Kansas Plastics Co. was having problems with a part, so it called Kice Industries Inc. But this was no typical project — the issue was edible doggie bones.
Kansas Plastics, a custom molder in Wellington, Kan., molds the wheat-based bones as a side product. The material is essentially pelletized flour, run on an injection molding machine. The pellets have properties similar to plastic pellets.
But fines were causing the bones to crumble.
Kice determined that fines could be cleaned from the pellets using one of its 6DT4 Multi-Aspirators, modified to mount directly to the throat of the injection press. The Multi-Aspirator uses the principle of terminal velocity to vacuum fines up and away from the pellets, so cleaned pellets then drop right through. The fines are conveyed to a Kice Cyclone Collector, then into a hopper for disposal.
The dog bone system required one modification, however. Because the blow of material was continuous, sometimes causing it to fill completely, Kice designed a small hopper to sit between the aspirator and the injection press. When a level sensor in the hopper showed it was full, the flow slowed to allow proper cleaning.
Now Rover is happy. But it didn't stop with dog bones. Kansas Plastics decided to move the Kice system to one of its other molding machines, making a drain pan that also had problems with fines. The pans are made of glass-filled polyester that has some regrind. The Kice equipment worked.
Kice Industries is based in Wichita, Kan.
