The EBO debinding furnace is specially engineered to handle the stringent requirements that come with catalytic debinding.
The EBO is an ideal solution for binder removal from mouldings made from BASF Catamold® Feedstock. These mouldings are commonly known as green parts. The debinding furnace reaches a maximum temperature of 150°C and is available in two sizes: 120 litres (rectangular usable space 400 mm x 400 mm x 700 mm) and 250 litre (rectangular usable space 500 mm x 500 mm x 1000 mm).
Metal injection moulding (MIM) and Ceramic injection moulding (CIM) is an expanding modern manufacturing technology. MIM and CIM manufacturing processes comprises of 4 steps: compounding raw material into feedstock, moulding feedstock to the desired shape creating a green part, debinding and sintering. Debinding is the most demanding operation in this process. The debinding of Catamold® feedstock is performed catalytically with nitric acid. This process demands precise control of both the temperature profile and gas pressures.
With the EBO debinding furnace the operator may choose between a fixed debinding time and a fully automatic self-detecting debinding. The automatic adjustment is able to detect the end of the debinding process and terminates the cycle. CIM applications are limited to a sample wall thickness of approximately 4 – 5 mm. The furnace is fitted with safety interlocks to guarantee operational safety. Operation and visualisation of the process appears by means of a touchpanel.
