Brush Collector Ring Spring


We were contacted by a current customer in the irrigation pivot industry. They were experiencing a great deal of product failure and warranty cost on a part that was being manufactured by another company. Upon investigation by Industrial Spring it was discovered that the main cause of failure was due to tool marks, poor radius design and the introduction of hydrogen embrittlement into the part during the plating process. Industrial Spring was able to design and build four-slide tooling to correct the manufacturing and tooling design flaws. We also utilize a plater that we have worked with for many years that knows and fully understands how to correct issues that are sometimes caused with electro plating of high carbon wire and steel. With these corrections we have been able to eliminate the problems previously experienced saving the customer thousands of dollars in rework and warrantee costs.
