Analysis of Shrinkage and Deformation of Product Components during MIM Metal Injection Molding and Sintering Process

We need to address the following issues regarding the shrinkage deformation of product components during the sintering process of metal injection molding:

Firstly, directly observe the overall dimensional changes of product components during the sintering process and the local bending deformation of components affected by gravity;

Secondly, use non-contact measurement methods to avoid the impact of contact measurement on the loading force of the top rod on the adhesive discharge and sintering deformation;

The third method is to use a large area measurement method to directly test the deformation of the formed part to avoid insufficient representativeness of the sample preparation;

Fourthly, achieve simultaneous measurement of two-dimensional deformation of metal injection molded parts or specimens, and have the function of simultaneous measurement of multi-point position changes;

Fifthly, observe the changes in component size under different heating systems (such as different heating rates and constant temperatures);

Sixth: Observe the effects of different atmospheres (vacuum, argon, nitrogen, hydrogen, etc.) and pressure conditions on the variation of component size, as well as the effects of switching atmosphere conditions and constant pressure in different temperature ranges on the variation of component size;Simultaneously equipped with high-precision high-temperature thermal expansion coefficient testing function.
