There are many benefits of impact extrusion. Whether combined, forward or backward extrusion, there is a high level of dimensional accuracy and the possibility to achieve a close approximation to the final shape. Offering 100 percent tightness, impact aluminum extrusion allows a high degree of transformation in a single production step, high operating speeds at low unit costs and numerous shaping and design possibilities. In addition, impact extrusion provides compact structure, a smooth surface, no soldered or welded seams and excellent stability.

Aluminium extruded holder is available to suit 5mm 8mm & 10mm brush strip. It is available in 45 degrees, 90 degrees, and 180degrees to suit the brush strips application. Other types of holder are available on request. Bespoke products are also availablefor high end finishes and requirements. Call us to discuss your needs. Our professional & expert staff will always be able to help wherever possible.

Molybdenum-hafnium carbide (MHC) is highly temperature-resistant, has a high level of thermal conductivity, a low coefficient of thermal expansion and a high recrystallization temperature. MHC retains its shape even when used at temperatures of up to 1 550 °C. At temperatures up to 800 °C, MHC is suitable for use in die inserts. At higher temperatures, the producer recommends using MHC for full dies. The benefits to you for a long service life: — Optimum nondeformability and dimensional stability — Low tendency to crack in the case of edged profiles — High thermal stability — High thermal conductivity — Low thermal expansion — Good hot ductility — Very high recrystallization temperature Plansee supplies MHC components in disc form with or without drilled start hole.

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.
