Units for injection molding debinding (MIM/ CIM)
1. Debinding principle
Powder Injection Molding is a process to produce complex components and assemblies; particularly in the range of ceramics- and metal component manufacturing
-Metal Injection Molding (metal powder)
-Ceramics Injection Molding (ceramics powder)
The benefit of this process is in the feasibility to realise an efficient manufacturing method
1. for bigger number of pieces each production lot
2. and/ or components of technologically advanced level
by ideal compliance with preset tolerances.
The Powder Injection Molding process takes place in 4 phases:
1) Material preparation
In the first instance ceramics or metal powder is being homogenised with organic binder so that the powder particles are sheathed with the binder. The produced compound is chaaracterised as "Feedstock".
2) Molding
In this phase the feedstock is injected in liquid temperated steel tool forms. After solidification the so-called green part ist removed from the tool form.
3) Debinding
In the following debinding phase the binders, which were feeded in phase 1, are removed from the green parts by special solvents and their extraction. After this process the components are called brown parts.
4) Sintering
Finally the porous brown parts are compressed by the thermal process: firing respectively sintering. That way the components get their definite form and material property.
