Metal Stamping Die Maintenance Video

Manor Tool & Manufacturing Company has more than 50 years of experience in metal stamping and hard tooling. To maintain quality and process reliability, we perform regular in-house die maintenance following each production run and review every piece to ensure continued performance.

During maintenance, each die is visually inspected and cleaned of debris. Springs are removed for inspection and replaced if worn, and important features are refinished or sharpened using abrasives. The die is then reassembled and lubricated before being returned to storage.

We are able to store hundreds of dies in our facility for repeat production runs, allowing us to quickly resume manufacturing and deliver parts whenever they are needed.

What Happens During Stamping Die Maintenance

1. Inspect after every run. When a production run ends, the die comes out of the press and is visually inspected, and the parts from the run are reviewed so any burrs, wear or dimensional drift are caught before the next order.
2. Clean. Slugs, debris and old lubricant are removed from the die sections, stripper and guide components.
3. Service springs and wear components. Springs are pulled and inspected and replaced if they are worn, so the stripper and pressure pads keep working the way the die was designed.
4. Sharpen and refinish. Cutting edges and critical features are refinished or sharpened with abrasives and surface grinding in our tool room.
5. Reassemble, lubricate and store. The die is reassembled, lubricated and returned to storage, ready for the next release.

Why Maintenance After Every Run Matters

Dull cutting edges raise burrs, worn springs let the strip lift or misfeed, and debris can mark parts or damage a station. Catching these between runs costs far less than a die crash in the middle of production. For a breakdown of preventive versus reactive spend, see our guide to metal stamping die maintenance cost.

Die Storage for Repeat Orders

We store hundreds of customer dies in our Schiller Park, Illinois facility. Because each die is maintained before it goes back on the shelf, repeat orders can go straight into the press without waiting on tool room work.

Repair, Rework and Transferred Tooling

Our in-house tool room handles die repair and rebuilds as well as routine maintenance, with CNC machining, wire EDM and surface grinding under the same roof. We maintain and repair dies we built and dies built by other shops, including tooling transferred from another supplier. When a die is wearing out, our die repair vs. die replacement framework explains how we decide between reconditioning and a rebuild.

Frequently Asked Questions

How often should stamping dies be maintained?

Manor Tool maintains dies after every production run. In general, the right interval depends on the number of hits, the material being stamped and how abrasive it is, but servicing a die between runs keeps problems from carrying into the next order.

What is included in stamping die maintenance?

Inspection of the die and the last parts produced, cleaning, spring inspection and replacement, sharpening or refinishing of cutting edges and critical features, reassembly and lubrication.

Can Manor Tool maintain dies built by another shop?

Yes. We maintain and repair customer-supplied tooling and dies transferred from other suppliers, as well as the dies we design and build in house.

What is the difference between die maintenance and die repair?

Maintenance is the routine service done after each run to keep a die in specification. Repair fixes damage or wear that has already affected the die, such as a cracked section, a broken punch or worn forming stations.
