Enjoy the last autumn walks through an alley, surrounded by colorful leaves – Compamed is just around the corner!
In exactly one month, on November 17, 2025, we from Micro MIM USA and Taisei Kogyo Thailand will be in Düsseldorf at Booth: 8AP10 Location Hall 08A. Can’t wait to welcome you!
Our hot moulding stories are ready to heat up your winter – come by, chat with us, and see what we have in store.
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.
