MIFA ALUMINIUM B.V. - Rely on the power of precision

Mifa has an extensive range of modern CNC-controlled machinery. Nevertheless, we prefer to use machining work as little as possible. Thanks to the combination of precision extrusion, CNC machining, and surface treatment, we can shorten the total production time for machining and improve the quality of the product. We write the software ourselves and make our own moulds for the CNC machining. Every profile is different and often demands a specific processing method, particularly if it is a visible surface. To this end, we use CAD/CAM programmes such as Solid Works, Solid Edge, and Unigraphics. We also develop the clamping tool ourselves too. The right clamping method is crucial in order to achieve the desired result. The best clamping method is dependent on factors including the dimensions and thickness of the profile and the processes to be implemented.

EN-755-9 and EN-12020-2 are the accepted norms for the extrusion of aluminium profiles. They allow deviations of 0.15 mm or more. Mifa ignores these norms and applies precision extrusion of 0.02 mm. We’re unique in the world! And it gives countless possibilities. Bulk production. Standardised work. Inaccurate. These are words that you’ll hear often if you ask engineers for the features of extrusion. But there is another option. Mifa’s delivery starts from 10 kg, and we offer custom-built products and precision, also for straightness, torsion, concentricity, parallelism, surface roughness and tting. Add to this the outstanding features of aluminium – post-processing is often not needed – and it becomes clear that precision extrusion would be useful for many applications. Even as a replacement of other techniques and materials.

Anodizing, galvanizing, passivation, painting: Mifa offers customers all possible surface treatments. A good surface treatment can protect against corrosion, reduces wear or friction, can be electrically insulating or conductive, and in many cases makes the product visually more attractive. Mifa sees surface treatment as the nishing touch that not only increases durability but also adds extra functionality to the aluminium product. The main surface treatments for aluminium that Mifa offers can be roughly divided into three categories: - Conversion layers: aluminium passivation, anodizing, and plasma electrolytic oxidation - Galvanic coatings: chemical nickel-plating, silver, gold, tin, hard chromium etc. - Organic coatings, painting, paint primers, adhesive primers CVD (Chemical Vapour Deposition), PVD (Physical Vapour Deposition), and synergistic coatings can also be applied on request.

Proper bending of aluminium and magnesium requires specific knowledge of the material. The phase in the process in which the material is bent is also crucial to the final result, right after pressing or only after hardening, for example. There are many techniques for bending, such as roll forming, press (brake) bending, swivel bending, deep drawing, stretch forming, and 3D bending.
