Our Precision CNC Machining Services

When customers customize prototypes, some parts are suitable for the extrusion process, and we are often asked if we can provide small batch extrusion molding services. Because of this, we started looking for extrusion suppliers to meet these needs. Unfortunately, the search results are frustrating. Large extrusion companies have no interest in small batch production, while small extrusion companies cannot meet our quality requirements. This presents challenges, but we see it as a business opportunity: if we have a hard time finding the right companies for these projects, we know that overseas customers will have a hard time finding them.
With the recommendation over time, we have successfully established relationships with a small number of medium-sized extrusion partners who can meet our quality requirements and lead time requirements. We are now able to extract plastic and aluminum extrusion services.

Custom Low Volume Extrusion Services

Plastic Extrusion

Plastic materials include polystyrene, nylon, polypropylene, and polythene. These are thermoplastics: they are heated and then pressured in a mold which can form them into different shapes and sections.

Aluminum Extrusion

Aluminum extrusion is defined as the process of shaping aluminum material by forcing it to flow through a shaped opening in a die. Aluminum material emerges as an elongated piece with the same profile. Alloys we commonly work with include: 6061, 6063.

Our Advantages of Precision Machining

If you are looking for extrusion profile cutting of a certain length and your order volume is large, then you should definitely work directly with an extrusion company. There are many extrusion companies that handle high-volume production. Still, these companies are reluctant to handle low-volume aluminum and plastic extrusion projects unless you’re one of their VIP clients. Therefore, it is difficult to obtain prototype aluminum profiles and prototype plastic profiles. We have a reliable partner for short-term custom aluminum profiles and short-term plastic extrusion services. They take good care of our project in terms of quality and delivery time. We also perform routine quality control of your project before shipment.

Compared with traditional extrusion companies, we have a large amount of CNC machines, so we can do precision post-machining in house.


We offer custom plastic & aluminum extrusion profiles, and we can combine extrusion with other manufacturing methods such as CNC milling, turning, and bending to make the final parts.

Low Volume

Most extrusion companies set a very high MOQ. We don’t, so we’re the best choice for small batches. One-time prototype extrusion or several hundred units? Never mind.

Fast delivery

If you don’t want to wait 30+ days to get your extrusion mold and profiles manufactured, come to us! We can finish everything in half the industry-standard time or even less.

Custom Aluminum Extrusion Profiles

Standard aluminum extrusion profiles (like extruded aluminum channel or extruded aluminum bar) are typically mass manufactured by extrusion specialists; if you need large quantities of standard extruded aluminum profiles, you are better off using the services of one of these companies.
  However, for custom aluminum extrusion profiles with a nonstandard aluminum extruded shape, we may be a better option. That’s because we accept low-volume extrusion orders — for prototyping and small batch production — allowing you to experiment with custom profiles.
   In addition to creating custom aluminum extrusion profiles using custom dies, we can combine extrusion with other manufacturing processes (like CNC machining) to produce custom final parts. This can allow us to make parts faster and more affordably, especially if the majority of the part has a consistent cross-section.

Applications of Aluminum Extrusion

Aluminum extrusions are used in heavy industry, aerospace, the food industry, and elsewhere. Common aluminum extrusions include extruded aluminum heatsinks and profiles for tracks, frames, and rails. Industrial: Extruded aluminum can be used to make industrial equipment like workbenches and carts, as well as extruded aluminum frames / extruded aluminum framing. Standard framing systems include extruded aluminum T-slot structural framing (80/20 extruded aluminum framing). Construction: Architecture and construction provide several uses for aluminum extrusion such as extruded aluminum rails, balustrades, and ladders. Electrical: Aluminum is electrically conductive and is therefore useful in its extruded form for lighting components such as LED aluminum extrusions, solar panel support structures, and more. Transport: Extruded aluminum is good for fabricating items like automotive, horse, and boat trailers.

Finishing Options for Aluminum Extrusions

Aluminum extrusion is used to mass produce lots of non-cosmetic parts like tubing and frames, where finishing may not be especially important. However, custom aluminum extrusion is also used to produce high-value products which may benefits from the addition of color, text, logos, and other finishing procedures.

Suitable surface finishing procedures for aluminum extrusion include:

Basic mechanical finishing:
Treatments like buffing, bead blasting, and grinding can be carried out to adjust the surface quality of aluminum extrusions, sometimes in preparation for other surface finishes.
Anodization: Aluminum extrusions can be anodized to give them a scratch-resistant and oxidization-resistant coating with an excellent cosmetic appearance.
Painting: Whether the part needs a matte, gloss, or textured finish, painting is an effective way to alter the color and surface appearance of an aluminum extrusion.
Powder coating: Powder coating is a suitable alternative to anodizing, giving excellent chemical resistance and consistency of tone.
Silk-screen printing: One of the simplest ways to add text and logos to aluminum extrusions, silk-screen printing is cheaper than machine-based finishing procedures.
Laser engraving: Laser engraving can be used to add detail, including text, to an extrusion, and it will not rub off over time. It is therefore useful for essential features like part serial numbers.

Standard Aluminum Extrusion Profiles

Custom aluminum extrusion profiles can be cut to any 2D cross-sectional shape. However, there are several standard aluminum extrusion profiles suitable for many projects, including extruded aluminum bar and extruded aluminum channel of various forms.

Standard profiles include:
Circular bar | Square bar | Circular tube | Square tube | L-shape | U-shape | T-shape | C-shape | J-shape | F-shape
Profiles also come in standard sizes and series. These include:

2020 aluminum extrusion (20 mm x 20 mm)
80/20 aluminum extrusion (T-slot aluminum extrusion)
2040 aluminum extrusion (20 mm x 40 mm)
3030 aluminum extrusion (30 mm x 30 mm)

Aluminum & Plastic Extrusion FAQ

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.

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.

We specialize in low-volume manufacturing. If you require a small to medium-size order, other companies may not accommodate your needs.
Our most commonly used alloys are 6061 and 6063, which contain high levels of magnesium and silicone. Both are highly corrosion resistant. You may specify a different aluminum alloy, and we will review the feasibility when providing you with a quotation.
We have a selection of trusted extrusion partners who fulfill our orders, but 3ERP will do post-machining and check the parts before shipment.

Aluminum is the most abundant metallic element in the earth’s crust. The metals industry smelts more than 40 million tons per year, and manufacturers use them for a variety of applications.

Like most metals, aluminum is found as an ore in rocks throughout the earth’s crust. Mining companies extract almost all of their aluminum metal from bauxite, which typically contains 30 to 60 percent alumina (or alumina). The rest is a mixture of silica, various iron oxides and titanium dioxide.

Two-step process to convert alumina to aluminum:

1. Extraction of alumina from bauxite

Almost all of the world’s alumina supply is produced using the Bayer process. Austrian chemist Carl Josef Bayer developed this technique in the late 19th century.

It involves crushing bauxite into a fine powder, mixing it with water and heating the mixture with caustic soda. Caustic soda dissolves the alumina and passes it through the filter.

Producers add aluminum hydroxide crystals to an alumina solution, which is then heated and dried to produce alumina.

2. Smelting alumina to produce aluminum metal

To smelt aluminum, refineries dissolve alumina in a fluorinated bath and use an electric current to break it down into metallic aluminum and oxygen through a process called electrolysis. They then collect the aluminum and take it to a furnace, where they combine it with the recycled aluminum material and heat it until it is melted.

It is then poured into a mold or mechanically extruded in various forms. The most common are plates, billets, bars, tubes, plates, bars and wires. They are then cut into different shapes and sizes and shipped to another company or manufacturer who will process them into countless products.
