All that is now set to change.<\/p>\n

Open-pore foam structures<\/h3>\n

Since last October Hollomet has been using a new plant technology that slashes costs, and this will increase interest in metal foams, which have hitherto been cost-intensive.<\/p>\n

The principle of making foams from metals was discovered some 30 years ago. Their great advantage: they offer an excellent relationship between rigidity and mass. Depending on the type and the structure, metal foams consist to 80 to 90 percent of air. In addition to high stiffness they also demonstrate good damping qualities and have sound and heat absorbing properties.<\/p>\n

In the last decades metal foam structures were employed primarily in vehicle construction for truck superstructures, convertibles or tram cars thanks to the fact that they delivered the right combination of low weight and high stiffness. Moreover, their excellent absorbent properties made them suitable for crash protection.<\/p>\n

Alongside their striking aesthetic qualities (especially in combination with light), metal foam structures also offer air-cleaning and noise-absorbing properties. While previously aluminum (e.\u2009g., Alulight) was largely used to manufacture foam structures, today foam structures can be produced using almost any metal.<\/p>\n

A distinction is made between closed and open-pore foam structures. While closed-pore foams (e.\u2009g., aluminum foams by Gleich, zinc compression foams by Zincopor) are made using propellants, open-pore structures are often achieved by casting (M-Pore) or sintering (Hollomet).<\/p>\n

In the sinter technology process chain, a plastic foam is first coated with a powder metal binder suspension and then the foam is debonded at 300\u00b0 C, and finally the metal is sintered. Depending on the density, what remains is a porous metal foam structure \u2013 with much finer structures than could be achieved using casting.<\/p>\n

Moreover, the geometry of the plastic foams can be selected before the sintering process and the foam structures can be made from various metals (e.\u2009g., iron, stainless steels, silver or gold).<\/p>\n
