Toilet Fill Valve / Float Arm
A plastic toilet fill valve was designed with a brass rivet to function as a link pin/axle upon which the float arm would rotate. The brass rivet was expensive and added a secondary operation which decreased manufacturing efficiency. As riveting relies upon impact to form the head it also introduced the potential for variation in ‘fit’ as well as scrap due to impact/over-compression. An alternate solution was required that would reduce piece price, increase efficiency, and eliminate potential quality issues associated with riveting.
