Benefits of precision extrusion for aluminium profiles

Many engineers are unaware that precision extrusion can offer huge advantages over many alternative techniques such as machining, roll forming, and milling. We're pleased explain how this technique could improve your product or production process and why it will often save you time and money!

Read on and we’ll set out how aluminium precision extrusion can help you optimize your product.

What is precision extrusion?

Put simply: when extruding, the aluminium is heated in a kiln until it is soft enough to be formed. The temperature varies per alloy and is very important for the final result. The hot aluminium is then pressed under great pressure through a mould that determines the final shape of the profile. Once the profile has been extruded, it is cooled, stretched, hardened, and cut to size, after which any necessary finishing can be applied.

Examples include milling, drilling holes and surface treatments. The profile can then be assembled into a finished or semi-finished product.

The animation below shows how the extrusion process works.

Compare extrusion companies

Before delving deeper into the world of precision extrusion, let's start with a short introduction to the various providers.

It’s important to know that not every extruder (extrusion supplier) can or will offer you what you need. Many extrusion companies focus on pressing large quantities of aluminium. Mifa, on the other hand, focuses mainly on high quality, complex aluminium extruded profiles. We don’t make things unnecessarily complex, but a complex profile is often the part in a product that can make a difference. This could be because it has a complex shape, has to be very thin-walled or may have a maximum dimensional tolerance of just ±0.02 mm. This is precisely the level of detail that Mifa excels in.

The range of different alloys also makes Mifa unique! With fourteen alloys, including aluminium and magnesium, we have a wide range to offer. We also extrudemany other aluminium alloys on request. We’ll be pleased to advise you on this.

Advantages of aluminium extruded profiles at Mifa

  • Considerable freedom of form in the design process
  • Cost savings compared to many production techniques
  • Access to our extensive knowledge and experience
  • We manufacture total products by machining, surface treatment and assembly in house
  • Tolerances from ±0.02 mm
  • Wall thicknesses from ±0.25 mm.
  • Profile weight from 0.003 kg/metre tot 10 kg/metre
  • Profile dimensions from Ø 3 mm to Ø 180 mm / 220 x 60 mm

By using high-end precision extrusion, Mifa can produce the most complex designs for aluminium extruded profiles. No matter how complicated your designs may be, an extrusion mould is relatively cheap and easy to make (compared to moulds of other techniques). This makes precision extrusion a cost-effective alternative to machining, for example.


Aluminium extruded profile designs

Our technology gives you a huge amount of freedom of design. The precision offered by Mifa means that designers can truly let themselves go at their drawing tables. The unprecedented options offer a world of freedom. Designers need make no concessions when designing precision extrusion profiles. At the drawing table, they have no need to worry about restrictions or standards. This freedom of form produces excellent end results.

With the extensive experience of Mifa's engineers at Mifa, we’ll be pleased to assist you in your design process. This enables you to get the best out of your products. Our engineers will be pleased to help you. Co-engineering often results in the best products, in which Mifa’s knowledge of aluminium and extrusion enriches your product knowledge.


From extrusion to machining, surface treatment, and assembly

As we have seen, extrusion at Mifa goes much further than simply pressing aluminium. From profile to product, we offer you maximum relief within the supply chain! We assist our customers from co-creation to assembly and logistics.

Masterclass on aluminium production methods

Because designers and engineers are often insufficiently aware of the possibilities offered by precision extrusion, we offer masterclasses so that they can increase their knowledge and understanding of the options. This makes it possible for you to design the best possible precision extrusion aluminum profile. We give a number of 'standard' masterclasses, both at our own premises and at customer locations, but we’re also more than willing to tailor the content of a masterclass to your needs or issues!

Please contact Frank Loobeek or see our page on masterclasses.

The heart of our business: precision extrusion

Mifa has been the benchmark for decades when it comes to precision extrusion. Everything in our company is focused on optimizing the extrusion product and processing it into a top-quality item.

To this end we regularly renew or improve our presses and broaden and improve our range of machinery with everything needed to improve the production process. From a five-axis CNC machine to the fully robotized production of front forks for KTM.

Our technology, knowledge, and experience enable us to produce highly complex aluminium profiles. However, profiles out of other materials like magnesium can be produced with an accuracy of up to ±0.02 mm. We also outperform the standard when it comes to straightness, torsion, concentricity, parallelism, surface roughness, and fit. This often results in no further processing being necessary, saving you costs.

Mifa is expert in precisie extrusie, machining, oppervlaktebehandeling en assemblage.
