Newest garbage disposals feature super-quiet, ultra-powerful motors.
Units are made from combination of carbon steel and stainless steel.
All parts are made in Racine, Wisconsin, plant, which manufactures more than 6 million garbage disposals annually.
Each rotor is shrink-fitted onto the drive shaft for efficient transfer of power.
Dampening devices and thick foam insulation are employed to cut vibration and reduce noise levels by 60 percent over other disposals.
Motor fits into an insulated housing, which helps muffle grinding noise.
Latest disposals are equipped with newly designed shredder plates and shredder rings that produce super-fine grindings, which greatly reduce plumbing clogs.
Random disposals are regularly taken off the assembly line and tested; each unit must successfully grind up a variety of fruit and vegetable scraps, 35 pounds of frozen beef bones and six pounds of wooden blocks.
