Multicore profiles for various applications
At Mifa, we are renowned for our expertise in extruding complex aluminum and magnesium profiles with many small cores, commonly known as multicore profiles. Cores or cavities within profiles can be necessary for functional reasons or for weight-saving purposes. We extrude from a diameter as small as 0.5 millimeters, providing numerous advantages for the customer.
Complex profiles with cores starting from 0.5 mm
The extrusion of small cores requires a high level of precision. Thanks to the years of knowledge and experience of our engineers at Mifa, it is possible to achieve cores, sometimes no larger than 0.5 mm. This is no easy task, as the smaller the holes or cores, the more challenging it becomes.
The accuracy of this process is achieved using a small pin on the die. This pin forms the core of the profile, and the hot, soft aluminum flows along it under high pressure. The thinner the pin, the greater the risk of breakage. The complexity increases even further when small cores are separated by thin walls, such as one millimeter in thickness.
With our expertise in alloys and the extrusion process, we can press such complex multicore profiles from 0.5 mm, over various lengths.
