Freeze Granulation of PIM or Extrusion Feedstock Powder injection molding (PIM) and extrusion are powder shaping techniques that typically involve preparation of high viscous feedstock making it difficult to achieve full homogeneity. Especially if the powders are fine (submicron or nano) and/or if it is a composite material. By doing an initial preparation of a low… Continue reading Preparation of PIM or Extrusion Feedstock

Frysgranulering för tillverkning av homogena granuler
PowderPro har i samarbete med Swerea IVF (då Svenska Keraminstitutet) under 1980-talet vidareutvecklat en alternativ granuleringsteknik – frysgranulering (Freeze Granulation) – vilken möjliggör konservering av homogeniteten från suspension till torrt granulat. Genom att spreja en pulversuspension ner i flytande kväve sker en momentan frysning av dropparna (granulerna). I den efterföljande frystorkningen sublimeras isen utan risk för segregeringseffekter som… Continue reading Frysgranulering för tillverkning av homogena granuler
Freeze Granulation produce flowable and crushable (soft) granules
Freeze Granulation produce flowable and crushable (soft) granules suitable for die pressing applications. Spray drying yield flowable, but hard granules which are difficult to cruch during die pressing. Please contact us and we will further discuss the opportunities with Freeze Granulation on your powder system and read more on technology and we propose a Granulation Test… Continue reading Freeze Granulation produce flowable and crushable (soft) granules
Can you make spherical granules?
Yes, with Freeze Granulation it’s possible to make spherical, homogeneous and dust-free granules with optimal flowability which is critical for automatic uniaxial pressing of for ex ceramics and metal powders. You can expect spherical and homogenous granules of powders in terms of distribution of particle size and other possible additives you want to use. The granules with a… Continue reading Can you make spherical granules?
Homogeneity preservation from suspension to dry granule
If you are looking for optimal homogeneity in your granulated material, then you should evaluate our unique granulation technology – Freeze Granulation! Today, Freeze Granulation is the only granulation technology that will preserve the homogeneity from suspension to dry granule, which is crucial for good results in most processes. Spray cooling or rather called spray freezing… Continue reading Homogeneity preservation from suspension to dry granule
Superabrasive Grinding Tools
Superabrasive grinding tools by Freeze Granulation Freeze Granulation is today being used for the production of high quality superabrasive grinding tools, where the superabrasive grains are homogeneously distributed in the grinding tool. This results in a grinding wheel with higher grinding capacity and longer grinding and cutting tool life. Please contact us and we will further discuss… Continue reading Superabrasive Grinding Tools
Carbon nanotubes deagglomeration
Carbon Nanotubes deagglomeration by Freeze Granulation By using Freeze Granulation it is possible to disperse and avoid agglomeration of Carbon nanotubes. Carbon nanotubes can be granulated and dried into a powder and then re-dispersed to nanopowders again avoiding agglomeration (aggregates) of nanoparticles, which is not possible with other granulation methods like spray drying. Freeze granulation gives the possibility to granulate nanoparticles achieving… Continue reading Carbon nanotubes deagglomeration
