We will be exhibiting at MD&M West 2024 to be held at the Anaheim Convention Center, Anaheim, California, USA from February 6 to 8, 2024.
Come visit us at Booth 432 in Hall E to ask us your medical device development or manufacturing questions. We look forward to working with you on bringing metal components for your medical devices from concept to creation.
If you would like to request an appointment with our attendees, please submit a request at info@micro-mim-europe.com.
Conclusion
Cracking, slumping or blistering is commonly observed due to the binder swelling and/or residual stress difference between the surface and interior. It is possible to avoid these problems by selecting appropriate organic solvents and temperature control.
The catalytic deboning uses sublimation of binder, thus it is possible to decompose the binder in relatively short processing time with minimizing the deformation. However, with a strong acidic atmosphere, theapplicable metal material option is limited.
In the sintering process, the necking, which is bridging the metal powders by thermal diffusion, starts at the sintering temperature. Once the necking starts, the shrinking is observed and increases the density, thus before starting the necking reaction, all the organic components should be decomposed and gas between the powders should be removed. In the sintering process, the unwanted chemical reaction, such as oxidation or carbonization, leads to mechanical property loss, therefore a precise atmosphere control with low heating rate at the beginning of the process is required. Also, when it reaches the sintering temperature, some add it vegetal can be evaporated.
