Are you looking to reduce labor, changeover, and scrap costs?

Oscillate wound coil offers significant benefits over traditional ribbon wound coil. In this post, we will detail the differences between the two and provide examples of how much you can save with oscillate wound coil.

Pancake Coil


A traditional ribbon, or pancake, wound coil consists of a single steel strip that is wound on top of itself, like a roll of tape, until the maximum OD tolerance is reached.


Oscillate, or traverse, wound coils take pancake coils, which are welded together, and wind the strip back and forth on a traversing rewind drum, like that of a spool of thread or garden hose. Up to 10 pancake coils can be welded together and wound to significantly increase the coil’s linear footage and create one large oscillate wound coil. These welds are marked so they can be identified and removed during the customer’s end process.

The benefits of choosing oscillate wound coil over ribbon are significant.

Because of the oscillate coils increased linear footage, fewer changeovers are required resulting in decreased operational downtime and less material handling, thus increasing productivity, and improving worker safety. Heads and tails scrap are also reduced, saving overall material costs. Oscillate wound coil provides consistent quality and overall improved productivity for your operation.

How much can you really save?

Let’s assume a typical shift uses 20 ribbon wound coils with a changeover time of 10 minutes each. At a labor rate of $15 per hour, the total changeover costs can be calculated to $50/shift, $250/week, or $1,000/month.

However, using an oscillate coil that contains 10 ribbon coils, only 2 changeovers are needed per shift instead of 20. At the same labor rate, the total changeover cost using this oscillate wound coil is reduced by 90% to $5/shift, $25/week, or $100/month.

This results in a total labor savings of $900/month or $10,800/year.

But wait there’s more…

Not only are labor costs reduced, heads and tails scrap are also decreased. If we assume 5 pounds of scrap loss per ribbon wound coil, approximately 100 pounds of scrap is lost per day. With a material cost minus scrap value of $1.00 per pound, the total scrap cost lost is $100/day, $500/week, or $2,000/month.

Because the heads and tails of pancake coils are welded together on oscillate coils, scrap is also reduced by approximately 90% to only 10 pounds per day with a scrap loss of $10/day, $50/week, or $200/month.

Total scrap savings realized using oscillate wound coil is $1,800/month or $21,600/year.

Using this example, you can save approximately $32,400 annually by choosing oscillate over ribbon wound coil.
