OEM tooling registers are right on paper and wrong on the supplier's floor: molds sit at repair shops, dies change presses, and shot counts are typed at the last audit, so worn tools show up as quality problems. Agree five things first: one identity per tool, which presses count, four statuses set by location, a life limit and alert per tool, and who acts. Then an IoT device on the press counts shots, a self-powered tracker reports location, and both sides read the same record.
A register that is right on paper
Every OEM keeps a tooling register: asset number, part number, supplier, book value, status. In our experience it is right on paper and wrong on the supplier’s floor. A mold is listed at one supplier and is physically at an outside repair shop in another country. A die that the register shows on press 3 moved to press 5 two months ago because press 3 was busy. The shot count on the record is the one the supplier typed into a report at the last audit, and the date of the last maintenance sits in the supplier’s tool shop’s own file.
Nobody in this chain is careless. The fleet is simply spread over more places than any one person can see: dozens of suppliers, their warehouses and tool shops, their presses and outside repair shops. Each supplier keeps its own count in its own Excel, and the OEM reads it when it arrives. The tooling you paid for is the most expensive asset you own in a plant you do not run, and most of the time the least visible.
Why the quarterly report is not a count
The tool-condition report most OEMs receive is honest and late. Shots since the last maintenance are reconstructed from the supplier’s production records, mount and dismount are reported by hand, and the report is read weeks after the shots were made. Three things go wrong with that.
The tool reaches end of life during a ramp. The limit was on the register, the count was not, and the first sign was parts failing at the supplier’s inspection or at your line. The quality conversation came before the maintenance conversation.
Maintenance goes to the wrong tool. On a calendar, the mold that sat on a rack for two months gets a maintenance slot it did not need, while the one that ran three shifts on a hot part number waits for its date.
A transferred tool arrives with no history. When a part is resourced, the tool moves with a count that was never measured, and the new supplier starts from a number it cannot trust.
Five things to agree before any tracker ships
The hardware is the easy part. What makes a register true is a handful of agreements between your tooling people and the supplier’s tool shop, settled first.
- One identity per tool. Your asset number and the supplier’s own tool ID on the same record. A tool that exists twice on the register is counted twice or not at all.
- Which presses count. The supplier’s presses that run your tools, not the whole shop. One connected press counts shots for every tool that mounts on it, so the machine side stays small while the fleet grows.
- Four statuses and what sets them. In the warehouse or tool shop, on a machine, in repair outside the plant, scrapped at end of life. Location sets the status; a manual mount report stays as a backup where one press cannot be told from the next.
- A life limit and an alert threshold per tool. Agreed between your tooling engineer and the supplier’s tool shop, with the alert set early enough that a planned maintenance stop is still ahead when it fires.
- Who sees what, and who acts. The supplier sees its own presses and the tools on them; you see your tools across all suppliers. An alert is a task with an owner and a due date, not a discussion about whose count is right.
How the count and the location arrive
The press already knows how many shots it has made. Every machine produces the same basic electrical signals: running, stopped, cycle, count. A small IoT device connects to those signals; an electrician installs it in under an hour, with no PLC connection and no change to the machine’s programs, and the supplier’s own people can do it. From that moment every cycle on that press is counted, whether or not anyone fills in a form.
What differs from one machine to the next is not the signals. It is the machine, the process, the product and the operating environment, even for two presses standing side by side. The Universal Adapter in the cloud interprets the same signals with the context of that specific machine, and each counted shot is added to the tool mounted on it.
The tool reports its own position. A self-powered tracker sits on the mold or die on a magnetic cradle and sends its location over the cellular network, indoors and outdoors, with no wiring and nothing to install in the supplier’s plant. The battery lasts years at one update a day. Location sets the status, the press sets the count, and both sides read the same record.
For an OEM this sits inside the same picture as the rest of the supply chain. Supplier KPI Automation reads OEE, MTBF, MTTR and days on hand from each supplier’s MES or ERP through a read-only client the supplier installs; where a KPI needs a reason, nominated cells at the supplier connect at machine level; and the tooling you own at those sites is tracked on the same platform. That is what the Tools Tracking & Monitoring product is built for.
What the first months usually show
In the fleets we connect, the first weeks are mostly about the register catching up with reality. Tools listed at one supplier turn up at a repair shop or at a sister plant. Shot counts come in higher than reported for the tools on busy part numbers and lower for the ones that sat still, which is exactly why calendar maintenance was hitting the wrong tools. A few tools are already past the limit on their record and nobody had flagged them.
Then the pattern settles. The same tool shows a different cycle on two presses at the same supplier, which the tool shop usually explains in a minute: fixture, cooling, a setter’s habit. Limits that were conservative for some tools turn out optimistic for others, and your tooling engineer starts correcting them per tool and per press, the way a plant reviews a cycle time. The maintenance conversation now happens before the quality conversation.
What we learned
Start with the tools you worry about: the ones on a ramp, the single-source parts, the tools at a supplier whose days on hand are thin. Put trackers on the tools that travel, because those are the ones that get lost. Agree the limit and the alert per tool before the first alert fires, so that an alert means a task. And review the limits after the first maintenance cycle, per tool and per press, rather than once a year.

Questions people ask
How can an OEM know the real shot count of a mold at a supplier?
By counting from the press instead of from reports. A small IoT device connects to the press's electrical signals (running, stopped, cycle, count); the supplier's electrician installs it in under an hour with no PLC connection and no change to programs. Each counted shot is added to the tool mounted on that press, and the OEM and the supplier read the same running total.
How is the location of OEM-owned tooling tracked at suppliers?
A self-powered tracker on the mold or die, on a magnetic cradle, sends its position over the cellular network, indoors and outdoors, with no wiring and no infrastructure in the supplier's plant. Location sets the status: in warehouse or tool shop, on a machine, in repair outside the plant, or scrapped. A manual mount report stays available as a backup.
What should an OEM agree with a supplier before tracking its tooling?
One identity per tool (OEM asset number plus the supplier's tool ID), which presses count, the four statuses and what sets them, a life limit and an alert threshold per tool agreed with the supplier's tool shop, and who sees what and who owns an alert. These agreements, not the hardware, are what make the register true.
