For the shrinkage and deformation of product parts during injection molding and sintering

Release time:2021-04-14 16:41:18

 

In view of the shrinkage and deformation of product parts during the injection molding and sintering process, the following problems need to be solved:
1. Directly observe the overall size change law of the product parts during the sintering process and the local bending deformation law of the parts affected by gravity;
 
2. The non-contact measurement method is adopted to avoid the influence of the loading force of the contact measurement ejector pin on the debinding and sintering deformation;
3. The large-area measurement method is used to directly test the deformation of the formed part to avoid the lack of representativeness of the sample preparation;
 
4. Realize the simultaneous measurement of the two-dimensional deformation of the formed part or sample, and have the function of simultaneously measuring multi-point position changes;
5. Observe the changing law of component size under different heating systems (such as different heating and cooling speeds and different constant temperatures);
 
6. Observe the influence of different atmospheres (vacuum, argon, nitrogen, hydrogen, etc.) and different pressure conditions on the dimensional changes of parts, as well as the influence of switching atmosphere conditions and constant pressure in different temperature intervals on the dimensional changes of parts;
7. At the same time, it has a high-precision high-temperature thermal expansion coefficient test function.
