Forming of a Chrome Silicon Spring for the Automotive Industry
At R.C. Coil Spring Mfg. Co., Inc., we manufacture vast quantities of springs that exhibit an elevated level of quality which is in high demand in the automotive industry. We produced the compression cam spring highlighted here for use in a car starter. Material of construction was .0258" diameter chrome silicon wire, chosen because of its ability to withstand high stresses and repeated impact loading. Manufactured using our high-tech coil compression equipment especially designed to create rectangular forms, this cam spring featured 5 ¼ coils wound to a length of 0.460” with elliptical diameter of 0.4" x .2". Tightly controlled and continually monitored production processes allowed us to repeatedly uphold ± 0.010" tolerances, first part to last, over a high volume production run.
Completely satisfied with the quality of this spring, the client contracted with us to supply 5 million units on an annual basis, which we produce in lots of 250,000 per release within a 4-5 week timeframe.
