a cooling table, before being cut into lengths according to the customer’s demands. Heat treatment can also be applied to harden the aluminum.
Aluminum Extrusion Manufacturing Process Flow
The aluminum extrusion process starts with preheating aluminum billets to make the metal malleable. Once the desired temperature is reached, the billet is pushed through a precision-engineered die using a hydraulic press. As the aluminum exits the die, it takes on the shape of the die opening, forming a continuous profile.
After extrusion, the profile is cooled using air or water quenching systems, then mechanically stretched to eliminate internal stresses. The profiles are cut to the required lengths and may undergo further heat treatment (like aging) to achieve specific mechanical properties. Each stage of the process is carefully controlled to ensure dimensional accuracy, surface quality, and structural integrity in the final product.
Common Extrusion Applications
Extruded aluminum is used in countless industries due to its versatility and strength-to-weight ratio. It plays a vital role in architecture, transportation, electronics, solar energy, and industrial automation.
For example, T-slot profiles are widely used in modular framing systems, while heat sinks are essential in LED lighting and electronic cooling. Its adaptability makes aluminum extrusion indispensable in modern engineering.

Common Aluminum Alloys Used in Extrusion
Different aluminum alloys offer unique combinations of strength, corrosion resistance, and machinability. The most commonly used alloys in extrusion include 6061, 6063, and 6082, each suited for different applications.
6063 is ideal for architectural and decorative profiles due to its superior surface finish. 6061 offers greater strength, making it suitable for structural uses. 6082 provides excellent mechanical properties and weldability for heavy-duty applications.
Extrusion Shapes & Profile Types
Aluminum extrusion allows the creation of a wide range of shapes, from solid bars and tubes to intricate custom profiles. These include T-slots, heat sinks, channels, angles, and hollow sections.
Whether standardized or customized, profile design is crucial in optimizing material usage, reducing weight, and improving assembly efficiency. Custom dies allow tailored geometries for unique mechanical or functional requirements.
Finishing Options for Aluminum Extrusions
Surface finishing enhances both the appearance and durability of extruded aluminum. Common finishes include anodizing, powder coating, polishing, sandblasting, and more.
These treatments not only improve corrosion resistance and color uniformity but also provide decorative appeal. The right finish can meet functional needs while aligning with your product’s design and branding goals.
Deep Processing & Customization
In addition to extrusion, many components require deep processing such as CNC machining, drilling, cutting, welding, and assembly. These value-added services streamline production and reduce lead time.
Our in-house capabilities enable complete customization according to your drawings and technical requirements. This integrated approach supports precision manufacturing, higher efficiency, and simplified supply chains.
Why Choose Aluminum Extrusion?
Aluminum extrusion offers numerous advantages: it enables complex shapes, reduces weight, and lowers manufacturing costs compared to other methods. It also supports sustainability due to aluminum’s recyclability.
With efficient tooling, high dimensional accuracy, and scalable production, extrusion is ideal for both prototyping and large-volume manufacturing. It balances design freedom with functional performance.
