Featherweights with
strong capacities

Aluminum is the ideal solution for situations requiring strength, good mechanical and chemical properties, enormous conductivity, high corrosion protection and weight savings. The most modern process technology is present in the new production hall, covering 2,000 square meters, and equipped with the latest in aluminum die-casting machines and smelting furnaces. The casting processes in the machines – under automatic, real-time control – are continuously logged. Extensive process monitoring by way of trend data and trend charts guarantees the greatest flexibility in the process. User-specified casting curves allow for even the most demanding applications – especially thin-walled, die-cast parts with high and dynamic fill pressures, for example.

Aluminum die casting for exceptional parts

Kalmbach has the most innovative die-casting technology on hand, in the form of 10 CNC-controlled, liquid-charged, cold-chamber, die-casting units with from 2,500 kN to 8,800 kN of clamping power. Automated with robots and trimming technology, die-cast aluminum parts can be produced in weights of from 10 g to 9,500 g. The central shaft-type smelting furnace and the integrated combination of the temperature-maintenance and metering furnace guarantee constant temperature for the aluminum alloys used here: 226D, 230D, 231D and 239D. Impellers are used to achieve the highest degree of purity in the aluminum melt. The materials being used are monitored and quality is documented by regular spectral analysis. Shot-by-shot regulation makes for highly demanding shapes in small and medium production runs.
