Debinding systems manufacturer LÖMI GmbH, based in Grossostheim, Germany, has launched two new solvent debinding units to meet the increasing demand from research institutes, universities and corporate R&D departments for small-sized systems. The EBA-30 and EDA-30 tabletop units are also suitable for prototyping, for part producers to evaluate Powder Injection Moulding, and for low volume production, for example in the luxury goods sector.
The two systems, which are based on well-proven technology, have a batch volume of 16 litres and offer two-in-one functionality by integrating the debinding and drying of parts. This saves time and cost as no additional handling of the brown parts is required between the debinding and drying process steps. The EDA-30 unit adds a third functionality, integrated solvent recovery, with a recovery rate of up to 99%. This ensures a continuous supply of fresh debinding medium. Together with their compact and energy-saving designs, the two new systems are claimed to be both extremely economical and environmentally friendly.
In recent years LÖMI has reported that a number of PIM part producers have switched to solvent debinding. This offers a number of advantages, including a greater freedom of feedstock choice for Metal Injection Moulding and Ceramic Injection Moulding part producers as a wide range of feedstocks can be processed using the solvent debinding process.
Ralf Wegemann, Marketing Director at LÖMI, told PIM International, “This makes it easy for part producers to test new kinds of feedstock, or to add another feedstock producer as a supplier, without having to invest in a new debinding system. In addition, various organic solvents can be employed, such as ethanol, isopropanol and acetone. At the same time, solvent debinding systems offer very compact dimensions and a very long lifetime, as the solvent debinding process causes very little wear and tear.”
The company has been actively involved in the Powder Injection Moulding industry since 2001 and all its debinding systems have been developed in close cooperation with renowned research institutes and universities, feedstock manufacturers and PIM part producers. LÖMI’s portfolio of solvent and water debinding systems ranges from tabletop units to large-scale industrial plants with over 1,000 litres of batch volume.
