In the manufacturing sector, particularly in industries such as aerospace, defense, medical, and automotive, the need for precision-engineered components is paramount. Custom aluminum parts have become a cornerstone of modern manufacturing due to their lightweight properties, excellent strength-to-weight ratio, and superior corrosion resistance. However, traditional manufacturing methods like machining from billet, forging, and extrusions often add significant time and cost to the production process. This is where thixomolding aluminum emerges as a game-changer, offering a more efficient and cost-effective solution.

Understanding Custom Aluminum Parts

These custom parts refer to components specifically designed and manufactured to meet the unique requirements of a particular application. Unlike standard parts, which are mass-produced, custom parts are tailored to the exact specifications of the client, ensuring optimal performance and compatibility. The advantages of using custom aluminum parts are numerous, including:


Custom parts are manufactured to precise tolerances, ensuring they fit perfectly and function as intended.


Tailoring parts to specific applications can enhance the overall performance of the end product.

Material Efficiency

Custom parts reduce material wastage, as they are designed to meet the exact needs of the application.

The Challenges of Traditional Manufacturing Methods

Traditional manufacturing methods such as machining from billet, forging, and extrusions have been the go-to processes for creating custom aluminum parts. However, these methods come with inherent challenges:

Machining from Billet


Machining involves removing material from a solid block (billet) to create the desired shape. This subtractive process can be slow and labor-intensive.

Material Waste

Significant material is wasted during the machining process, which can increase costs.

Complex Geometries

Achieving complex shapes and intricate details can be difficult and time-consuming.


High Cost

Forging requires expensive tooling and dies, making it costly, especially for low-volume production.

Limited Design Flexibility

The design flexibility is limited due to the constraints of the forging process.


Additional machining and finishing operations are often required to achieve the final shape and surface finish.


Design Constraints

Extrusions are limited to shapes that can be produced through the extrusion die, which can restrict design possibilities.

Length Limitations

There are limitations on the length of the parts that can be produced, which may not be suitable for all applications.

Additional Machining

Similar to forging, extrusions often require additional machining to achieve the desired final shape.

Enter Thixomolding Aluminum

Thixomolding aluminum is a revolutionary manufacturing process that addresses the limitations of traditional methods. It combines the advantages of injection molding and die casting, offering a unique approach to producing custom aluminum parts.

What is Thixomolding?

Thixomolding is a semi-solid metal processing technique where the material, in this case, aluminum, is heated to a semi-solid state before being injected into a mold. The key feature of thixomolding is that it uses magnesium alloys, which are processed in a similar manner to plastic injection molding. This process is highly suitable for producing complex and high-precision parts.

Advantages of Thixomolding Aluminum

Cost Efficiency

Reduced Material Waste

Thixomolding minimizes material waste compared to traditional subtractive processes.

Lower Tooling Costs

The tooling costs for thixomolding are generally lower than those for forging and extrusion, especially for complex shapes.

High Precision

Complex Geometries

Thixomolding allows for the creation of intricate and complex geometries that would be difficult or impossible to achieve with traditional methods.

Tight Tolerances

The process can achieve very tight tolerances, ensuring high precision and repeatability.

Design Flexibility

Innovative Designs

The process supports innovative and complex designs that can be tailored to specific applications.

Lightweight Components

Thixomolding can produce lightweight components with excellent mechanical properties.

Speed and Efficiency

Shorter Production Times

The thixomolding process is faster than traditional methods, reducing production times and increasing efficiency.

Less Post-Processing

Parts produced through thixomolding often require minimal post-processing, saving time and costs.
