Custom aluminium extrusion supplier
High-end custom aluminium profiles with a maximum dimensional tolerance of ±0.02 mm.
Freedom of form in the design process
Firstly, our production process offers our customers a lot of design freedom. Designers can ignore almost all restrictions and standards: at Mifa, you can think in terms of possibilities instead of limitations. Here are some examples of extrusion profiles that Mifa can produce.
Great precision and a high level of detail
Secondly, Mifa excels in producing bespoke aluminium profiles with great precision and a high level of detail. Thanks to our state-of-the art machines we are able to produce thin-walled aluminium profiles with the most complex shapes and with a maximum dimensional tolerance of ±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.
Our experts will be happy to advise you based on your needs and requirements.
Prototyping
Furthermore, Mifa develops prototypes starting from just 10 kg. This is ideal for quickly testing design and functionality before series production. Prototyping also reduces costs and development time while enabling optimisation. With all processes under one roof, from extrusion to post-processing, Mifa ensures the following benefits:
- Efficient production;
- High precision;
- Scalability, from small batches to large volumes.
The extrusion process
Mifa’s extrusion process consists of the following steps:
- Extrusion billets are cut to the required size.
- The billets are preheated to approximately 450 °C and placed in the extrusion press.
- The container moves into position to hold the billet securely.
- The ram pushes the billet through the extrusion die, forming the profile.
- The extruded profile is cooled and cut to length on the run-out table.
- The profile is stretched to ensure straightness, after which the stretch ends are removed.
- Finally, the profiles are collected and undergo a final heat treatment.
Economically advantageous
Mifa’s custom-made aluminium profiles are also economical. Our efficient aluminium extrusion process saves money compared to many other production techniques. Moreover, the cost of an extrusion die is relatively low. So our custom aluminium profiles save you time and money.

One stop-shop
Mifa takes full responsibility for the development and production process of the profiles. Our knowledge and experience in precision extrusion, machining, assembly and all other techniques we master, guarantee an optimal product. Mifa is therefore a one-stop-shop for customers. The techniques below are at our disposal:
- Precision extrusion;
- Machining;
- Assembly;
- Aluminium surface treatments;
- Magnesium technology;
- Other techniques: bonding, welding, marking, engraving and laser processing, bending and pre-treatment.
With our extensive knowledge and years of experience, we use the right technology for each product. A technique that is particularly interesting for our customers, is surface treatment.
Aluminium and magnesium alloys
In order to ensure the best possible end result, Mifa offers a variety of aluminium and magnesium alloys. The reason for this, is that each alloy has unique properties that are best suitable for specific applications. These properties include mechanical strength, corrosion resistance, weldability, ductility, formability and heat resistance.
Next to our aerospace alloys, we supply the following alloys as standard:
Magnesium extrusions
Mifa has mastered the production of high-quality magnesium profiles and components, achieving tolerances as tight as 0.02 mm, similar to aluminium. Magnesium offers the same design flexibility as aluminium but with added benefits.
Key Advantages of Magnesium:
- Lightweight: Magnesium is up to 30% lighter than aluminium and 70% lighter than steel. This weight reduction is crucial for products like bicycles, cars, and airplanes, enhancing performance and user experience.
- Cost Efficiency: Lighter components reduce production, handling, and operational costs in industries like automotive, aerospace, and transportation.
- Durability and Corrosion Resistance: Mifa’s advanced coating technology prevents corrosion, ensuring magnesium remains strong and durable. Its high strength-to-weight ratio makes it an attractive alternative to heavier metals.
Sustainability: a top priority
In addition to supplying high-quality extruded aluminium profiles, Mifa attaches great importance to sustainability. For example, we have our own recycling centre where we separate our raw materials.
Mifa received the silver EcoVadis award in May 2025. With EcoVadis, we measure our progress in the areas of sustainability and corporate social responsibility. This recognition puts us in the top 15% of all companies assessed. EcoVadis is the market leader in assessing the sustainability of hundreds of thousands of companies.
Case study: Exceptional precision for global leader Picanol
For over twenty years, Mifa has partnered with Picanol, a global leader in air-jet and rapier weaving machines. For Picanol, Mifa produces aluminium extrusion profiles with exceptional precision. These profiles, used as guide rails in weaving machines, are essential to the reliability and performance of the equipment.
Through precision extrusion, CNC machining, and in-house assembly, Mifa ensures consistent quality and high production volumes.
