A line needs 2,000 components, so the warehouse issues a full reel of 5,000. The line uses 2,000 and returns the remaining 3,000. The return is booked, the reel goes back on the shelf. It sounds clean — except that the odd 3,000 on that reel may not be 3,000 at all.

In practice it usually isn't. The remainder gets established three different ways — by counting, by weighing, or by trusting the original label — and when the three disagree, a “close enough” figure goes into the system. The difference accumulates, one reel at a time.

1. The root cause: the issue unit is too large

If the smallest unit you can issue is a full reel, every issue produces a remainder, and every remainder needs a manual check. The more often you check, the more often you get it wrong.

A reel splitter attacks that structural problem directly: it breaks a large reel into small ones sized to demand, so the issue unit matches actual consumption and the remainder never exists in the first place.

2. How the D-1 works

The Youngpool D-1 splitting machine can take splitting instructions automatically from an MES system, or accept a quantity entered by hand. It covers 8/12/16/24 mm tape, handles both paper and plastic carrier tape, and takes pockets up to 15 mm deep.

Against manual work,  splitting and counting efficiency more than 30% higher, counting accuracy above 99%, and operator workload down by over 50%. What those numbers mean in practice is simple: splitting no longer depends on someone counting by hand. A machine does it — and does it the same way every time.

3. It is not only the counts that come right

Once splitting is in place, what moves through the warehouse is small reels sized to need, and what sits at the line side is the same. Half-used reels stop occupying shelf space, and finding, counting and returning material all get simpler.

Most plants buy a splitter to save money. What improves first is the state of the shop floor.

4. Setting the splitting rule

There are three common rules: by day — split according to the day's plan; by work order — split to the quantity the order actually needs; by batch — split a whole batch at once.

Splitting by day is flexible and suits high-mix, low-volume work. Splitting by work order is the most accurate, and suits stable orders with larger volumes. Splitting by batch is the least work, but carries the highest remainder risk.

Most plants end up with a hybrid: work order first, day as the top-up. Write the rule into the work instruction and let the machine follow it, and you stop getting one rule today and another tomorrow.

A remainder is not a stocktake problem. It is created the first time a whole reel is issued.
