The Question
A manufacturer asked ZERO to help clean and etch the external surfaces of carbon steel tubes to enhance the bond strength of heavy chrome plating. The customer wanted a Ra
range of 100 to 200 microns, to ensure maximum adhesion of the plating. After plating, the tubes are installed in the hot dog cookers found in ballparks and convenience
stores worldwide.
The three sizes of tube are the same ID and OD, but range in length from 14 to 32 inches. Each tube has a gear welded to one end that mates to the drive motor.
The customer's existing process - manual blasting - produced an acceptable surface for plating, but took several minutes per part and put the employees at risk of repetitive
motion injury. The customer needed to get at least 100 parts per hour to justify the switch to automated blasting.
