METHOD OF FORMING A COMPONENT FROM A GREEN PART

摘要

A method of forming a component (28) from a part (28') in the green state, includes selecting at least one first portion (44) of the part (28') to undergo a different local volume reduction from at least one second portion (46) to obtain the component. The green part (28') is provided with the first portion(s) (44) having a first solid loading and the second portion(s) (46) having a second solid loading different from the first solid loading, then debound and sintered to obtain the component (28). The different first and second solid loadings produce the different local volume reduction in the first portion(s) (44). The first portion(s) (44) can be selected by determining a resulting final shape obtained from debinding and sintering a green part (28') having a uniform first volumetric proportion of binder, and selecting the first portion(s) (44) requiring a different local deformation than that producing the resulting final shape to obtain a desired final shape.
