EUROGUSS 2015: Industrial gases specialist Messer presents a process that uses nitrogen to deburr zinc die-cast products

In die casting, it is hardly avoidableto prevent the formation of thin burrs at the seams – burrs which must then be removed after the casting process The use of liquid nitrogen and a gentle blasting medium allows this to be done fully automatically and without causing any damage. Deburring zinc, aluminium, titanium and magnesium die castings is thus made easy. This technology can dramatically reduce costs and reject rates – and the industrial gases specialist Messer will be demonstrating how from 12 to 14 January 2016 at EUROGUSS in Hall 6 / 6-241.

"The buyers of die castings, for instance in the car industry, have increasingly demanding requirements with regard to quality and precision," explains Thomas Böckler, Application Specialist at Messer. "On the other hand, the manufacturers themselves have an interest in both high-quality and more efficient processes. For example, in the case of electronic components, which may only cost a few cents, manual deburring is out of the question. Here our process offers the optimal solution. Moreover, the unit costs per kilogramme of die casting are approximately 95 per cent lower compared with explosive deburring."

It is easy to find out whether it is worth investing in a new cryogenic deburring facility. "First of all, we carry out a free deburring test with the customer’s products," explains Thomas Böckler. "They can then gauge whether the result meets their expectations, and we can calculate whether contract deburring or the company’s own facility would offer the optimal solution."

Messer will participate at EUROGUSS from the stand of MEWO GmbH & CO. KG.
