Extrusion Machining - Learn About Extrusion Machining Centers
Extrusion machining is MODIG’s expertise. We have developed and produced extrusion machining centers for more than 30 years and done over 30,000 time-studies and surveys. The MODIG extrusion machining solutions, an awarded design, became the first choice of top-performing machine shops. We know the requirements placed on extrusion machines today and what is needed to achieve a higher productivity. On this page, you can take part in our knowledge about extrusion machining. You get a background in extrusion as a manufacturing method and how a machine works while presenting our unique machine solutions for extrusion parts.

What is an extrusion machining center?
To understand what an extrusion machining center is, you need to overview the extrusion process itself briefly.
The extrusion process
Extrusion is a metal-forming manufacturing method used to create objects with specific cross-sectional profiles. The material will be pressed through a pre-shaped die. The process is a bit like squeezing toothpaste out of a tube. Imagine the toothpaste as a heated, cylindrical aluminum bar called an ingot. The toothpaste tube is the tool itself. The hot material is pressed through a tool/matrix that shapes the profile. When the profile leaves the tool, air or water cools it down. Then the shapes are stretched while they are still ’soft.’ This way, stresses are released in the aluminum, and the profiles finally get the correct dimensions. The profiles are cut and get their final strength through hot or cold aging. The next step is finishing or surface treatment to enhance appearance and corrosion properties. After the surface treatment, you can use an extrusion machining center to process the profile further and produce parts according to your specific requirements.
Extrusion machining center
An extrusion machining center is a machine used to precisely cut and shape the extrusion to a finished part. To achieve the desired shape with pockets, holes, and other features the extrusion machining center utilizes various techniques such as sawing, deburring, drilling, turning, milling, and tapping. Its responsibility is to ensure the extrusion is cut and shaped perfectly. In MODIG’s machine portfolio, you will find several machining centers for extrusion machining. Our machines are known for their speed and reliability in this type of machining. MODIG’s machines can significantly reduce production time and minimize waste during processing, making them a top choice on the market. Contact us to learn more about the MODIG solutions!
MODIG is at the forefront when it comes to manufacturing machining centers for aluminum extrusions. All the extrusion machines we offer make a big difference in product quality as they simultaneously help to minimize production costs and ensure that the customer achieves the desired productivity. We will now focus on how our extrusion machines complete parts in one setup.
Extrusion machining in one setup
MODIG’s extrusion machines are perfect for producing components. For example, the automotive and aerospace industries have. The MODIG solution is available with two or three rotary tables and one or two spindles to process straight bars and profiles of aluminum and composite material. The raw material is continuously loaded onto the machine from the left and automatically pulled into position for machining. No pre-cutting is required before the raw material is pushed through the pre-designed jaws and processed in the machine. Details are machined in a single process without the operator needing to reset and realign the machine when milling at different rates. Rather than cutting the raw material into specific lengths, MODIG’s extrusion machines handle extrusions in full size, resulting in a reduced setup time, no work holding, and a significant reduction in cycle time.
Extrusion machining is used today in many industries because it is both surprisingly cost-effective and time-efficient for the right parts. The automotive industry has been using extrusion solutions for many years. In particular, the manufacturers of Electric Vehicles require this type of machine to manufacture parts and components, such as battery trays, battery enclosures, and much more. The aerospace industry has also benefited from the advantages of extrusion. Aluminum Extrusion has also become increasingly common in construction due to its high strength-to-weight ratio and cost advantages. In addition to commercial applications, the Extrusion Machining industry has discovered several other industries that make extensive use of the extrusion process.
MODIG has been at the forefront of extrusion machining centers featuring rotary tables for over thirty years. We have gained valuable insights into the extrusion machining process through constant improvement and customer feedback. Our HHV2, HHV3, and HHV DUO aluminum extrusion machining centers can handle any extrusion shape in a single setup without any workholding required. We have compiled a collection of our extrusion machining videos to assist you in comprehending the HHV process. So, sit back and enjoy a fantastic movie session.
