Custom-made aluminium enclosures
How do you achieve the ultimate aluminium enclosure?
Precision extrusion
With dimensional tolerances starting from ± 0.02 mm, we go beyond the standard for complex aluminium and magnesium extrusion profiles.
Machining
In a modern machine park with over 30 CNC machines, we carry out all machining operations on aluminium and magnesium profiles.
Aluminium enclosures through precision extrusion
What makes Mifa a unique partner is its precision extrusion technology. We specialise in producing complex aluminium and magnesium extrusion profiles with dimensional tolerances starting from ± 0.02 mm—more accurate than the standard extrusion norm according to NEN-12020-2.
This high precision allows for enormous design freedom, enabling us to co-extrude many functions within the profile. Through clever construction and by assembling multiple small profiles with plates in between, we can create enclosures with unlimited dimensions that are modular and versatile.
”An optimal enclosure is created by applying years of know-how and co-engineering. Together with the customer, the needs and requirements become clear, allowing for a tailor-made solution to be found.”

Functionalities for aluminium enclosures
The functionalities listed below can be directly co-extruded into the profile; this saves on additional machining operations and allows the profile to be used immediately.
- Cooling for motor
- Removable cover for maintenance
- Aesthetic appearance
- Integrated screw channels for fastening the lid or cover profile
- Space for electronics
- Easy motor replacement
Cooling fins
When using electronics, heat is often generated. This heat is dissipated by applying additional cooling profiles. By integrating cooling fins directly into the enclosure, these no longer need to be purchased separately.
Example: a circuit board or electric motor produces heat, which must be dissipated to prevent overheating. Cooling fins increase the surface area, allowing heat to be dissipated faster. The larger the surface area, the better the cooling performance.
Mounting provisions
Integrated mounting provisions in aluminum profiles offer solutions for the easy and efficient attachment of components. Common provisions include:
- PCB mounting points: allowing circuit boards to be directly fixed in the profile without extra holders
- Clamp and angle systems: enabling quick assembly without tools; ideal for modular applications
- Roller or sliding guides: ensuring smooth movement inside the enclosure
- Screw channels: for secure fastening of covers or possible accessories without the need for additional drilled holes
How do you achieve the ultimate enclosure?
By means of smart design and co-engineering, you achieve the ultimate enclosure. One of our leading customers in the field of measuring instruments, Helmut Fischer, manufactures instruments with high-quality aluminium enclosures. These profiles are extruded, machined, and anodised at Mifa.
