Other machinable plastics, most of which are highly dissimilar to aluminum, include PC, ABS+PC, PP, PS, PMMA (Acrylic), PAGF30, PCGF30, DHPE, HDPE, and PPS.

The mold is prepared according to the desired shape of the final product. The mold should be clean and free from any debris or contaminants.

One stumbling block is price. As a high-performance polymer, PEEK is one of the more expensive machinable thermoplastics, making it suitable only for machining projects where ubiquitous materials like aluminum are unusable.

Like POM, PTFE (Teflon) is a highly machinable thermoplastic which is an excellent electrical insulator. Unlike POM, however, PTFE is also resistant to high temperatures (up to 260°C), making it a viable aluminum alternative for high-temperature applications.

For CNC machining projects, aluminum is one of the most popular material choices due to its desirable physical properties. It is strong, which makes it ideal for mechanical parts, and its oxidized outer layer is resistant to corrosion from the elements. These benefits have made aluminum parts common across all industries, though they are particularly favored in the automotive, aerospace, healthcare and consumer electronics spheres.

The finished product may require additional finishing processes, such as trimming, sanding, or painting, to achieve the desired appearance and dimensions. Overall, the production of CRP is a complex process that requires careful selection of materials and precise manufacturing techniques to ensure the final product meets the desired specifications.

One of the main reasons why engineers choose aluminum for their machined parts is because, quite simply, the material is easy to machine. While this would appear to be more of a benefit for the machinist manufacturing the part, it also has significant benefits for the business ordering the part, as well as the end-user that will eventually use it.

If aluminum remains the preferred material choice for a project, there are ways to combine CNC machining with other manufacturing processes in order to create more complex, higher-performing aluminum parts. Doing so can maximize the functionality of aluminum while reaping the benefits of multiple production processes.

Die casting is a manufacturing process in which molten metal is forced into a mold cavity with high pressure. It is generally used when making parts in larger quantities since the required tool steel dies are expensive to make.

Although not the most common machining material, the lightweight metal magnesium offers many of the benefits of common aluminum alloys. In fact, magnesium is one of the most machinable metals out there, making the machining process fast and efficient.

The process also produces unique advantages: it can be used to create more intricate parts than would be possible with die casting, and parts emerge with no parting lines.

Definition: Carbon fiber reinforced plastic (CFRP) is a composite material made of carbon fibers and a polymer matrix. The carbon fibers are embedded in a resin matrix, typically epoxy, which provides the structure and binds the fibers together.

Carbon fiber reinforcedpolymer material properties

Vacuum bagging is commonly used in industries such as aerospace, automotive, and marine to create lightweight and strong parts such as wings, fuselages, and boat hulls.

CNC machining projects need not be limited to metals. In fact, several engineering thermoplastics can match or exceed some of the benefits of aluminum, depending on the application.

Also, its high chemical resistance makes PTFE (Teflon) a popular machining material for parts that will be used in the food industry.

Here are some potential machining alternatives to aluminum, with an emphasis on their differences and similarities to the popular silver-gray metal.

Investment casting is a metal casting process that uses wax patterns to create metal parts. Like other casting processes, it produces parts with an excellent surface finish and high dimensional accuracy.

In addition to being an all-in-one manufacturing process, CNC machining can be used to refine or modify parts made using other machinery. Extrusion, casting and forging processes can each be complemented with the machining process to make better aluminum components.

Machined aluminum parts are especially popular in the consumer electronics industry, not just for strength and weight demands, but because of important aesthetic considerations. As well as being receptive to paints and tints, aluminum can be treated with anodization, a surface finishing procedure that thickens the protective and oxidized outer layer of the part.

The forged pieces of aluminum can be post-machined with a CNC machining center. This can be beneficial compared to machining alone since forged parts are generally stronger than fully cast or fully machined equivalents. However, post-machining allows for the creation of more complex geometries without wholly compromising the integrity of the part.

Carbon fiber reinforced plastic (CFRP) is a lightweight and high-strength composite material that has gained popularity in various industries. The unique characteristics of CFRP have led to its use in a variety of applications, from aerospace and automotive to sports and recreational equipment. In this article, we will delve into the world of carbon fiber-reinforced plastic, exploring what it is and the common applications of CFRP.

Machining titanium is a suitable alternative to aluminum when lightweight is a primary concern and, importantly, when the manufacturing budget has some flexibility.

The weight of filament-wound CFRP components may be reduced by up to 20% while maintaining mechanical qualities that are on par with those of other CFRP parts produced from woven textiles. The process is characterized by high accuracy and traceability. An affordable and effective unit cost is easily within reach, even with small series.

Vacuum bagging is a manufacturing process that involves the use of a vacuum to remove air from between layers of materials during the curing process. It is an application of the reinforced plastic manufacturing process that is commonly used to create composite parts with high strength and stiffness.

This article explains some of the key advantages of aluminum CNC machining — reasons why it is one of our most widely requested prototyping and production processes — but also suggests machining alternatives to aluminum.

Aluminum has desirable physical properties that make it ideal for both mechanical and aspect parts. Two of the most important are the metal’s high strength and its lightweight, both of which make the material favorable for critical parts such as those required in the aerospace and automotive industries. Aircraft fittings and automotive shafts are two examples of parts that can be successfully machined with aluminum.

Businesses may seek alternatives to aluminum for CNC machining for any number of reasons. After all, the metal has a few weaknesses: its oxide coating can damage tooling, and it is generally more expensive than alternatives like steel, partly due to the high energy costs of aluminum production.

One potential downside for machine shops? Magnesium chips are extremely flammable and are aggravated further by water, which means machinists must take caution while clearing debris.

The anodization process, which generally takes place after machining is completed, involves passing an electric current through the part in an electrolytic acid bath and results in a piece of aluminum that is more resistant to physical impact and corrosion.

ABS is commonly used as an injection molding material and, as of recent years, a 3D printing filament. But while ABS has very little in common with aluminum, it remains a versatile and lightweight material for CNC machining, offering above-average impact strength.

3D printing is a process of creating three-dimensional objects by layering materials on top of each other.  Carbon fiber-reinforced polymers (CFRPs) can be used in 3D printing to improve the strength and stiffness of the printed parts.

The carbon fiber is cut to the desired length and orientation. The fibers are then coated with a sizing agent to improve adhesion to the polymer matrix.

Aluminum also offers specific advantages that simplify and improve the process of CNC machining. Unlike many other metals with similar material properties, aluminum offers excellent machinability: many of its grades can be effectively penetrated by cutting tools, chipping easily while being relatively easy to shape. Because of this, aluminum can be machined more than three times faster than iron or steel.

Combining aluminum extrusion and CNC machining is a great way to produce resilient parts with complex cross-sections and irregular geometries.

POM is an electrical insulator, making it suitable for parts like electronic enclosures. It is also suitable for mechanical parts. However, given its radically different insulating behavior compared to aluminum, it should only be used as a like-for-like replacement in situations where thermal and electrical conductivity is of negligible importance.

Though PEEK is harder to machine than the previous two thermoplastics, its high strength and thermal stability (resistant to temperatures up to 260°C) make it a genuine like-for-like alternative to aluminum. PEEK’s popularity for machining parts like valves, bearings, pumps, and nozzles testifies to its metal-like abilities.

However, different grades of aluminum serve different purposes. Because of their favorable strength-to-weight ratio, general-use grades like 6061 can be used for a wide variety of parts, while notably high-strength grades like 7075 may be preferred in aerospace and marine applications.

Along with steel, magnesium, and zinc, aluminum is one of the more popular metals for pressure die casting, and die-cast aluminum parts generally have an excellent surface finish and dimensional consistency.

The choice between glass fiber and carbon fiber reinforced plastic depends on the specific requirements of the application. Glass fiber may be a more cost-effective and environmentally friendly option for applications that do not require high strength and stiffness, while carbon fiber may be more suitable for high-performance applications where weight reduction and high strength are critical, even though it is more expensive and harder to manufacture.

A metal with a golden appearance, brass is a highly machinable metal available at a slightly higher price point than aluminum. It is commonly seen on parts such as valves and nozzles, as well as structural components, while its high machinability makes it suitable for high-volume orders.

CNC machined aluminum parts can be useful for electrical components due to their electrical conductivity. Though not as conductive as copper, pure aluminum has an electrical conductivity of about 37.7 million siemens per meter at room temperature. Alloys may have lower conductivities, but aluminum materials are significantly more conductive than, for example, stainless steel.

Another benefit of aluminum is its high recyclability, which makes it preferable for businesses seeking to minimize their environmental impact or for those who simply want to reduce material wastage and recoup some of their expenditure. Recyclable materials are particularly important in CNC machining, where there is a relatively large amount of waste material in the form of chips from the cutting tool.

Since aluminum is often favored for its excellent machinability, one viable plastic alternative is POM (Delrin), which is, like aluminum, highly suited to the machining process. POM has a low melting point but impressively high strength for a plastic.

Titanium may be used as a like-for-like replacement for aluminum since its primary advantage is an exceptional strength-to-weight ratio — also one of the main benefits of aluminum. Titanium has a similar weight to aluminum but is almost twice as strong. Like aluminum, it is also highly resistant to corrosion.

Carbon fiber reinforcedPolymer cost

Aluminum alloys are a common material used for investment casting, and the cast aluminum parts can be post-machined for refinement.

The carbon fibers are arranged in the mold according to the desired orientation and thickness. The fibers are then impregnated with the polymer matrix using a vacuum or pressure process.

Different aluminum grades differ greatly in their resistance to corrosion — the degree to which they can withstand oxidization and chemical damage. Fortunately, some of the most popular grades for CNC machining are the most resistant. 6061, for example, offers excellent corrosion resistance, as do other alloys on the lower end of the strength spectrum. (Strong aluminum alloys may be less resistant to corrosion due to the presence of alloyed copper.)

However, there are also some limitations to CFRP. For example, it is relatively expensive compared to traditional materials, which can limit its use in some applications. Additionally, CFRP can be brittle and prone to damage from impact or puncture, leading to material failure if not detected and repaired in a timely manner. Finally, CFRP can be difficult to repair or modify once it has been formed, posing a threat of more challenging maintenance than with traditional materials.

EuroPlas is the world’s largest masterbatch manufacturer, specializing in the production of engineering plastic compounds. EuroPlas plastic engineering compound is the optimal solution with flexibility, high quality, and all functions in just one material.

Aluminum 6061, for example, is suited to hot forging with a closed die — a process commonly used to produce automotive and industrial components.

Unless, of course, the part is modified after extrusion. Because aluminum extrusion tends to involve malleable, ductile and machinable aluminum grades like 6061 & 6063, the extruded parts can then be post-machined — cut in various ways using a CNC machining center.

Molding is a manufacturing process that involves shaping the material into a specific form using a mold or die. In carbon fiber-reinforced plastic molding, reinforcing fibers, such as carbon fibers or fiberglass, are combined with a polymer resin to create a composite material. This composite material is then shaped into a specific form using a mold, which can be made of metal, plastic, or other materials.

Our experience with CNC machining and fine detailing means we can produce a wide range of aluminum machined parts, from small and simple to large and complex.

These advantages are reflected in the higher price point of titanium. Though the material is an excellent choice for parts like aircraft components and medical devices, its cost can be prohibitive.

Steels and stainless steels are widely used materials in CNC machining. Because of their high strength, steels tend to be favored for high-stress applications and those that require strong welds. Steels are resistant to very high temperatures, and stainless steels can be heat treated to enhance their corrosion resistance.

Extrusion is the process of forcing molten material through an aperture in in a die, producing an elongated component with a continuous profile. While aluminum extrusion is an effective way of producing functional components with quality surface finishes and complex cross-sections, it is limited in scope, since those cross-sections must be consistent across the part.

Gravity dies casting can be used instead of pressure die casting if reducing cost is more important than ensuring high precision or creating thin walls.

Many machinable aluminum alloys are also suited to the age-old process of forging, which involves shaping metal through compressive force. (This often involves hitting the metal with a hammer.)

The first step in producing CRP is to select the appropriate carbon fibers and polymer matrix. The carbon fibers used should have high tensile strength and modulus, and the polymer matrix should have good adhesion properties.

The most common alternative to carbon fiber is glass fiber.  Look at the table below to get a complete comparison between these two materials.

These advantages can be combined with the advantages of CNC machining. By die casting aluminum components then adding further cuts using a machining center, it is possible to create parts with an exceptional finish and more complex geometries that would be possible using either process on its own.

Reinforced plastic filament winding is commonly used in industries such as aerospace, defense, and energy, where high-performance cylindrical structures are required. For example, filament winding is used to create rocket motor cases, pressure vessels for gas storage, and wind turbine blades.

Filament winding is a manufacturing process that involves winding continuous reinforcing fibers around a mandrel in a specific pattern to create a composite material. In reinforced plastic filament winding, the process can be automated, which allows for high precision and consistency in the final product. The resulting structure is then cured to bond the reinforcing fibers and the resin together, and the mandrel is removed to reveal the final part.

However, while machining steels are engineered for improved machinability, aluminum remains the more machinable of the two materials. Steels are also heavier and have a higher hardness than aluminum, which may or may not be desirable depending on the application.

Importantly, anodizing makes it easier to add color to a machined aluminum part, since the anodized outer layer is highly porous. Dyes can find their way through the porous sections of the outer layer and are less likely to chip or flake since they are embedded within the tough exterior of the metal part.

The mold is then placed in an oven or autoclave to cure the polymer matrix. This process typically involves heating the mold to a specific temperature and pressure for a specific amount of time.

Copper shares several material properties with aluminum. However, the superior electrical conductivity of copper can make it preferable for various electrical applications. While pure copper is difficult to machine, many copper alloys offer similar machinability to popular aluminum grades.

However, one of the main challenges of using reinforced plastics in 3D printing is ensuring that the reinforcing materials are distributed evenly throughout the printed part. To overcome this challenge, manufacturers often use pre-made composite filaments or add reinforcing materials to the printing material during the printing process. The use of computer-aided design (CAD) software can also help to ensure that the printed parts meet the desired specifications.

Because aluminum chips easily, and because it is easy to shape, it can be cut quickly and accurately with CNC machine tools. This has some important consequences: firstly, the short timeframe of the machining job makes the process cheaper (because less labor is required from the machinist and less operating time is required from the machine itself); secondly, good machinability means less deformation of the part as the cutting tool goes through the workpiece. This can allow the machine to meet tighter tolerances (as low as ±0.025 mm) and leads to higher accuracy and repeatability.
