Custom CNC Aluminum extrusion service in China
Aluminum extrusion is a fast process where aluminum is forced through a die to manufacture a specified shape. Since aluminum is strong yet lightweight, easily manipulated, and resists corrosion, aluminum extrusions are widely used in many industries, from construction to transportation.
Our company provides a range of aluminum extruding services. Whether it is high-volume production runs or low-volume prototypes, we can process well. So we have become a partner for many businesses. We also offer a range of surface treatment services to make the aluminium extruding parts more perfect.

Aluminum extrusion manufacturing process

Hot aluminum extruding is when the aluminum billet is heated treatment around 700 degrees Fahrenheit and then pushed through an extrusion die. The release agent is also applied to the extrusion ram to prevent the billet and ram from sticking together.The die gives the aluminum its shape, and as the aluminum cools, it hardens in the new form. It can create a wide range of shapes, such as pipes and tubing.
Cold aluminium extruding is when aluminum leaves the mold. It is cooled and cured with water. Once it reaches room temperature, it is cut to the desired length and removed from the production line. It is commonly used in small-volume production.

Aluminum extruded surface finishing
The extruded aluminum process is used in various applications, from window frames to car parts. It must undergo surface finishing to give extruded aluminum a smooth, finished surface. Surface finishing can be done using various methods, including polishing, anodizing, painting, powder coating,silk-screen printing, and laser engraving.
Polishing
Polishing cleans the aluminium extrusion surface to remove any dirt or debris. Then, polish the surface with sandpaper to make it smooth—finally, use the polish to achieve a high-gloss finish effect.
Anodizing
Anodizing is a process of electrolytically oxidizing the aluminum’s surface, giving it a durable and corrosion-resistant finish.
Powder coating
Powder coating is another option for protecting extruded aluminium from corrosion and wear. It involves spraying the aluminum with a dry powder that adheres to the surface and cures into a hard, protective coating.
Painting
Painting can be suitable for extruded aluminum to give it a vibrant color or to provide a layer of protection from the elements. There are a variety of painting methods that can be suitable for aluminum extrusion, including spraying, roller coating, and brushing.
Silk-screen printing
Laser engraving
Laser engraving is a versatile and precise way to manufacture various designs on aluminum surfaces. It can be customized to create unique and one-of-a-kind products.

Aluminum Extrusion FAQs
We’ve learned that there’s a lot of mixed information online about aluminum extrusion. So here are some of the most common questions we answer for our customers. It helps you quickly understand cnc aluminum extrusion.
What is aluminum extrusion?
Aluminium extrusion is a process that the aluminium billet is forced through the stationary die.
It is then cooled and allowed to solidify. This process can create aluminum in a variety of shapes and sizes.
It is often suitable for the construction industry to create aluminum beams, trusses, and column supports.
The process of aluminium extruding is relatively simple and efficient. Therefore, it is a popular choice for businesses and manufacturers.
The advantages of aluminum extrusion
Aluminum extruding offers several advantages over other manufacturing methods, including high accuracy, repeatability, and flexibility.
Aluminium extruding can create various shapes and sizes. So, it is an ideal choice for applications where precise dimensions are critical.
Additionally, aluminum extruding offers superior strength and durability, making it ideal for products that will be subject to heavy use or exposure to the elements.
Finally, aluminium extruding is a relatively inexpensive process. Compared to other aluminum manufacturing methods, extrusion is typically much less expensive.
In conclusion, aluminium extruding is an essential manufacturing process for many industries.
How to cut aluminium extrusions?
If you need to cut aluminum profiles, there are a few different ways you can do it.
One option is to use a hacksaw.
Hacksaws are specifically designed for cutting metal to make quick work of aluminium extrusion.
Be sure to use a blade designed for cutting aluminum, as regular steel blades will quickly dull.
Another option is to use a power saw, such as a jigsaw or circular saw. If you opt for this method, be sure to use a blade that is designed for cutting aluminium.
Again, regular steel blades will quickly dull when used on aluminium.
Finally, you can also use a router cutter. This method is best for making precise cuts, but it does require more time and effort than the other two methods.
Be sure to take safety precautions and wear protective gear, whichever method you choose.
What shape of aluminum profiles can we customize?
Customers can customize aluminum profiles according to their own needs.
Because aluminium materials have good plasticity, we can extrude aluminum into aluminum products of various shapes and sizes according to customers’ requirements.
There are mainly round aluminium profiles, rectangular aluminium profiles, square aluminium profiles, triangle aluminum extrusions, irregular aluminium profiles, special-shaped aluminum profiles, etc.
We can extrude the aluminum material into various shapes. Customers can choose the shape of aluminum profile according to their own needs.
Only by specifying the shape of aluminum profile can we better customize it.
What is T slot aluminum extrusion?
T slot profile is one type of aluminum extrusion profile.
The “T” shaped slots are cut into the aluminum so they can be interlocked with other pieces of aluminum extrusion profile.
It enables the construction of objects without the need for welding or bolting.
T slot profile has a variety of applications. It is commonly used in industrial machinery, framework, and packaging.
Using a t-slot profile includes creating complex shapes, a seamless finish, and increased durability.
The t-slot profile may be the right choice for your project if you need a high-quality, custom aluminum extrusion.
