Binder<br />
Production Equipment<br />
• safe and enviromentally friendly system<br />
• simple machine construction<br />
• easy binder removal in water<br />
• waste water may discharged into sewer<br />
Process and Product Characteristics<br />
> easy handling of process<br />
Water bath<br />
> short cycle times<br />
> cost efficient even at room temperature<br />
> high strength of brown part
In order to ensure sufficient inter-particle porosity, the water-soluble content of the binder<br />
makes up approx. 55-60 % by volume of total binder system.<br />

polyMIM ® concept of water debinding<br />
polyMIM ® kinetics of debinding process<br />
polyMIM ® line layout/examples
The components are placed on sinter trays or perforated metal plates during the injection<br />
moulding process.<br />

BILD
The stack of trays is pushed into the debinding unit and the door is locked.<br />
polyMIM ® CONCEPT OF WATER DEBINDING<br />
- Batch debinding -<br />
Loading
The closed processing chamber is flooded and depending on the type of alloy a corrosion<br />
inhibitor is added.<br />
polyMIM ® CONCEPT OF WATER DEBINDING<br />
- Batch debinding -<br />
Inhibitor<br />
Flooding
The temperated water is circulated until the programmed debinding period has expired.<br />
polyMIM ® CONCEPT OF WATER DEBINDING<br />
- Batch debinding -<br />
Binder removal<br />
at 40-60°C<br />
Inhibitor<br />
Circulating water
The binder removal takes place starting from the surface to the moulding center thus<br />
preventing warpage or deformation.<br />
polyMIM ® CONCEPT OF WATER DEBINDING<br />
H 2O<br />
Binder<br />
Water bath
Water debinding creates the intra-particle porosity necessary for thermal debinding.<br />
polyMIM ® CONCEPT OF WATER DEBINDING<br />
Backbone binder<br />
Pores<br />
Water bath
After the debinding time has expired the water is discharged and discarded, the process<br />
water does not have to be purified.<br />
polyMIM ® CONCEPT OF WATER DEBINDING<br />
- Batch debinding -<br />
Sewer
After binder removal the components are air- or vacuum-dried to constant weight.<br />
polyMIM ® CONCEPT OF WATER DEBINDING<br />
- Batch debinding -<br />

Bending strength in MPa<br />
The brown part strength is just 40% below green part strength and thus offers a<br />
favourable residual strength.<br />

polyMIM ® Water treatment<br />
It is recommended to use demineralized water for the<br />
debinding process.<br />
Demineralized water is obtained<br />
by using demineralization<br />
cartridges which desalinate the<br />
water.<br />
The threshold of 20 µS/cm should<br />
not be exceeded.
