Planetary Mixers

overview a planetary mixer operates by combining planetary rotation with centrifugal force the mixing container spins on its axis while orbiting around a central point, ensuring effective blending and dispersion of materials different planetary mixers are required for different container sizes some important points to consider when using planetary mixers fastest non mmd process times simple process high price point sealed mixing container mixing capacity up to 2000 g kakuhunter sk 300sii the table below compares the two models of planetary mixer that have been validated by carbon mixer max capacity hands on time machine time total process time equipment cost kakuhunter sk 300sii 300 g 3 minutes 6 minutes 9 minutes $$$ kakuhunter sk 1100t 2000 g 5 minutes 7 minutes 12 minutes $$$$ equipment & accessories planetary mixer this mixer generates strong centrifugal force during operation because of this, a counterbalance must be placed opposite the resin container smaller models can have an adjustable weight built into the mixer larger models may require the addition of a second container filled with water or an equivalent amount of resin model max capacity tips price kakuhunter sk 300sii 300 ml $$$ kakuhunter sk 1100t 1100 ml x2 = 2200 ml can mix two 1100 ml containers at once $$$$ best practice dictates using 50% of the total capacity for mixing (for example, 150 ml of a 300 ml cup) this ensures good mixing action see the kakuhunter processing capacity handout below for information kakuhunter technical documents general processing capacity of kakuhunter mixers kakuhunter sk 300sii (300 ml capacity) read first quick start user manual kakuhunter sk 1100t (2200 ml capacity) user manual mixing cups planetary mixing containers or cups typically feature a container with a seal and screw lid to keep resin contained during the high speed rotation of the mixer various sizes and adapters are available for planetary mixers operation consult the product manual for specific instructions about operation load the mixer push the inner seal into the top of the cup screw the lid over the seal and cup insert the cup into the mixer make sure it is aligned with the tab ensure cup is aligned with tabs set the counterweight follow the instructions for your particular mixer model sk 300sii weigh the total mass of the cup and resin set the counterweight dial to equal the mass of the cup and resin set the counterweight dial sk 1100t in another mixing cup, add water with the same mass as the resin in the resin cup push the inner seal into the cup and screw the lid on place the water cup in the position across from the resin cup alternately, if you’d like to mix more resin, fill the second mixing cup with the same mass (+/ 100 g) as the first close the lid and place across from the first resin cup add secondary cup equal mass to first cup choose the mixing program follow the instructions for your particular mixer model sk 300sii mix for 4 min, 2000 rpm degas for 30 seconds at 2200 rpm sk 1100t preset program 1 remove cups from mixer when mixing is complete, remove the container(s) from the mixer unscrew the lid, remove the seal and dispense resin into the printer cassette begin printing promptly in order to maximize pot life workflow videos kakuhunter sk 300sii video text place inner seal in container and secure lid align tab in mixer with slot on container turn dial to set counterweight using gross weight scale at left kakuhunter sk 1100t video text place inner seal in container and secure lid align tab in mixer with slot on container place 2nd mixing container with an equivalent mass of water or resin in the opposite position
