Mathematical model for condensed-solvent debinding process of PIM
Journal of Materials Processing Technology, 2003Abstract Based on Fick’s diffusion law, mathematical model for specimens with simple shapes such as slab, sphere and cylinder are developed for condensed-solvent debinding process of powder injection molding. A graphical method is introduced to forecast the debinding process using the established model while complicated calculation could be avoided ...

Abstract Mn-Zn ferrite components were successfully produced using Powder Injection Molding (PIM) from a binder system (11.5 wt%) made of paraffin wax (PW), linear low density polyethylene (LLDPE) and stearic acid. Solvent debinding kinetics of the molded parts depended on n-hexane temperature, on immersion duration and on part’s geometry. The volume

Master debinding curves for solvent extraction of binders in powder injection molding
Powder Technology, 2012Abstract This study successfully extends the master sintering curve concept to model removal of polymeric binders in powder injection molded bodies. In this demonstration the focus is solvent debinding. Master debinding curves (MDC) were used to estimate the activation energy for debinding.

Solvent debinding mechanism for alumina injection molded compacts with water-soluble binders
Ceramics International, 2003The solvent debinding process has been widely accepted in the ceramic injection molding (CIM) industry process due to its short debinding cycle. However, the organic solvents most adopted in solvent debinding now are flammable, carcinogenic and not environmentally acceptable.

Solvent debinding kinetics of alumina green bodies by powder injection molding
Ceramics International, 1995Solvent debinding of alumina green bodies shaped by powder injection molding is investigated. Debinding is carried out in normal hexane (n-C6), normal heptane (n-C7) and normal octane (n-C8), at 50, 60 and 80 °C. Wax is the major constituent being leached. A shrinking core is observed at the early stage of 50 °C solvent debinding. Debinding kinetics is

A model for PEG removal from alumina injection moulded parts by solvent debinding
Journal of Materials Processing Technology, 2007Abstract The solvent debinding of a water-soluble binder in ceramic injection moulding (CIM) was investigated. The removal of polyethylene glycol (PEG) from alumina injection moulded parts was carried out at room temperature in water. Discs of different thicknesses were submitted to the water bath in order to obtain curves of time against remaining ...

The use of co-solvents in supercritical debinding of ceramics
Journal of the European Ceramic Society, 2002Abstract Extraction of organic binders (paraffin waxes) from injected green ceramic parts, by using supercritical fluids, has proven to be very efficient (short time of extraction, no defects in the green part). The extraction is more rapid when the binder is in the liquid state due to capillary migration but the capillary pressure could damage the ...
